Answer:
D
Explanation:
This involves a dihybrid inheritance I.e. two genes are being passed on. During meiosis, specifically, the Prophase stage, homologous chromosomes (similar but non-identical chromosomes received from each parent) line side by side. According to the question, one chromosome contains A and B alleles and its homologue, received by the other parent carries a and b alleles. This means that the diploid individual has a genotype AaBb for that gene.
According to Mendel's law of independent assortment, the alleles separate independently of one another into gametes. I.e. allele A and a separates into the gametes without affecting alleles B and b of the other gene.
Crossing-over, which is the exchange of chromosomal segment occurs between the two homologues. Hence, the exchange of chromosomal segments containing alleles in the individual will possibly produce four gametes with the genotypes: AB, Ab, aB, ab.
B is your answer for that question
Answer:
Your white blood cells are part of the immune system (helps fight off disease) while your red blood cells are part of the circulatory system (transports oxygen and carbon dioxide between the lungs and the rest of the tissues in the human body)

Explanation:
-Evolution is a gradual change in the inherited traits of a population over many generations. Natural selection is a mechanism where the members of a population best suited to their environment have the best chance of surviving to pass on their genes.
- Evolution is the precessions by which population changed over time whereas natural selection is the process by which individuals that are better adapted to their environment survive and reproduce more successfully than less well adapted individuals do
