A.) Study of mutations reveals that: a.) mutations that lead to shortened proteins often have high negative selection coefficients b.) most mutations that affect fitnes are synonymous mutations c.) most non-synonymous mutations have positive selection coefficients d.) mutations that have major effects on the phenotype are the most common.
Hello, I need help answering 3.a, b, & c questions. Pls and thank you
3. A.) Study of mutations reveals that:
a.) mutations that lead to shortened proteins often have high negative selection coefficients
b.) most mutations that affect fitnes are synonymous mutations
c.) most non-synonymous mutations have positive selection coefficients
d.) mutations that have major effects on the
B.) Natural selection during the final stage of allopatric
a.) increased post-zygotic isolation in a hybrid zone
b.) more gene flow to form a "hybrid swarm"
c.) increased pre-zygotic isolation in a hybrid zone
d.) negative assortive mating
C.) Human hunting of wild animals, such as deer or bighorn sheep, usually:
a.) leads to evolution in the same direction as that favored by natural selection in the non-hunted populations
b.) causes males to have more extreme sexual characters (such as horn size)
c.) creates artificial selection in a direction that opposes natural selection
d.) leads to animals breeding at older ages
