The pedigree chart represents three generations. Red family members have a disease that is caused by an autosomal dominant gene. Consider the chart. The father in Generation I must have what genotype? D represents the allele for the disease; d the allele for normal. A) DD B) Dd C) XDYD D) XDYd

the father have the genotype of Dd.

Explanation:

As the desies is autosomal dominant so their is no involvement of sex chromosome and the presence of any dominant allel on an autosome will cause the desies to occur in the individual. As their are two types of chromosome in individual the sex chromosomes and the autosomes.as the desies is dominant so their will be no skip generation and no carier in the pedigree with the presence of one allel will result in apperance of the desise.The desies is autosomal so the male and female individuals are equally effected.

the generally accepted parts of modern cell theory include: all known living things are made up of one or more cells. all living cells arise from pre-existing cells by division. the cell is the fundamental unit of structure and function in all living organisms.
