GENERAL HISTOLOGY

Detailed explanation-1: -Secondary oocytes are the immature ovum which are formed after ovulation and have not undergone fertilisation yet. Thus the correct answer is option (D). Secondary oocytes are haploid in nature.

Detailed explanation-2: -Answer. Answer: ovum as well as primary ooctye as they are haploid as they have only n cells left after meiosis.

Detailed explanation-3: -Secondary oocyte, ova, secondary spermatocyte and spermatids are haploid in number, each with 23 chromosomes.

Detailed explanation-4: -Ootid. An ootid is the haploid result of ootidogenesis. In oogenesis, it doesn’t really have any significance in itself, since it is very similar to the ovum. However, it fills the purpose as the female counterpart of the male spermatid in spermatogenesis.

Detailed explanation-5: -Primary spermatocytes are diploid (2N) cells. After meiosis I, two secondary spermatocytes are formed. Secondary spermatocytes are haploid (N) cells that contain half the number of chromosomes.
