Hello students today we are studying chapter chromosomal basis of inheritance and that we are studying topic mechanism of sex determination now there are heterogomantic male and homogametic female now homogametic means XX where’s heterogametic means XY so let’s say you find out how does this mechanism works. heterogomantic is the term that’s used for chromosome and mechanism of sex determination which has mel who is XY and female who is X X now xx female is Homogametic T whereas XY male is heterogametic. mechanism of sex determination now sex determination in human beings can be concisely said that it’s the father decides the sex of the child now hetero commences is the mechanism of sex determination one sex is hetero gametic that is produced two types of Germans in human beings it is the male whereas another one is homogamy thick it is the female who produces similar garments that’s X and X the X X and X Y type which is the hetero-romantic male produces two spoons whereas the xx XO type petrol gravitates female the exo and XX type is different it can have header gamma dick me whereas the said oh and said said type hetero gametic female produces two kinds of x where 50% others said chromosomes and give him type of chromosomes are something which are very common to this type now fifty percent are without sex chromosome also in certain categories of sex determination so students in this part of the chapter we did study about different mechanisms for sex determination I hope you are very clear in this concept thank you
