Answer #1

Ans:

c. Mutations

Explanation: Mutation is the phenomenon where sudden, heritable changes occurs. This changes create novel variations on the population I.e. gives a new trait that doesn't present before and may serve as raw materials for evolution. Predators is the organisms that kill prey. So, predators can change frequencies of prey within the population. Abiotic factors are the non-living factor that present in populations or community, it doesn't create novel variations. Environment is the surroundings in which the living and non-living things lives and operates. Environmental variation helps the organism to adapt to a new environment.

In minks, color variation can be attributed to two genes: P and I.  The P locus gives dark in P- and platinum in pp, while the I locus gives dark in I- and imperial platinum in ii. When both the pp and ii mutations are present, the resulting mink has a sapphire colored coat. The traits are inherited in a Mendelian manner. If true breeding dark and sapphire minks are bred, produce an F1 which are then allowed to mate among...

You are studying two isolated populations of birds living on two different islands. In particular, you are interested in studying two different traits in these birds: beak size and feather color. Beak size is determined by a single gene exhibiting incomplete dominance. Birds with 2 copies of the A allele (genotype AA) have large beaks, birds with 1 copy of the A allele (genotype Aa) have medium beaks, and birds with no copies of the A allele (genotype aa) have...
