In our society a woman is often blamed for not bearing male child. Do you thing it is right? Justify. |
|
Answer» All human beings have 23 pairs of chromosomes. Human males have 22 pairs of autosomes and contain one or two types of sex chromosome. They are either X or Y. On the contrary, human females have 22 pairs of autosomes and contain only the X sex chromosome. The sex of an individual is determined by the type of the male gamete (X or Y), which fuses with the X chromosome of the female. If the fertilizing sperm is X, then the baby will be a girl and if it is Y, then the baby will be a boy. Hence, it is incorrect to blame a woman for the gender of the child. |

(a) How many spermatozoa are formed from one secondary spermatocyte? (b) Where does the first cleavage division of zygote take place? |
|
Answer» (a) A primary spermatocyte completes the fisrt meiotic division (reduction division) leading to formation of two equal, haploid cells called secondary spermatocytes (n=23 chromosomes each). The secondary spermatocytes undergo the second meiotic division to produce four equal, haploid spermatids (n)., ecah spermatids produce spermatazoa. (b) The mitotic division called cleavage starts 30 h after fertilisation when as to the zygote moves through the isthmus the Fallopin tube (oviduct) towards the uterus and forms blastomeres. |
