So according to concept of genetics, every character or every trait is controlled by a one gene or multiple genes.
00:13
So in order for a gene to be expressed, it is expressed by a pair of alleles.
00:22
Alleles are two sets of gene counterparts.
00:28
In order for a gene to be expressed, it is expressed by two alleles.
00:32
For example, the trait tall is expressed by a pair of alleles which is tt.
00:41
So if both the alleles are dominant, it is called as a dominant trait.
00:49
If one of the allele is recessive, it is called as heterozygous dominant.
00:58
If both the alleles are recessive, then the character will not be taught.
01:06
It will be short so it will be called as a recessive trait so if in case both the characters which means the capital t and small t the heterozygous will express a new trait so if the heterozygous it becomes medium length of the plant so capital t capital t both dominant refers to a tall trade if both recessive occurs it is a short rate if a heterozygous occurs then the height will be medium so if the expression of the two alleles are equal then it is called as option a for the seventh question it is called as codominence which means both the characters are equally expressed so for question number seven option a co -dominance is the correct answer similarly let's take the second question question...
