Explanation:
A chromosome is a structure that is made of a chemical known as deoxyribonucleic acid, or DNA as well as protein. Chromosomes are found in the nucleus of cells. Chromosomes contain many genes.
A gene is a molecular unit of heredity. Each gene codes for a polypeptide, which becomes a protein that performs a function in a living thing. The DNA molecules are very long and in order to fit inside the nucleus of a cell, they are highly coiled and condensed. During sexual reproduction, one haploid set of chromosomes is given to the offspring from each parent, forming a diploid amount of chromosomes in the offspring.
Since chromosomes contain all of our genes, an organism that reproduces sexually gets a combination of genes from both parents. Genes that are expressed produce an organism's phenotype.

Preservation stands for preserving or sustaining what already exists. aimed at preserving natural resources in their original environment, free from human interference.

Answer:

I believe the developing Sertoli cells are responsible for influencing the development of male reproductive structures through the production of anti-mullerian hormone. During embryonic development there is a sexually indifferent stage in which the embryo has the potential to develop either male or female structures. The sertoli cells produce Mullerian inhibiting substance, a peptide hormone that causes the mullerian ducts to regress.
