Question

what information can be deduced from a pedigree?
select the two answers that are correct.
□ the probability of a female being a carrier of an x - linked allele
□ how an x - linked trait is passed down over generations
□ the probability of a parent or grandparent being infertile
□ how autosomal traits contribute to x - linked traits
□ the probability that y - chromosome analysis will prove paternity

Explanation:

Pedigrees track trait inheritance across generations. They allow calculation of carrier probabilities (e.g., for X-linked traits in females) and show transmission patterns of X-linked traits over family lines. Infertility, autosomal contribution to X-linked traits, and Y-chromosome paternity probability are not deducible from standard pedigrees focused on trait inheritance.

Answer:

A. the probability of a female being a carrier of an X-linked allele, B. how an X-linked trait is passed down over generations
