Answer:
Purpose: Meiosis is a special version of cell division that occurs only in the testes and ovaries; the organs that produce the male and female reproductive cells; the sperm and eggs. ... Therefore the purpose of meiosis is to produce gametes, the sperm, and eggs, with half of the genetic complement of the parent cells.
Genetic variability is a measure of the tendency of individual genotypes in a population to vary (become different) from one another. Variability is different from genetic diversity, which is the amount of variation seen in a particular population.
Meiosis generates genetic diversity through a process called crossing over which allows new combinations of variations to appear in gene pool. ... Chiasmatal points appear randomly on homologous chromosomes, hence amount of genetic material exchanged in every case/cell could be different.
Explanation:
The flower would be Genotype
Answer:
<h2>c. Both alleles are recessive, but they must be located at different gene loci.</h2>
Explanation:
Given:
If he inbred normal mice and obese mice , all the F1 mice are normal.
F1 and F1 interbred : 8 are normal and 2 are obese.
obese and obese = all are obese.
hence O1 proved as recessive allele.
in second experiment :
O2 is proved as recessive allele.
But when both obese mice of different laboratories are inter-crossed, all the offspring are normal, hence it is proved that Both alleles are recessive, but they must be located at different gene loci.

Answer:
D. Active transport.
Explanation:
Active transport is the method that uses the ATP's energy to move ions and molecules from one side to the other of the membrane. The elements move from a place of lower concentration to one of a higher concentration. They move against their concentration gradient, which is why they need the energy to do it. There are two types of active transport, primary and secondary.
The primary active transport is ion pumps that hydrolyze ATP using one of the phosphates of the ATP to change the pump's shape and move the elements against their concentration gradient. It uses the ATP's energy directly.
The secondary active transport does not use ATP directly. It uses the electrochemical gradient that the primary transport had created when hydrolyzing ATP to transport the ions and molecules.
