Complete question:
Thinking creatively about evolutionary mechanisms, identify at least
two schemes that could generate allelic polymorphism in a population except natural selection that favors heterozygotes.
<u>Select the two correct answers.</u>
-inbreeding among individuals in the population
-purifying selection against mutational variants of alleles in the population
-continuous migration of individuals with new alleles into the population
-mutations that do not severely affect viability and reproductivity
-genetic drift of alleles common in the population
-events leading to genetic bottleneck effect
Answer:
The two events that might favor heterozygotes among the options are
- The Continuous migration of individuals with new alleles into the population
- Mutations that do not severely affect viability and reproductivity. These might favor heterozygous frequencies.
Explanation:
Due to technical problems, you will find the complete explanation in the attached files.
Answer:
agouti - aaBbCc
solid color - AaBBCC
agouti black - AAbbCc
albino - AaBbcc/Aabbcc/AABBcc
Explanation: All the phenotypes that contain cc will be albinos, so they won't present any pigment deposition. Agouti black depends on the A gene to be homozygous and the B to be recessive, so the phenotype AAbbC_ is the correspondent. If A is not homozygous and B isn't recessive, we have agouti color. If B is homozygous and A recessive, we have a solid color.
