The single gene trait for eye color in human is symbolized as letter b.
00:07
Capital b, dominant allele, lower b, the recessive allele.
00:11
Now, only in the homozygars, recessive condition, will the individual have blue eyes.
00:17
Brown eyes result from having one dominant allele.
00:20
So we know that capital b, brown eyes, and lower b, recessive, blue eyes.
00:28
So in this case, b stand for genotype.
00:33
And the color of eyes phenotype.
00:42
So the question says that the two individuals, heterozygars for both cases are crossed, all the possible genotype seen offspring.
00:53
So now we're talking about the letters.
00:56
So the heterozygars individual, they all have the same genotype, two alleles, capital b, lower b.
01:04
Humans are diploid, so obviously there are two alleles.
01:07
When we call someone heterozygars, that means the two alleles are different, one dominant, one recessive.
01:14
So this individual will show a brown -eye phenotype, which is dominant phenotype...
