Hello students here the question is about the pedigree.
00:03
So in the given pedigree it has been seen that the trait is inheritant as dominant trait and affected phenotype may be homozygous dominant or heterozygous dominant these two.
00:22
So the normal phenotype is recessive this is a this is normal and this is affected.
00:33
First generation is individual 1 1 generation 1 individual 1.
00:41
So we can say that generation 1 individual 1.
00:54
So for this individual 1 is affected does may have genotype capital a or small a.
01:00
She is married to a normal individual with genotype small a small a.
01:03
If she has genotype capital a capital a then all offspring should be affected.
01:08
So however some of our offspring are normal so this indicates individual 1 1 has heterozygous genotype aa.
01:14
So the genotype is aa because some of our offspring are normal.
01:19
So this indicates individual 1 has heterozygous genotype because if she has genotype capital a capital a then all offspring should be affected.
01:26
Number b number b is generation 1 individual 2 for that individual 1 2 is normal because the answer is small a small a and here trait passes as a dominant trait.
01:45
Thus the normal trait is recessive so thus individual 1 2 has genotype small a small a...
