The feminine gamete, called the ovum, is nonmotile and reasonably big when compared with the male gamete. Once the male that is haploid feminine gametes unite in a procedure called fertilization, they grow into what exactly is known as a zygote. The zygote is diploid, and therefore it includes two sets of chromosomes.
Sex Chromosomes X-Y
The gametes that are male or semen cells, in people along with other mammals are heterogametic and contain 1 of 2 kinds of intercourse chromosomes. Sperm cells carry either an X or Y intercourse chromosome. Feminine gametes, or eggs, but, have just the X intercourse chromosome as they are homogametic. (more…)
