Hello student, in this question we're asked to identify which of the following events is caused by which mutation.
00:07
So first is semi -sterility.
00:13
Semi -sterility is caused by translocation.
00:18
What happens here is that there is an exchange of genetic material between two non -homologous chromosomes.
00:39
This is known as translocation.
00:47
This translocation results in non -functional gametes and functional -functional gametes which produces 50 % non -functional and 50 % functional.
01:19
Hence it is said to be semi -sterile.
01:22
Next, lethality.
01:28
Lethality is oftentimes very dangerous or we can say lethal.
01:38
This is the result of deletion of the genes which are essential for growth and development.
02:00
So if such genes...
02:03
Next, vulnerability to mutation.
02:12
This can be caused by inversion or deletion or duplication because all these three what they do is that they result in the change in nucleotide sequence and this change can result to mutation.
02:44
Next, altered genetic map.
02:51
Altered genetic map is also caused either due to deletion, duplication or deletion...
