Description : In tobacco plant, the male gametes have twenty four chromosomes. What is the number of chromosomes in the female gamete? What is the number of chromosomes in the zygote? -Biology

Last Answer : The number of chromosome in the female gamete would be same as that in the male gamete, i.e., it will have 24 chromosomes. The number of chromosome in the zygote would be double the number present in the gamete and hence, it would be 48.

Description : Genes are not found in pairs - (1) in body cells (2) in ovary after fertilization (3) in gametes (4) in zygotes

Last Answer : (3) in gametes Explanation: Genes are a part of the chromosome and are found in pairs in somatic cells. One member of the gene pair segregates into a gamete, thus each gamete only carries one member of the gene pair. Gametes unite at random and irrespective of the other gene pairs involved.
