Transcript

00:01 Not to answer this question, let's talk about inheritance.

00:04 Here you have this.

00:05 And it says, engoses the synthesis of red pigment that is here is by two steps in a pathway as follows.

00:11 You have the colorless intermediate and you need the dominant p, it means either the homocygous dominant or the heterocygoyles in order to produce a magenta that is here, the magenta intermediate.

00:25 If you have the homocygosegous dominant for q or the heterocygidocytes for q, you're going to get red pigment.

00:33 And if you have the homocycle gresissive here, you're going to inhibit this pathway and hence your ghost is going to be colorless or white.

00:43 And the same here.

00:44 The homocycolysisisive is going to be, it's going to inhibit this pathway and you're going to get magenta.

00:49 So it says, what could the phenotype of a plant homocycles for a null mutation of gimp? so in this case, you have the homocyclosyclysis for p.

01:00 So it means that you're not going to.

01:01 To produce this intermediate and your goals is going to remain like, it's going to remain colorless.

01:07 So the answer for question a is white or colorless.

01:12 Question b says, what would a phenotype b of a plant homocycle for a null mutation of gene q? it means you have the homocycolysis for q here and this is going to be magenta because you're going to produce magenta, but it is not going to be able to produce because you have the homocygolysis excessive here.

01:30 So you have here magenta.

01:33 Question.

01:33 Question c says, what would the phenotype b of a plant homocycle for null mutations of genes p and q? it means that if you have the homocycle decisive p here and the homocycle decisive q here, then you're going to have colorless because it doesn't matter if you have the homocycle excessive q here because if you have the homocyclosoc decisive for p here, you're directly going to produce colorless.

01:57 Okay, so you have white, white or colorless.

02:00 Then you have option b.

02:06 That says, it says write the genotypes of the three strains in parts a, b, and c.

02:15 So we have to write here the genotype of them.

02:19 So in this case, for question a, it says, a plan homocygals for a non -mutation of gmp.

02:24 So you have here this.

02:28 Because they are not telling us the genotype for the q.

02:34 So in this case, you can have either this or this, or this, because you're directly going to have white, because you have the homocyglysisis for p.

02:47 And once you can have the heterocylus, okay, because it says that the plant is homocygose for a non -mutation of a gmp.

03:00 So you have a non -mutation here, and they are not telling you that youotype for the q, so you can have this, this, or this.

03:07 So this is the answer for question a.

03:09 Question b, magenta, it says a phenotype of a plant, homocygote for a non -mutation of gene q.

03:14 It means that you have in this case the dominant p and the greciative q or the heterocygous p and the greciative q.

03:34 So this is what you have here.

03:35 Then you have in question c they were telling you that you have the homozyglysisive for both of them.

03:40 So you have this possibility.

03:44 So this is the answer for question d.

03:46 Question e says what if 2 is expected from crossing plants from parts a and b? so, if they are telling you, if they are telling us that, that it means that practically the only possible, or the only possibility for a should be this one here.

04:04 Okay, because if you have three possibilities, then you're not going to be able to solve question e...
