A pea plant has two dominant alleles for plant height – tall.  We say that this plant is:

• heterozygous dominant.

• heterozygous recessive.

• homozygous dominant.

• homozygous recessive.

A pea plant has two different alleles for flower color: a purple allele (which is dominant) and a white allele (which is recessive).  According to Mendelian genetics, the pea plant will have:

• white flowers.

• purple flowers.

• purple and white petals.

• pale purple flowers.

In one box of a Punnett square, two identical capital letters indicate a gene which is:

• homozygous dominant.

• homozygous recessive.

• heterozygous dominant.

• heterozygous recessive.

• a cell.

• a centromere.

• an allele.

• a nucleus.
