Hello everyone, the question is to find the genotype of christopher and phenotype of each individual.
00:08
Here it is a autosomal recessive as it affects the both sexes.
00:14
Let us consider a, capital a as the straight hair gene and the small a as the curly hair gene.
00:23
Therefore, the homocygous small a is a genotype of the curly hair and the heterocious.
00:30
That is capital a and small a, capital a and capital a or the genotype of the straight hair gene.
00:41
This is the given pedigree analysis chart and here the geoges must be a heterozygous straight hair because as his children are affected with the same and the michael sandra may be a heterozygous straight hair or the homozygous.
01:00
But here we are taking the homozygous straight hair gene as none of her descendants have the curly hair.
01:08
Similarly, the tina and christopher may be a homozygous straight hair or the heterozygous straight hair.
01:17
Now let us see a phenotype of each individual.
01:21
Here, the george having a heterozygous that is straight hair phenotype.
01:29
Next, arlene has a homozygous curly hair.
01:34
Phenotype is curly...
