MS-LS3-2 Punnett Squares

If a pea plant were homozygous recessive for height, how would its alleles be represented?

• TT
• Tt
• tt
• tT

Recessive alleles may not be expressed because they are

• masked by a dominant allele
• the least common allele in a population.
• the most common allele in a population.
• less likely to have crossing over.
