Answer:
The DNA code contains instructions needed to make the proteins and molecules essential for our growth, development and health. The cell reads the DNA code in groups of three bases. Each triplet of bases, also called a codon, specifies which amino acid will be added next during protein synthesis.
Answer:
During the creation of oocyte, 3 additional haploid cells are created that will not be fertilized these cells are called Polar bodies.
Explanation:
The process of formation of oocyte is known as the Oogenesis. The oogenesis is the formation of oocyte which is capable of being fertilized, and the process begins even before the birth of the child. The oogonia is a diploid cell which undergoes mitosis to form the primary oocyte.
The primary oocyte then undergoes first meiotic division forming the secondary oocyte. this secondary oocyte is haploid in nature and this would again undergo another meiotic division to produce 4 haploid daughter cells. One of these is haploid ovum with additional 3 cells which do not get fertilized. these additional haploid daughter oocyte cells are Polar bodies.

Answer:
the amount of genetic variation in a population.
Explanation:
The proportion of the members of a population possessing beneficial allele due to natural selection will increase with time while the proportion of those possessing a harmful allele will decrease with time. After many generations, all the members carrying the harmful allele will die out leaving only those with the beneficial allele. The result is a genetic variation of the population with time.
