I was a kid; 〃royalty〃
  
  was a bad joke based on the worst possible breeding methods。
  
  Captain Sheffield investigated next a lower incidence of a bad gene: Assume a lethal gene in the gene pool from whi h Joe and Llita's parents。 were derived。 Being lethal; it。 could exist in an adult zygote only if it was masked in gene…pair by its benign twin。 Assume a 5 percent masked incidence in zygotes…still too high to be realistic for a lethal gene…but check it anyhow。 What trend would show?
  
  Parent zygote generation: 100 females; 100 males; each a possible parent for Llita and for Joe…and 5 of the females and 5 of the males carry the lethal gene; masked。
  
  Parent haploid stage: 200 ova; 5 of which carry the lethal gene; 200 spermatozoa; 5 of which carry the lethal gene。
  
  Son…and…daughter zygote generation (possible 〃Joes〃 and possible 〃Uitas〃): 25 dead through reinforcement of lethal gene; 1;950 carrying the lethal gene masked; 38;025 〃clean〃 at that site。
  
  Sheffield noted that a hypothetical hermaphrodite had crept in through not doubling his sample size in order to avoid anomaly through odd numbers; Oh; the hell with!…it did not change the statistical oute。 No; do it!…start with a sample of 200 males and 200 females with the same lethal…gene incidence for that site。 This gave him:
  
  400 ova; 10 with the lethal gene;
  
  400 spermatozoa; 10 with that lethal gene…10')
  
  …which gave in the next zygote generation (possible 〃Joes〃 and 〃Llitas〃): 100 dead; 7;800 carriers; 152;100 〃clean〃… which changed no percentages but got rid of that imaginary hermaphrodite。 Sheffield considered briefly the love life of an hermaphrodite; then got back to work。 The numbers became very cumbersome; jumping to the billions in the next zygote generation (i。e。; Little Nameless; now just started in Llita's belly )…l 5;210;000 culled by reinforcement; 1。216。800;000 carriers; 24;336;000;000 〃clean〃…and again he wished for a clinic puter and tediously converted the unhandy numbers into percentages: 0。059509 percent; 4。759 percent; 95。18 percent plus。
  
  This showed a decided improvement: approximately 1 defect out of 1;680 (instead of 1 out of 1;600); the percentage of carriers decrease to below 5 percent and the number of 〃clean〃 increased to above 95 percent in one generation。
  
  Sheffield worked several such problems to confirm what he had seen by inspection: A child from plementary diploid (〃mirror twins〃) had at least as much chance of being healthy as did the offspring of unrelated strangers…plus the happy fact that such a baby's chances were improved by culling at one or more stages by the priest…scientist who had initiated the experimention … almost certain assumption and one that made Joe the best possible mate for his 〃sister〃 rather than the worst。
  
  Llita could have her baby。
  
  VARIATIONS ON A THEME

  Valhalla to Landfall
  
  …the best I could for them; Minerva。 Every so often some idiot tries to abolish marriage。 Such attempts work as well as repealing the law of gravity; making pi equal to three point zero; or moving mountains by prayer。 Marriage is not something thought up by priests and inflicted on mankind; marriage is as much a part of mankind's evolutionary equipment as his eyes; and as useful to the race as eyes are to an individual。
  
  Surely; marriage is an economic contract to provide for children and to take care of mothers while they bear kids and bring them up…but it is much more than that。 it is the means this animal; Homo sap。; has evolved…quite unconsciously…for performing this indispensable function…and be happy while doing so。
  
  Why do bees split up into queens; drones; and workers; then live as one big family? Because; for them; it works。 How is it that fish do okay with hardly a nodding acquaintance between mama fish and papa fish? Because the blind forces of evolution made that way work for them。 Why is it that 〃marriage〃…by whatever name…is a?universal institution among human beings everywhere? Don't ask a theologian; don't ask a lawyer; this institution existed long before it was codified by church or state。 It works; that's all; for all its faults it works far better by the only universal test…survival…than any of the endless inventions that shallow…pates over the millennia have tried to substitute for it。
  
