Question

The chromosome number of the sexually reproducing parents and their offspring is the same justify your answer

Answer 1

The chromosome number of the sexually reproducing parents and their offspring is the same because reproductive cell are haploid(contain halved no. of chromosome)
sperm + ovam = zygote
23 +23 =46

Answer 2

• The chromosomes number of the sexually reproducing parents and their offspring is same.
• As we know, in case of sexual reproduction, the genetic material DNA constitutes both gametes i.e. of male and female.
• These are combined to form the a new cell known as zygote but the no. of chromosome remains the same and doesn't gets doubled.
• This is because gametes contain only half amount of DNA i.e. half number of chromosomes.
• SO, a zygote carries half chromosomes from male and half from female. Therefore, the new cell formed have normal no. of chromosomes.
