Mouse fur color is determined by a single gene with two straight up dominant and recessive alleles. Black fur is dominant to white fur. 100 mice are randomly selected from a population – 50 mice are black and 50 mice are white. Use the Hardy-Weinberg equation to calculate the genotypic frequency of homozygous dominant, heterozygous and homozygous recessive individuals in the population.

Cladistics is a way of classifying organisms by examining the characteristics of their ancestors and descendants and depicting the relationships in a cladogram. which of the following best describes a challenge in classifying organisms this way? a. there are millions of species on earth, and a cladogram is not a practical means for classifying all of them. b. it is impossible to tell which organisms are most closely related to each other using a cladogram. c. cladograms are detail-oriented and do not provide a useful understanding of evolutionary relationships. d. there is a limited number of ways to organize the information, so most cladograms end up looking very similar.
