Hello students and this question number one we have given that in garden piece the genes of tall plant that is dominant over the dwarf so in the 8 part of question number one we have to tell what will be the appearance of f1 so here the answer for this question will be the tollness this is represented by the genotype both capital t and the dwarfness this is represented by the genotype both small t when the homozygous tall t which is both capital t this is crossed with homocygous recessor which is both small t then we get in the f1 t and small t in f1 generation all will be tall so the answer for first a part is that in the f1 we get capital t small t both all are tall in the f1 we get capital t small t both all are tall in the f1 generation.
01:16
Now in the b part of first question we have to tell the appearance of f2.
01:23
So when the t and t they are self crossed, then we get capital t small t, capital d small t, we get capital d both and capital t small t, capital t small t and both small t.
01:41
When we perform this cross in a quinnet square then we get this result.
01:47
So there is three tall ratio one dwarf plants.
01:58
So this is the answer for the b part, that three tall and one dwarf.
02:05
So this is the illustration for b part.
02:09
Now in the c part, we have to tell the appearance of the offsprings of a corrosion of the f1 with its tall pairing.
02:18
So answer for the c part will be when the offsprings of the f1, which are t and small.
02:24
T.
02:26
They get crossed with the homozygous parent which is both capital t.
02:31
Then we get, let's perform this cross in a bonnet square.
02:40
Capital t small t and for homozygous parent both capital t.
02:45
Then both capital capital capital and small both capital capital and small.
02:51
So we get this that all are tall plants...
