All right, welcome to this video here and i want us to be very careful when we try to analyze this complementarity in genes, right? so first of, we know that according to this data here, that one project of two mutants show normal phenotype, right? when a phenotype is normal, it means that patterns have mutations in different genes, okay? which means that hybrid will get a normal copy of both genes from the parent.
00:40
But then if progeny of two mutants show mutant phenotype, then it means that the parents had mutations imply on the same gene.

For instance, look here, if you look at 1 -4 -5, 1 -4 -5 and 5, and also 1 -4 -5, and also 1 -1 -1 -4 -5, and also 1 -1.
01:06
4 and 5 okay you can see that they do not complement each other except the other other the genes okay so every every every you know these combinations here do not complement each other you can see we do not have complementarity okay except for the others okay so we have so we have one, four, and five not complementing each other.
01:52
Okay.
01:55
And then if we move on to the next one, look at two.
02:01
Okay, look at twos...
