The graph illustrates the frequencies of two genotypes, AA and Aa, over many generations. The recessive condition, aa, results in sickle cell anemia. Wince this is a recessive condition, individuals with Aa or AA do not display the sickle cell phenotype. What statement explains what is shown in the graph beyond generation 35 for this gene?
A) Individuals with the heterozygous condition replaced individuals with either homozygous condition.
B) All of the individuals with aa phenotype died, leaving only individuals displaying the dominant phenotype.
C) Females preferred mating with Aa individuals, resulting in a continued presence of the recessive (a) allele.
D) The population reached equilibrium for this trait, as the genotype frequencies stabilized after 35 generations.

What evidence could be used to convince policy makers to change a shipping lane from going through a whale breeding ground? information on the number of all whale species currently alive information on the number of all whales hit by boats in the given area information on the number of whale deaths in the world's oceans information on the number of whale offspring born every year. (a) scientists could collect and combine data on fish populations all around the world to show that their populations are declining. (b) scientists collect and combine data on fish populations all around the world to show that their populations are increasing. (c) scientists work together and use past data to show that fish populations are becoming locally extinct in some areas. (d) scientists work together and use past data to show that some fish populations are adapting to environmental changes.
