Small burrowing animals can cause the soil to gain nutrients (because of some...leftovers the animal may leave) And rocks may sink into the soil because of empty spaces in the soil. but the nutrients is the most important part because it will help more plant's ability to grow and reproduce.

mezya [45]

Options for the question are not given. They are as follows :

A.  Mate them and see what color the offspring are—that will be the dominant color

B.  Mate them and see what color the offspring are—the other will be the dominant color

C.  Mate them, and then mate their offspring to see what color the next generation is

D.  Mate them together, and then mate their offspring to see what color the next generation is—the other color will be the dominant color

Answer:

A.  Mate them and see what color the offspring are—that will be the dominant color

Explanation:

Out of the two colors, one will be recessive and one will be dominant. Recessive color will be homozygous since it is only expressed in homozygous condition. It is also given that in this cross the dominant color is also in homozygous condition.

When the guinea pigs mate, the resulting progeny will obtain one dominant allele from the dominant color parent and one recessive allele from the recessive color parent. The progeny will be heterozygous and show the dominant phenotype since the dominant allele will mask the recessive allele. Thus, the color which is visible in their offspring will be the dominant color.

Answer:

People who acquire advantageous features have a greater chance of surviving, whereas individuals who have less useful traits are weeded out by natural selection. The higher the diversity of characteristics in a population, the greater the population's chances of survival.
