MaRussiya [10]

Answer:

A) Chromosomes are made of DNA

C) Alleles are the different forms of a gene that can exist

D) Chromosomes contain genes that control the inheritance of traits.

Explanation:

Chromosomes are long molecules of deoxyribonucleic acid (DNA) that contain part (or all) of the genetic material of an organism. Humans contain 46 chromosomes organized in 23 pairs of homologous chromosomes (22 pairs of autosomal chromosomes and one pair of sex chromosomes, X and Y). Moreover, a gene is a physical segment of a chromosome that contains the information to encode a protein. Alleles are different forms of a gene  (i.e., gene variants) that may be caused by mutations or genetic recombination. Humans are diploid organisms (2N: 46), and therefore we have two copies of each gene (alleles), one on each homologous chromosome.
