The hardy–weinberg equilibrium model states that allele and genotype frequencies in a population will remain constant from generation to generation in the absence of other evolutionary influences. because one or more of the influences listed above are typically present in real populations, the hardy–weinberg model describes an ideal condition against which the effects of these influences can be analyzed. of the influences listed, which would not cause a change in allelic frequencies or genotype? a) mutation b) genetic drift c) mitotic divison d) sexual selection

One statements is an example of a scientific observation. another statement is an example of a scientific explanation. identify the correct statement for each category to illustrate how scientific explanations are inferred from scientific observations.

Suppose a particular species of tulip plant has three alleles for the gene that codes for flower color. the cr allele produces red tulips, the cp allele produces purple tulips, and the cw allele produces white tulips. cr is dominant over cp and cw, and cp is dominant over cw. for each of the following crosses, determine the expected ratio of offspring for each flower color. cr cp x cp cw cr cw x cp cw 1 red: 1 purple : 0 white, 1 red: 2 purple: 1 white, 2 red: 1 purple 1 white, 1 red: 3 purple : 0 white, 2 red: 0 purple : 2 white, 2 red: 2 purple : 0 white
