Answer: The correct answer is B) 23 in males.

In human beings, 23rd pair of chromosome, which is also called sex chromosomes is different amongst males.

It is XY in males whereas it is same in females that is XX.

23rd is the only homologous pair that is different in males as the presence of Y chromosomes determines the male sex. Chromosome pair 1- 22 are same in both males and females and are called autosomes.

What are the possible consequences if only one egg is implanted
tensa zangetsu [6.8K]
  <span>are we talking human reproduction? in this case only 1 egg is implanted. in unusual cases there could be 2 eggs implanted meaning fraternal twins. if 1 egg splits, we get identical twins. with only one egg implanted, there is only 1 kid being produced. 

the female has eggs stored from birth. 1 ovary 'pops' once a month to either be discarded via a period or implanted after fertilization. multiple eggs released is usually the effect of fertility drugs making many eggs get released at once. this is unusual unless fertility drugs are in use</span>
