What is the significance of formation of special lineage of cells during sexual reproduction?
Answers
Answer:
The process of meiosis produces unique reproductive cells called gametes, which have half the number of chromosomes as the parent cell. Fertilization, the fusion of haploid gametes from two individuals, restores the diploid condition. Thus, sexually reproducing organisms alternate between haploid and diploid stages.

Answer:Maintainance of constant number of chromosomes of species
Explanation:
One of the characteristic feature of the species is " all the members of species have same numer or chromosomes".
Somatic cells of the body is diploid i.e have two sets of chromosomes (In humans diploid condition is 46 chromosomes out of them 23 is from mother and 23 from father.)
and these cell divide by mitosis inorder to restore the cells after they die to ageing and division of cells during the healing of injury.
During the formation of gametes they undergoes the process of meiosis so the sperms and egg produced are haploid in nature i.e they contain 23 chromosomes and during fertilisation again diploid condition is restored.
