Describe how you might analyze a pedigree to determine whether a particular condition is recessive or dominant, and X-linked or autosomal. For the sake of this question, ignore conditions such as multiple alleles, incomplete dominance, and other complications
What will be an ideal response?
If two nonaffected persons have a child with this condition, it must be a recessive gene that causes the condition. If nonaffected parents have a male child with the condition, it may be X-linked, but with the small sample size, this cannot be proven. If these same parents have a female child without the condition, it still cannot be proven.
