If the genotype of both parents was Aa, what would be expected of the genotypes among their possible offspring? Half would have
the genotype AA. Half would have the genotype Aa. Three-quarters would have the genotype aa. Three-quarters would have the genotype Aa.

Answer:
The correct answer would be "Half would have the genotype Aa".
The genotype of both parents is Aa. So, each of them would produce two types of gametes one of which contains A and other would contain a.
The cross would produce offspring with three possible types of genotypes AA, Aa, and aa in the ratio 1:2:1.
Thus, one-fourth of the offspring would have genotype AA, two-fourth or half of the offspring would have the genotype Aa, and one-fourth would have aa.

Explanation:
B. serves as the control center of the cell and contains the cell's genetic information
All the genetic information within the eukaryotic cell is stored within the nucleus as helical DNA. This DNA is tightly wounucleuscarbohynd around histones as chromosomes. Chromosomes within the nucleus is unwound, unzipped and read by enzymes in a complex series of steps known as transcription. The message on DNA, called genes is copied by RNA polymerase, to form mRNA complementary sequence to that of the DNA strand. These are then translated into proteins in ribosomes.
Further Explanation:
A cell's structural components (i.e. their makeup) determine their function (what they do) . For instance, photosynthesizing cells in algae and plants have structures called chloroplasts. These contain chlorophyll, a specialized compound which facilitates the conversion of light energy to energy stored in carbohydrates. In specific cell types, collected proteins may function as a unit called an organelle. Some organelles are bound by membranes like those that make up the external structure of the cell, with varying compositions of phospholipids and proteins. These are advantageous, as they:
- may increase metabolic reaction efficiency; they allow cells to concentrates smaller fractions of enzymes and solutes
- separate proteins and molecules that me harm the cell by parceling them into membrane-bound organelles for example, proteaseas bound within lysosomes can break down many structural proteins
