c. What are homologous chromosomes, and why are they important in meiosis?
Meiosis which occurs in organisms that reproduce sexually, results in the production of haploid cells known as gametes. In animal cells, the male gamete is the sperm cell and the female gamete is the egg cell. In plants, it is virtually the same thing. Pollen grains give rise to sperm cells and ovules contain egg cells. Homologous chromosomes are a similar pair of chromosomes of approximately the same size and length. One member of the pair comes from the mother, the other from the father. During meiosis, homologous chromosomes undergo synapsis and crossing over takes place. This results in a recombination of genes in unique ways that will end up in the gametes or sex cells of an organism.
