Explain the process of sex determination in human beings. what will be the second of the child if an X chromosome carrying a permanent fusee with an egg cell carrying X chromosome?

The process of sex determination in humans - and other higher animals - depends on the presence of sex chromosomes X and Y, also called sexual determinants.

Explanation:

In humans, phenotypic sex is established through the association of the sex chromosomes provided by the father and mother.

Each gamete contains only one chromosome of the sexual pair, X or Y. At the time of fertilization, when sperm and ovum are joined, the fusion of both gametes will produce male (XY) or female (XX) individuals.

A child containing a permanently fused X chromosome to an X chromosome will be of the female sex.

step 1: nitrogen fixation- conversion of atmospheric no₂ into forms useful to plants by lightning, bacteria, and cyanobacteria.

step 2: nitrification-process of converting ammonia to nitrite or nitrate.

step 3: assimilation-plant roots absorb new form of nitrogen.

step 4: ammonification-conversion of organic nitrogen to ammonia by bacteria involved in decomposition.

step 5: denitrification-bacteria turns the decomposed matter back into n₂o, which is released into atmosphere; repeat cycle.
