This Punnett square shows the results of a Yy x Yy cross to form F2 progeny.

Punnett squares are convenient ways to represent the types and frequencies of gametes and progeny in experimental crosses.

This Punnett square shows the results of a Yy x Yy cross to form F2 progeny.

Use your understanding of Mendel’s law of segregation and the rules of probability to complete the Punnett square for this cross.
First identify the gametes. Use pink labels to identify the male and female gamete types and white labels to identify the gamete frequencies. 

•  Then identify the F2 progeny. Use pink labels to identify the progeny genotypes and white labels to identify the progeny frequencies.
