Answer:

The answer is Germinal mutation.

Explanation:

In Eukaryotes we find two types of cells, one is somatic cell or vegetative cell and the other is germ cell. If the mutation occurs in germ cell then it is inherited to the next generation because germ cells give rise to gametes which fuse with other gamete during mating. So only such mutations can cause evolutionary change. If the mutation occurs in somatic cell, its not inherited and thus plays no role in evolution. Mutations occurring in germ cells are called germ-line mutation or germinal mutation.

Heat transfer by radiation _________. A) is not possible from human beings to their environment. B) does not occur from light bu

Alja [10]

I believe the answer is C.

This is because radiation is emitted. It does not need to be channeled or conducted. So, for this reason, I believe heat from radiation also does not need any matter to conduct it.

Hope this helped. Have a great day!

Now, suppose that the three tomato genes from Part A did not assort independently, but instead were linked to one another on the

suter [353]

Answer:

c. All eight possible phenotypes could occur, but a greater proportion of the offspring would have the parental phenotypes

Explanation:

When genes are linked they do not assort independently. Instead, the alleles on the parental chromosome will have a tendency to migrate together to the same pole of the cell. To produce gametes with genotypes different than the parentals crossing over must happen between the genes of homologous chromosomes during meiosis. However, recombination is a rare event, so the recombinant gametes will be less frequent than the parentals (those that arise when no recombination occurs between genes) and for that reason a greater proportion of the offspring will have parental phenotypes.
