A student has two dominant traits dependent on single genes

A student has two dominant traits dependent on single genes, cataract (an eye abnormality), which he inherited from his mother, and polydactyly (extra fingers and/or toes), which he inherited from his father. If the loci for these two traits are very closely linked, would the student\'s child be more likely to have:

a.) either cataract or polydactyly?

b.) Both cataract and polydactyly

c.) Neither trait?

EXPLAIN your answers

Solution

a.) either cataract or polydactyly
