Answer #1

Haploid chromosome is produced in gametes by meiosis and it has only one chromosomes in their cell.

Diploid chromosome in contrast has two set of chromosomes in a single cell and it is produced by mitosis.

Homologous chromosome are pair of chromosomes that are similar in size and length, centromere location with same position for loci of genes and one chromosome is from maternal origin and the another is from paternal origin.

Crossing over between homologous chromosomes during meiosis I, independent assortment of chromatids during meiosis II, reduction of chromosome number to haploid after meiosis II and final fertilization of gametes produced after meiosis causes genetic variation.
