Question

Spike is not a clone of his father. He inherited DNA from both parents. would chromosomes are condensed units of DNA. f spike has 36 chromosomes, you expect that Spike would have inherited____________ chromosomes from his mother and ________________chromosomes from his father.

Answer 1

18 from mom 18 from dad

Answer 2

Answer is 18 chromosomes from his mother and 18 chromosomes from his father.

Every cell of Spike is diploid, having pair of homologous chromosomes. if he has 36 chromosomes, it means each cell have 18 pair of homologous chromosomes. During fertilization male gamete (haploid) having 18 chromosomes come from his father fuses with egg (haploid ) having 18 chromosomes come from his mother, to form zygote (diploid) having 36 chromosomes or 18 pairs of chromosomes. Zygote develops into individuals.
