29. 'The chromosomal number of the asexually
producing parents and their offspring is the same.
Justify this statement.​

Answer 1

Answer:

Explanation: In asexually reproducing organisms, only one parent is  

involved. The part of the body which develops into a  

new organism contains cells having the same number  

of chromosomes as any other cell in the body of the  

organism. This separated part develops and forms a  

new organism.

For example, human being somatic cells contain  

46 chromosomes. When gametes are formed, they  

contain half the number i.e., 23 chromosomes but  

when gametes fuse to form the zygote, they maintain  

the 46 chromosomes.

In sexually reproducing organisms, the parents are  

diploid (2N) as each of them is having 2 complete  

sets of chromosomes. They form haploid (N) male  

and female gametes by the process of meiosis. The  

haploid gamete has one set of chromosomes since,  

these gametes fuse during fertilisation and restore the  

original number of chromosomes in the offspring.
