1. The peppered moth (Biston betularia) has two phenotypic forms, melanic (dominant) and peppered (recessive). The moths face predation by birds, and the predation is selective against different-colored tree trunks. In an industrialized area, one in which the tree trunks are dark like the melanic form (and thus hide the melanic forms from the birds), a sample of moths indicated that the frequency of the allele for peppering was 0.6; the next year, it was 0.5. What is the tness of the peppered genotype under this circumstance
2. V. C. Wynne-Edwards suggested that birds form ocks so that they can assess their population numbers. When they assess that their numbers are high, they decide not to breed for the good of the species, so that they do not exhaust their resources. Edwards called this process group selection. Why can t this mechanism work, given that it involves behavior that is for the good of the species

2 Mendel s Principles 21. RrTt self yields: 1. Dwarf F2 (1/4 of total F2), when selfed, produce all dwarf progeny (tt). Tall F2 (3/4 of total F2), when selfed, fall into two categories: 1/3 (TT, 1/4 of total F2) produce all tall, and 2/3 (Tt, 1/2 of total F2) produce tall and dwarf progeny in a 3:1 ratio. (The 3:1 ratio is from 1/2 the F2, so the tall component is 3/8 of the total F3 [3/4 1/2], and the dwarf is 1/8 of the total F3 [1/4 1/2].) Overall, the F3 are 3/8 TT (tall), 2/8 Tt (tall), and 3/8 tt dwarf (see g. 2.7). 3. Rule of segregation: adult diploid organisms possess two copies of each gene. Gametes get one copy. Fertilization restores the diploid number to the zygote. Rule of independent assortment: alleles of different genes segregate independently of each other. 5. Black is dominant, white is recessive, and both parents were heterozygous.The progeny are in an approximate 3:1 ratio. Since both parents had the same phenotype, the simplest cross is Bb Bb. 7. The disease is recessive at the individual level but incompletely dominant at the enzymatic level. Check the glossary for de nitions. 9. Ll Ll. Let L long ears and l no ears. We see three phenotypes in an approximate 1:2:1 ratio. One of the phenotypes (short) is intermediate between long ears and no ears. Therefore, we have incomplete dominance. 11. Washed eye mutant, We; wild-type, We . (W is already the allelic designation for the wrinkled phenotype.) 13. All. Since the child was type A, it must have gotten the IA allele from its mother. The other allele in the child is either IA or i. A type A (IAIA or IAi), type B (I BI B or IBi), type O, or type AB man could have supplied either an IA or i allele. 15. Universal donor, type O (no red-cell antigens); universal recipient, type AB (no serum antibodies). 17. All AB; or 1/2 AB, 1/2 A; or 1/2 AB, 1/2 B; or 1/4 A:1/4 AB:1/4 B:1/4 O. Crosses can be IAIA IB IB, IAIA IBi, IAi IBIB, or IAi IBi. IAIA IBIB IAi IBIB 1/16 RRTT red, tall 2/16 RRTt red, medium 1/16 RRtt red, dwarf 2/16 RrTT pink, tall 4/16 RrTt pink, medium 2/16 Rrtt pink, dwarf 1/16 rrTT white, tall 2/16 rrTt white, medium 1/16 rrtt white, dwarf 23. Choice (b) is preferred because although each will give the correct genotype, generally, testcrossing has the greatest probability of exposing the recessive allele in a heterozygote. For example, an Aa genotype, when selfed, produces aa offspring one-fourth of the time; when testcrossed, aa offspring appear one-half of the time; and when crossed with the Aa type (backcross), aa offspring occur one-fourth of the time. Thus, with a limited number of offspring examined per cross, testcrossing most reliably exposes the recessive allele. 25. The F1 are tetrahybrids (Aa Bb Cc Dd). If selfed, an F1 would form 24 16 different types of gametes; 24 different phenotypes would appear in the F2, which would be made up of 34 81 different genotypes; 1/(16)2 1/256 of the F2 would be of the aa bb cc dd genotype. 27. a. In the rst cross, look at the yellow-to-green ratio, 120:43 almost exactly 3:1. Therefore, yellow is dominant and both parents must be heterozygous. Now look at the tall-to-short ratio, 122:41. Again, we see a 3:1 ratio, which indicates that tall is dominant and each parent is heterozygous. Thus, the cross is probably YyTt YyTt. b. In the second cross, there are no tall progeny. Therefore, either the short phenotypes are homozygous, or short is dominant and at least one parent is homozygous. In the absence of the rst cross, we can t determine the mode of inheritance of height. We can, however, conclude that yellow is dominant (we got a 3:1 ratio) and that each parent is heterozygous. Based on the rst cross, we can conclude that this cross is Yytt Yytt. c. In the third cross, we see 41 yellow:46 green, and 45 tall:42 short. Both of these ratios are 1:1, and all we can conclude is that these ratios result from matings between a heterozygote and a recessive homozygote. With only this cross, we can t determine dominance. However, we can if we use all three crosses. The cross is yyTt Yytt.

19. Steve and his anc could be related. Both the dean and Steve s father must be IAi to produce O children, and each could have contributed M to produce M offspring. If the dean and Steve s father each contributed an S allele, the daughter would be SS. Note that if the daughter had B blood, she and Steve could not be related.
