Vedclass · Answer

(D) In a mammal,most body cells are diploid $(2n = 40)$. The seminiferous tubules contain various types of cells: $1$. Spermatogonia (diploid,$2n = 40$) which undergo mitosis. $2$. Primary spermatocytes (diploid,$2n = 40$) which undergo meiosis $I$. $3$. Secondary spermatocytes (haploid,$n = 20$) which undergo meiosis $II$. $4$. Spermatids and spermatozoa (haploid,$n = 20$). Since the seminiferous tubule contains both diploid cells (spermatogonia and primary spermatocytes) and haploid cells (secondary spermatocytes,spermatids,and sperms),some cells will have $40$ chromosomes and others will have $20$ chromosomes.

If the number of chromosomes in most body cells of a mammal is $40$,the cells in the seminiferous tubule will have
