Textbook Question
Chapter 11, Problem 1GP

phenotypes of offspring could be obtained? - b. If one of the offspring bulls in part (a) were mated to a white cow, what genotypes and phenotypes of offspring could be produced? In what proportion?

During breeding season, lizards attract mates by bobbing their heads and displaying colorful throat patches. The genes for these traits are on different chromosomes. Fast bobbing heads (F) and red throat patches (R) are dominant to slow bobbing heads and yellow patches.
a. A male lizard heterozygous for head bobbing and homozygous dominant for the red throat patch mates with a female that is also heterozygous for head bobbing but is homozygous recessive for yellow throat patches. How many of their offspring will have fast bobbing heads and red throat patches (assume 16 young).
b. Assume that lizards prefer to mate with other lizards with fast bobbing heads and red throat patches. What percentage of the offspring from “A” will lack mates because they are slow bobbers with yellow throats?
c. What percentage of the offspring from “A” will have only one of the two desired traits?
