Okay, i want to answer this question.
00:01
Let's talk about inheritance.
00:03
This question says, red kernel color with results from the presence of at least one dominant elite at each of four independently segregated genes.
00:12
So when you have the dominant r and the dominant b at least one of them, you're going to get red kernel.
00:21
So we're going to represent this like this because this plan can be another r, another dominant r allel or aggressive an allele and the same here, a dominant b or aggressiveive b.
00:31
So it says, kernels on double homocybalogly recessive plants are white.
00:37
So when you have this, they're going to get white kernel.
00:46
And then it says, and the genotypes like this, and also like this, i'm going to code for brown kernels.
01:04
Brown kernels.
01:06
Okay, so it says if a true breeding red kernel plant, it means a true breeding, red kernel plant is going to be homozygos for both genitals.
01:14
Genes and is crossed with a true breathing white kernel plant, it means with this plant here, you're going to get in the f1 that all the offspring are going to be like this, okay? hydrocygo for r and hittalasego for b.
01:35
Because practically, you don't even make a fundamental square, but for example, the only gamete here that you're going to produce is this gamete and the possible gamete here is going to be like this.
01:46
So you are going to cross this with this, you're going to fuse them and you're going to get okay, so let's answer the question.
01:52
It says, what is the expected genotype for the f1 generation? and this is the expected genotype for the f1 generation, okay? it says, what are the expected genotypes and phenotypes for the f2 generation? okay, so you have to, to make a type hybrid pattern in the square.
02:08
In order to make f2 generation, we have to cross 2f1 off -print.
02:13
So you're going to cross this.
02:17
Okay, and how you're going to calculate the gametes? well, the gametes, you're going to find by mixing this r or each of these are allelels with each of this b alleles.
02:27
So the gametes, as they have the same, you know, the gamins are going to be the same for this and for this parent.
02:31
So you're going to get here this, this.
02:38
So let's make or let's set a die -high every parent in the square that is going to be like this.
03:02
And you're going to get here a double homo -sigo -familat, for example, homo -segos -a -4 -b, hitios -ego -r, hit -trosago for r, heterososobel for b, hittlosago for this, hit -hittlosago for b, d, d, d, hit threshold here.
03:17
Fomo segoleener fomosigo gecisi.
03:19
Hit gosgo for r.
03:26
Homosgogo for r.
03:27
Homo segouggel for r.
03:28
Hit gergfecdggfecd for v.
03:31
Fomosgoggfecd for r.
03:33
Fomosgogfecccd for r.
03:34
Hit crossagos for r.
03:35
Hitro cycles for r.
03:39
Hitro signals for r.
03:42
Hgggggggggfzze.
03:46
Fomoggffeccccc for r.
03:47
Hitr.
03:48
Hitr.
03:49
Formal syracis for r and quoseuiocese for me.
03:52
So this is going to be your panel, okay? they are asking you for the expected genotypes and phenotypes.
03:58
So all of them are going to be like your, well, let's say all the genotypes that you're going to find here.
04:06
So you're going to get this genotype, for example, that is rrbb, you only find one of them that is this one here.
04:18
Only one.
04:19
Okay, so let's not even circle this.
04:21
Because this is the only one.
04:23
And then you have homo -scygoyal for r and heterosexual for b.
04:28
How many of them you find? you find one.
04:32
Let's make it like this.
04:34
You find one...
