9) The allele for polydactyly is dominant, but most individuals do not exhibit the polydactyly
trait. Which of the following explains why this occurs in nature? a) The allele for polydactyly is
completely penetrant b) The allele for polydactyly is never expressed c) The allele for
polydactyly is incompletely penetrant d) The allele for polydactyly is variably expressive e)
None of these is an adequate explanation 1) Which of the following is not a reason why human
genetics is more complicated than plant genetics? a) genetic analysis of human traits relies on
family records b) it is not ethical to set up controlled human matiogs to observe progeny c)
humans produce more progeny than plants d) humans produce many fewer progeny than plants
e) some genetic conditions do not manifest themselves until middle age or beyond.
