In this question, it was given egg with 22 chromosome and it fertilized with normal sperm cell.
00:18
So, egg consists of 22 plus xx chromosome and male generally consists of 22 plus x or 22 plus y chromosome.
00:42
So, either x will fertilize with the x or either y will fertilize with the x.
00:49
As per question, this x is not given.
00:54
This xx is missing or is not present.
00:58
Only 22 are given in the question.
01:03
So this means two chromosomes are missing, xx chromosomes are missing and when such situation occurs is known as monosomy.
01:13
So what happens in this 22 when they fertilized, when fertilization takes place either this will will participate or either this will participate.
01:29
So it will form 22 plus 22, this 22 plus x or y.
01:38
We will write here as x because this is missing.
01:41
So it would be 45 chromosomes...
