Which diagram represents a pair of homologous chromosomes. In males the x and y sex chromosomes are homologs. Occasionally during meiosis a single homologous chromosome pair may fail to separate. 1based on the gene chromosome theory the law of independent assortment assumes that certain genes are.

C 63 in a cell in which 2n 6 the independent assortment of chromosomes during meiosis can by itself give rise to genetically different gametes. The dominant alleles are located on one pair of homologous chromosomes and the recessive alleles are located on another pair of homologous chromosomes. In a karyotype there are 22 pairs of autosomes non sex chromosomes and one pair of sex chromosomes.

Haploid and the chromosomes are each composed of two chromatids. Human cells contain 23 pairs of chromosomes for a total of 46. 25the diagram below represents the four pairs of homologous chromosomes in a cell of a fruit fly before exposure to radiation a and after exposure to radiation b.
