Quick Answer: Do males produce gametes?

Do males and females produce gametes?

Most people think of the gonads as the male testicles. But both sexes have gonads: In females the gonads are the ovaries, which make female gametes (eggs). The male gonads make male gametes (sperm).

What produces gametes in a man?

Gametes are formed through meiosis (reduction division), in which a germ cell undergoes two fissions, resulting in the production of four gametes. During fertilization, male and female gametes fuse, producing a diploid (i.e., containing paired chromosomes) zygote.

How are gametes produced?

Gametes are produced by mitosis (not meiosis) and after fertilization a diploid zygote is created. … It can only divide by meiosis to produce haploid cells once more, which then produce the main adult body.

Why do men produce two gametes?

Animals with two different sex chromosomes are of heterogametic sex, and they are thus able to produce two types of gametes. … In humans (as well as many other animals), males generally have one X and one Y chromosome, while females have two X chromosomes.

Do males produce more gametes than females?

Females generally produce a few but large gametes, whereas males produce large numbers of much smaller gametes. … Consequently, the limited number of gametes and the greater parental investment of the females result in an asymmetry in the degree of sexual selection between the two sexes.

What is a male gamete?

Gametes are an organism’s reproductive cells. They are also referred to as sex cells. Female gametes are called ova or egg cells, and male gametes are called sperm. … Each sperm cell, or spermatozoon, is small and motile.

How are sperm cells made?

Sperm develop in the testicles within a system of tiny tubes called the seminiferous tubules. At birth, these tubules contain simple round cells. During puberty, testosterone and other hormones cause these cells to transform into sperm cells.
