Question

Describe sex cells .

Answer 1

Answer:

Gametes are cells that are produced by meiosis and contain a haploid number of chromosomes. The existence of sex cells in man was discovered in the seventeenth century by Leeuwenhoek and de Graaf, challenging the previous belief that children inherit all traits from fathers only, and that menstrual blood of a woman serves as a lining and uterus as an incubator for embryonic development.

Explanation:

• Education of two types, in the form and function of different, sex cells (gametes) is an adaptation to sexual reproduction whereby the inherited material of the parents is combined.
• The advantage of sexual reproduction is that it produces offspring with new combinations of genes and therefore traits.
• This achieves a great diversity of offspring that allows for better adaptation to changing environmental conditions and the evolution of the living world.
• Adaptation to sexual reproduction has led to the division of all cells in the body into two categories:

body (somatic) cells and

sex cells (gametes).
