Question

Q. What is sex determination ? State
the different methods of sex determination in
animals.​

Answer 1

Answer

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.

Answer 2

$let\:p(y)= {y}^{3}- 2{y}^{3} - 9y+ 18$

$one\: factor = y - 3$

$divide \: p ( y ) by ( y -3)$

$y-3) {y}^{3} - 2 {y}^{2} - 9y + 18( {y}^{2}+y-6$

$_____ {y}^{3} - 3 {y}^{2}$
