Definitely C) she did not have enough information to prove her theory to be right.
a slightly tremulous effect imparted to vocal or instrumental tone for added warmth and expressiveness by slight and rapid variations in pitch.
According to the image, the fish underwent sympatric speciation. The new species of fish had mating seasons that were different from that of the original fish. Because of the differences in mating seasons, the fish underwent reproductive isolation. This mode of isolation would be temporal.
Sympatric speciation happens within a population of an organism that gets isolated reproductively due to differences in their mating periods. This time dependent isolation is called temporal isolation. Example, a fish population can split into two if some of the fishes start mating early in the spring while the rest mate late in the autumn. The spring-mating population will not become compatible to mate with the late-autumn-mating population.
Answer:
F = dominant, free earlobes
f = recessive, attached earlobes
father is "ff" then he has only two recessive attached earlobe alleles meaning he can only have attached earlobes. This is his phenotype, the visible trait produced by the genotype.
The mother is said to be "Ff". She has one dominant free earlobe allele (F) and one recessive attached allele (f). The dominant allele gets expressed as the visible trait (phenotype). = free earlobes
