AP BIOLOGY

Detailed explanation-1: -Thus, the future baby has a total of 46 chromosomes. Meiosis allows a species that reproduces sexually.

Detailed explanation-2: -Zygote is formed due to the fusion of male and female gametes. Gametes are haploid cells. Thus fusion of two haploid cells results in the formation of a diploid cell. Therefore zygote is a diploid cell with 46 chromosomes.

Detailed explanation-3: -The number of chromosomes in the gamete is haploid and human gametes contain 23 chromosomes. As zygote is from the fusion of two gametes, the chromosome number is diploid and is double of that in gamete and thus has 46 chromosomes.

Detailed explanation-4: -The zygote is endowed with genes from two parents, and thus it is diploid (carrying two sets of chromosomes). The joining of haploid gametes to produce a diploid zygote is a common feature in the sexual reproduction of all organisms except bacteria.

Detailed explanation-5: -Gametes are the cells responsible for reproduction and creating new humans to continue the species. Gametes are produced through meiosis which means each gamete has only 23 chromosomes. This makes sense also. This way when two gametes fuse together to make a new child you will have 46 chromosomes.
