A pedigree is shown below for a disease that is autosomal dominant. The genetic makeup of the first generation is
1 AA and Aa
2 Aa and aa
3 Aa and AA
4 Aa and Aa
Explanation:
Both the parents are heterozygous as the diseaese is autosomal dominant.

The recessive genes located on X-chromosome in humans are always
1 Expressed in males
2 Sub-lethal
3 Lethal
4 Expressed in females
Explanation:
The recessive genes located on the X-chromosome in humans are always expressed in females, because they have two of them and therefore, can be homozygous or heterozygous for any locus on this chromosome. On the other hand, males are hemizygous for the X chromosome, because they have only one copy of every gene on the X chromosome.

Pedigree chart is used to identify:
1 Genetic drift
2 Genetic diversity
3 Genetic diseases
4 Genetic mutation
Explanation:
Pedigree charts are generally used in families to track genetic diseases and determine the possibility of a child having a disorder in a family.
