(Purple flower is dominant over white.) - All of the offspring had purple flowers Worker honeybees are - Sterile females Kin selection refers to - An animal promoting the survival of the genes of its close relatives The genetic makeup of an individual is the - Genotype In a test cross, what percentage of the offspring will have the same phenotype as the tested parent if the parent if the the parent to be tested is homozygous - 100% Codominance occurs when - both of the alleles in a heterozygote are equally expressed phenotypically in an individual. When the expression of a trait is influenced by the action of many genes, the pattern of inheritance is called - Polygenic inheritance What is the advantage of play? - Play is a chance to practice skills such as hunting, fleeing, and social behaviors.
