A
Mutant alleles
3
Q
If a hybrid that inherited a recessive mutation from each of its parents has a mutant phenotype, then the mutations are alleles of the same genes. If the hybrid has a wild phenotype, then the recessive mutations are alleles of______
A
Different genes
4
Q
Most genes encode
A
Polypeptides
5
Q
In homozygous condition, recessive mutations often abolish or diminish_____
A
Polypeptide activity
6
Q

A
Some dominant mutations
7
