What do you mean by crossing over during meiosis? Is this the reason of variations in child?
Asked by Ritwika Sharma | 6th Jan, 2013, 07:13: AM
Crossing over is the exchange of genes between homologous chromosomes, resulting in a mixture of parental characteristics in offspring. crossing over moves sections of DNA between homologous chromosomes and allows for independent assortment. This process allows recombination of genes between homologous chromosomes. This alters the linkage between genes on the same chromosome. This is one of the reasons for variations in the offspring.
