Answer: In anaphase 1 of meiosis, a pole may receive either the maternal or paternal homologue for each chromosome pair. This means that the genes on different chromosomes assort independently.
Step-by-step explanation:
1) Anaphase 1: Anaphase 1 is a stage in meiosis, the process of cell division that produces gametes (sperm and eggs) in sexually reproducing organisms. During anaphase 1, homologous chromosomes separate and move towards opposite poles of the cell.
2) Homologous chromosomes: Homologous chromosomes are pairs of chromosomes that have the same genes in the same locations. One chromosome in each pair is inherited from the mother (maternal homologue) and the other from the father (paternal homologue).
3) Independent assortment: Independent assortment is a genetic principle that states that during meiosis, the homologous chromosomes segregate independently of each other. This means that the maternal and paternal homologues of each chromosome pair can randomly line up at the center of the cell and be pulled towards either pole during anaphase 1.
4) Assortment of genes on different chromosomes: The independent assortment of homologous chromosomes during anaphase 1 leads to the random separation of genes on different chromosomes. This means that the genes on different chromosomes can be distributed into gametes in various combinations. As a result, new combinations of genes are created, contributing to genetic diversity.
In summary, in anaphase 1 of meiosis, a pole may receive either the maternal or paternal homologue for each chromosome pair. This allows for the independent assortment of genes on different chromosomes, leading to the creation of new combinations of genes and genetic diversity in the resulting gametes.
