In the breeding season, male lizards court females by bobbing their heads up and down while displaying a colorful throat patch. Assume for this question that both males and females bob their heads and have throat patches. Now, suppose that these lizards prefer to mate with lizards who bob their heads fast (F) and have red throat patches (R) and that these two alleles are dominant to their counterparts, slow bobbing (f) and yellow throats (r). A male lizard homozygous dominant for head bobbing and heterozygous for the red throat patch mates with a female that is heterozygous for head bobbing but is homozygous recessive for yellow throat patches. How many of the F1 offspring have the preferred fast bobbing / red throat phenotype (assume 16 young)? Show your work
