Question

write a brief note on sex determination in human bieng

Answer 1

HELLO MATE!
sex-determination system is a biological system that determines the development of sexual characteristics in an organism. Most organisms that create their offspring using sexual reproduction have two sexes. Occasionally, there are hermaphrodites in place of one or both sexes. There are also some species that are only one sex due to parthenogenesis, the act of a female reproducing without fertilization.

In many species, sex determination is genetic: males and females have different alleles or even different genes that specify their sexual morphology. In animals this is often accompanied by chromosomal differences, generally through combinations of XY, ZW, XO, ZO chromosomes, or haplodiploidy. The sexual differentiation is generally triggered by a main gene (a "sex locus"), with a multitude of other genes following in a domino effect.

In other cases, sex of a fetus is determined by environmental variables (such as temperature). The details of some sex-determination systems are not yet fully understood. Hopes for future fetal biological system analysis include complete-reproduction-system initialized signals that can be measured during pregnancies to more accurately determine whether a determined sex of a fetus is male, or female. Such analysis of biological systems could also signal whether the fetus is hermaphrodite, which includes total or partial of both male and female reproduction organs.

sex determination is illegal in our country but still many parents practice this illegaled activity.
parents generally do this to know whether the baby is boy or a girl so that if the baby is a girl they can foeticide .
Many people in our society still have narrow minded thinking which need to be stopped immediately.
sometimes doctors and nurses are involved in this type of activity to earn money .
so if we get to know about this kind of activity we should immediately inform to the police
.
