What does a Punnett Square do?

• tell you exactly what your offspring will look like

• increase the chance you pass on recessive traits

• predicts the possible offspring of crosses between different genotypes

• have no purpose but for Taylor to give us extra assignments

Which of the following is homozygous dominant?

• Jj
• Rr
• MM
• ee
