Question

different types of gametes are produced by human males and females. Explain the types of gametes produced.

Answer 1

Answer:

Gametes are an organism's reproductive cells. They are also referred to as sex cells. The different types of Gametes are explained below.

Explanation:

Gametes exist as an organism's reproductive cells. They are also known as sex cells. Female gametes are named ova or egg cells, and male gametes are named sperm. Gametes exist in haploid cells, and each cell holds only one copy of each chromosome.

• Isogamy: gametes with identical morphology i.e., size and form. This situation is also learned as ‘heterogamy’. These types of gametes are not classified as ‘male’ or ‘female’. These gametes are described as ‘+’ or’-‘.
• Anisogamy: gametes with different morphology i.e. size and shape. These types of gametes are organized as ‘female’ and ‘male’. The gamete with a smaller size exists known as sperm or male gamete whereas the gamete with a bigger size is known as ova or egg or female gamete. Similarly, these gametes can be motile as well as non-motile.
• Oogamy: in humans and mammals, one of the gametes, the male gamete or sperm, exists motile and the other gamete, egg, or female gamete is non-motile. This situation is known as oogamy, wherein a large non-motile egg is fertilized or will fuse with a small and motile sperm to create the zygote.

These are the different types of gametes are produced by human males and females.

Answer 2

Answer:

In humans, males produce sperms, and females, ovum (pl. ova)

Explanation:

As we already know. gametes are the functional units of the reproductive system, which go on to fertilize, form zygotes, and grow into humans.
Females produce ova (egg cells), and males produce sperms. They're usually haploid, i.e., have 1 pair of chromosomes each.

Humans (and mammals, in general) follow the process of oogamy, where the male gamete is motile, and the female gamete, non-motile. The sperm swims to the ovum and fertilizes it to form a zygote.

There are other kinds of reproductive gametes -

• Isogamy - both gametes are morphologically identical, and don't have a sex distinction (they're marked as '+' and '-').
• Anisogamy - both gametes are morphologically distinct and have a sex distinction. Here, they can be motile or non-motile.
