“The chromosome number of the sexually reproducing parents and their
offspring is the same". Justify this statement.
Answers
Answer:
During fertilisation, the fusion of male and female gametes takes place, which results in the number of chromosomes in the zygote to be equal to that of somatic cells. Thus, the chromosomal number of the sexually producing parents and their offspring is the same.
Explanation:
Answer:
See the explanation.
Explanation:
A chromosome is a tread-like structure of nucleic acids and protein present in the nucleus of the most living cell, carrying genetic information in the form of genes.
Each species has a fixed number of sex chromosomes in them.
As we know that the number of chromosomes gets halved during gamete formation. Therefore the number of sex chromosomes in gametes is half the number of any normal chromosomes of a cell.
During fertilization, the half number of sex chromosomes take part in fertilization, so, half of the chromosomes from both the parents fuse to form the total number of chromosomes in the offspring.
Therefore, the chromosome number of sexually reproducing parents and their offspring is the same.
