Saved In Mendel's initial experiments, he crossed two true-breeding pea plants, one with purple flowers (the dominant trait) and the other with white (the recessive trait). Their offspring, the F? generation, were non-true-breeding with both purple and white flowers. true-breeding with white flowers. true-breeding with white purple flowers. non-true-breeding with white flowers. non-true-breeding with purple flowers.

00:01 Hello everyone so in this particular question we are given that two true breeding pea plants they are crossed with purple flower and white flower so in the case we all know that purple is dominant and white is recessive so suppose we take two true breeding plants that a pea plants one is of purple color so obviously it is true breeding so it will be homozygously dominant that is represented by capital b and one we are going to take white flowers which will be represented with small p right i have changed the color of the white one now they are crossed with the purple flower so purple can be either homozygous one or it could be the heterozygous one but the white flower they will be having both the recessive p so now let's take a cross with the dominant one so this is a case one and this is our case two so in case one if purple is crossed with the first one right if purple is crossed with a homozygously dominant purple so obviously the genotype will be same as that of pairing but if it is crossed we can say that if it is crossed with the heterozygous one then we are going to get all the dominant purple but homozygous as well as the heterozygous condition would be there.

01:35 That means the genotype won't be same.

01:38 And in the case of white, if we are crossing over the purple flowers with the homozygously white one, then also we are going to get a homozygous, a heterozygous purple flowers.

01:51 So in short, we are getting purple one.

01:54 And in the case of white flowers, if we are crossing it with the dominant purple, so we all know that we are going to get the purple flowers in heterozygous condition.

02:07 Right? then we are getting the purple flowers but in heterozygous condition.

02:12 So here it is all purple...
