Vedclass · Answer

(D) Klinefelter's syndrome is a chromosomal disorder characterized by an extra $X$ chromosome,resulting in a genotype of $47, XXY$.In a normal human,the diploid number of chromosomes is $46$ ($44 + XX$ or $44 + XY$).$A$ normal sperm provides $23$ chromosomes ($22 + X$ or $22 + Y$).To result in a $47, XXY$ zygote,the ovum must have contributed $24$ chromosomes ($22 + XX$ due to non-disjunction of $X$ chromosomes during meiosis).Therefore,the ovum contained $24$ chromosomes.

What would be the number of chromosomes in the ovum (fertilized by a normal sperm) that resulted in the appearance of Klinefelter's syndrome in the offspring?
