John and his mother both have brachydactyly. John and his father both have Huntington disease. Both traits are rare and autosomal dominant. Johb's wife is phenotypically normal and is pregnant. Two-thirds of people who inherit the huntington allele show symptioms by age 50, and brachydactyly is 90% penetrant. Genotyping of the fetus reveals that the fetus has the huntington allele. What is the probability that the child will express both brachydactyly and Huntington disease by age 50 if two genes are 10 m. u. apart

they contain different fossils because life on earth has changed through time.

the fossils in them were formed on the surface of earth due to exposure to sunlight.
