Vedclass · Answer

(A) In humans,the diploid number of chromosomes in a somatic cell is $46$ ($44$ autosomes + $2$ sex chromosomes).During oogenesis,meiosis occurs,which reduces the chromosome number by half.Therefore,an unfertilized egg (female gamete) contains $23$ chromosomes in total.These $23$ chromosomes consist of $22$ autosomes and $1$ sex chromosome ($X$ chromosome).Thus,the correct composition is $22$ autosomes and $1$ sex chromosome.
