Vedclass · Answer

(C) In humans,the sex chromosome constitution of a female is $44 + XX$. During oogenesis,the primary oocyte undergoes meiosis to form a secondary oocyte and a polar body. The secondary oocyte is released during ovulation. Since the female has only $X$ chromosomes,the ovum produced after meiosis will always contain $22$ autosomes and one $X$ chromosome. Therefore,a freshly released human ovum contains one $X$ chromosome.
