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?
0)
Individuals with the heterozygous condition replaced individuals with
either homozygous condition.
All of the individuals with a phenotype died, leaving only individuals
displaying the dominant phenotype.
Females preferred mating with Aa individuals, resulting in a continued
presence of the recessive (a) allele.
The population reached equilibrium for this trait, as the genotype
frequencies stabilized after 35 generations.

Recombinant dna (rdna) creates offspring which are genetically identical to the parent is the process of breeding only organisms with desirable traits involves the removal of the nucleus of a cell combines genes from organisms of different species in a lab

Awoman whose sister tested positive for a specific mutation in the brca1 gene, which increases the risk for breast and ovarian cancer, is found not to have that mutation but does have a mutation of unknown significance near the known mutation site. how should this woman be counseled? select one: a. she should be informed that her risk for breast cancer is greater than the general population but not as great as her sister’s risk. b. she should be informed that because she does not have the mutation, her risk for breast cancer is not greater than that of the general population. c. she should be informed of her gene mutation status and be presented with all the available prophylaxis options and reconstruction options. d. she should be informed that she does not have the specific mutation but that because another mutation is present she should be vigilant about screening

I’m stuck on this question cuz i’m stupid sksksksk
