dominant and recessive alleles

Question 1

in heterozygous pairing

Answer 1

• allele may be dominant (expressed in offspring)

- allele my be recessive (trait is suppressed in presence of dominant allele)

Question 2

determination

Answer 2

• if one allele is dominant, a homozygous (BB) organism has the same phenotype as a heterozygous organism (Bb)
• for example allele b is recessive, it is suppressed by dominant allele B, however the recessive allele will not be suppressed if the dominant allele is not present
