Organisms need sex cells, or gametes, to facilitate sexual reproduction, which promotes genetic diversity. During fertilization, male and female gametes merge to form a zygote, combining genetic material from both parents. This genetic variation enhances adaptability and survival in changing environments. Additionally, sexual reproduction can help eliminate harmful mutations over generations.
The genotype of the organism must be tt, because sex cells (gametes) only carry one allele each. When gametes carrying the same allele combine during fertilization, the resulting genotype is homozygous for that allele. In this case, if all sex cells have the t allele, the organism's genotype is tt.
Generally two sex cells i. e. the male gamete combines with the egg to form the zygote that develops into a new organism (embryo).
Another word for sex cells is gametes. A male and female gamete come together to form a zygote: the first cell of the new organism.

This is important because two sex cells become fertilized and join together to form the new organism. If sex cells had the same number of chromosomes as body cells, then offspring would have twice as many chromosomes as a normal animal would.

The two kinds of sex cells that a gametophyte produces are eggs (female sex cells) and sperm (male sex cells). During sexual reproduction, these sex cells fuse to form a zygote, which develops into a new organism.
Mutations in sex cells can be passed on to children. Mutations in sex cells only affect offspring. Mutations in sex cells do not affect the organism.

Sex cells have 1/2 the number of chromosomes of a normal cell (23)

Cells are actually the elemental constituents of body who unite together to form tissues and these later unite to form an organ, then organism. So it can be said that cells are building blocks of human body. The cells can be haploids or diploids and they form chromosomes. the Chromosomes can be either sex linked chromosomes or non sex linked chromosomes. These cells undergo cell division process either through "MITOSIS" or "MEIOSIS" to form chromosomes. Depending upon there linkage as sex or non-sex they help in determining the genotype and phenotype of the organism. Thus we see that it's the cells that determine the genotype or the genetic constituent of the organism and also the phenotype or the physical characteristics of the organism.
