How does an offspring receive chromosomes from mother and father?

Answer and explanation

Correct answer: Half come from mother and half from father

The governing principle is sexual reproduction and chromosome inheritance. The mother’s ovum and the father’s sperm are haploid, so each contributes 23 chromosomes. At fertilisation, 23 + 23 = 46 chromosomes in the zygote, giving the offspring one set from each parent. Therefore option C is correct. Options A and B wrongly assign the entire set to one parent, and food does not supply chromosomes.
