Question

if animals from the same species mate but the mother has 18 chromosomes per diploid cells and the father has 20 chromosomes per dioploid cell, would the offspring have 19 chromosomes per diploid cell?

Answer 1

Yes, it is likely that the offspring will have 19 chromosomes per diploid cell.

Explanation -

Meiosis is another type of cell division in which the daughter cells are formed from one parent cell. The number of chromosomes in the daughter cell became half the number of chromosome in the parent's cells. This type of cell division takes place in the gametic cells.

Here, diploid number of chromsomes in mother = 18

haploid number if chromosomes in mother's gametes after meiosis = 9

Diploid number of chromsomes in father = 20

haploid number if chromosomes in mother's gametes after meiosis = 10

When fertilisation between the male and female gamete takes place the nucleus of the two gametes haing the chromosome will unite with each other and the final diploid zygote is formed and it will 10+9 chromsomes per diploid cell.