  I am not speaking monogamy; I mean all forms of marriage…monogamy; polyandry; polygyny; plural and extended marriages with various thrills。 〃Marriage〃 has endless customs; rules; arrangements。 But it is 〃marriage〃 if…and…only…if the arrangement both provides for children and pensates the adults。 For human beings; the only acceptable pensation for the drawbacks of marriage lies in what men and women can give each other。
  
  I don't meast 〃Eros;~' Minerva。 Sex baits the trap; but sex is not marriage; nor is it reason enough to stay married。 Why bteed a cow when milk is cheap?
  
  panionship; partnership; mutual reassurance; someone to laugh with and grieve with; loyalty that accepts foibles; someone to touch; someone to hold your hand…these things are 〃marriage;〃… and sex is but the icing on the cake。 Oh; that icing can be wonderfully tasty…but it is not the cake。 A marriage can lose that tasty 〃icing〃…say; through accident… and still go on and on and on; giving deep happiness to those who share it。
  
  When I was a rutty and; ignorant youngster; this used to puzzle me… (Omitted)
  
  …as solemnly ceremonious as I could swing。 Man lives by symbols; I wanted them to remember this occasion。 I had Llita dress in her notion of fanciest best。 She looked like a bloomin' Christmas tree; but I told her she looked beautiful… which she did; brides can't help it。 Joe I dressed in some of my clothes and gave them to him。 Me I dressed in a preposterous ship's…captain uniform; one I had for use on plas where such nonsense is customary…。four wide gold stripes on my cuffs; chest spangled with decorations bought in hockshops; a cocked hat Admiral Lord Nelson would have envied; and the rest as fancy as any grand master of a lodge。
  
  I preached 'em a sermon loaded with solemn amphigory most of it lifted from the only church they knew; the established religion of Blessed…easy for me; having been a priest there myself…but I added all sorts of things; telling her what she owed him; telling him what he owed her; telling them both what they owed the child in her belly and the other children they would have…and tacked on; for both but primarily for her; a warning that marriage was not easy; not to be entered into lightly; because there would be troubles they must face together; grave troubles that would require the courage of the Cowardly Lion; the wisdom of the Scarecrow; the loving heart of the Tin Woodsman; and the indomitable gallantry of Dorothy。
  
  That got her to weeping; so Joe started to drip tears…which was just what I wanted; so I had 'em kneel and prayed over them。
  
  Minerva; I make no apology for hypocrisy。 I didn't care whether some hypothetical God heard me or not; I wanted Llita and Joe to hear it…first in that jargon of Blessed; then in English and Galacta; then topped it off by intoning as many lines of the Aeneid as I could remember。 When I got stuck I closed with a schoolboy song:
  
  第25节
  
  Omme bene
  
  Sine poena; …
  
  Tempus est ludendi;
  
  …Venit hora
  
  Absque mora;
  
  Libros deponendi!*
  
  …and ended with a resounding 〃So mote it be!〃 Had 'em stand; take each other's hands; and declared that; by the supreme authority vested in me as master of a vessel in space; they were now and forever husband and wife…kiss her; Joe。
  
  All to a muted background of Beethoven's Ninth… That doggerel got in by accident when I had run out of 〃punishment lines〃 of Virgil and needed a few more impressive sounds。 But when I thought about it later; I saw that it translated as appropriately for their honeymoon as for a school holiday。 All was indeed well; now that I knew that this joining of siblings could take place sine poena…without fear of geic punishment。 And ludendi translates as 〃amorous play〃 or 〃Eros〃 as readily as 〃gambling〃 or 〃children's play〃 or any other frolic。 And I had declared a four…day ship's holiday; no work for them; no study hours…libros deponendi…starting at once。 Sheer accident; Minerva。 It was simply a bit of Latin verse that came into my head…and Latin is majestic; especially when you don't understand it。
  
  We had a fancy supper; cooked by me; that lasted about

  Without punishment;
  
  The time is for playing;

  Without delay
  
  For laying (school) books down。
  
  Purists will see that the Senior gave this jingle a poor translation。 But one wonders why he did not continue in the same vein with the cheerfully bawdy triple pun available in the last line by substituting 〃liberos〃 for 〃libros〃? That he could have missed it seems out of character。 Our Ancestor's capric disposition is everywhere evident; his occasional professions of asceticism have
