Question
Chapter 15, Problem 5GP
a.
Summary Introduction
To explain: The genotypes of the parent if the female chicks are found to be black.
Introduction: The birds have ZW sex-determination system, which is a chromosomal system in birds. This system is found in some birds, moths, butterflies, and fishes. Here, the males have homogametic sex (ZZ) and the females have heterogametic sex (ZW).
b.
Summary Introduction
To explain: The genotypes of the parents if the males and females are evenly represented in the black and barred chicks.

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.
