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 geno types and white labels to identify the progeny frequencies.

Equilibrium price will fall and quantity demanded for jelly will also fall

Explanation:

Peanut butter and jelly are consumed together. It means they are complementary goods. These are those goods which are bought together. So increase or decrease in the price of one commodity will automatically affect the demand for another commodity.

When the price of peanut butter increases than people will demand less of peanut butter. Similarly, the demand for jelly is associated directly with the demand for peanut butter. So it will also fall . Due to the fall in the price of jelly and simultaneous fall in demand, the equilibrium price will fall.
