A
both alleles for the individual are identical (BB or bb)
4

8
Q
what is a dominant allele
A
an allele that is expressed when an individual carries 2 different alleles for a given gene (the outcome gene)
9
Q

A
an allele that is not expressed when an individual carries 2 different alleles for a given gene (the allele that is in the genetic information, but isn’t shown)
