6 Modern Theories on Genetics and Gender Determination–Explained!

Asia
Different Modern Theories those are Essential for Sex Determination are: 1. Chromosomal theory: Sex of the individual depends on the behaviour of particular chromosome. The chromosomal mechanism of sex determination varies in different organisms. a) XY-Method: In this method of sex determination both the sexes have got even number of chromosomes but female is homogametic having XX chromosomes while, male is heterogametic having XY. The female produces eggs with X chromosomes and male produces sperms of two kinds X and Y. images.slideplayer.com ADVERTISEMENTS: Drosophila has rod like chromosome X and its unlike met with hook at its end is Y (Sex chromosome) in male.The rest chro­mosome i.e. 3 pairs (two V shaped or one dotted pair) which do not show sexual differences are called autosomes. b) ZW method: It is…

Mutation-Definition, Major Classes, and Types-Discussed!

Mendelian segregation never produces new character but re­sults in only redistribution of genes.Darwin was aware of these sudden changes and called ‘sports’ while Bateson described as ‘discontinuous variation’ and stated that they were of general oc­currence.Hugo DeVries (1901) gave the name ‘mutation‘ to these sud­den discrete changes. He worked on evening Primerose plant (Oenothera lamarkiana). i.ytimg.com ADVERTISEMENTS: Mutation may be defined as sudden heritable change in a gene due to change in sequence of nucleiotides which alter the phenotype of an individual, e.g. Short legged sheep was discov­ered by English farmer Wright (1791). Morgan (1910) studied mutation in Drosophila and reported white eyed mutant in red eyed flies. Major classes: 1. Chromosomal aberration- Change in structure and number of chromosomes. 2.
