What is the genotypic ratio here

• TT = 25% Tt= 50% tt=25%
• all tall
• TT= 75% tt = 25%
• Tt = 100%

The dominant trait is

• yellow pea seeds
• green pea seeds
• there is no dominant seed
• Jolly green giant

To express the recessive trait you must be

• homozygous dominant
• heterozygous
• alleleerific
• homozygous recessive

A Punnet Square will 

• tell you exactly what your offspring will look like
• increase the chance you pass on recessive traits
• predict genotypes and phenotypes in offspring
• have no purpose but for Taylor to give us extra assignments
