Leave all the homozygous recessive offspring unshaded. Across between parents of which genotypes would yield 100% heterozygous offspring? 7e1. Codominance and…Mutations Can Uncouple Chromosomal Sex from Phenotypic Sex Give an example of a situation in which genetic sex, gonadal sex, and phenotypic sex do not coincide. Explain why they do not coincide.Why are polyandrous mating systems more rare than polygynous matings? Only males are capable of multiple rounds of reproduction within a single breeding season Only females care for the young Females usually experience more intrasexual selection pressure than males Females usually devote more energy to offspring production and development.
