Question

Can someone help me with punnett squares? Biology

Imagine that you are crossing two plants that are heterozygous for flower color and seed shape. The dominant and recessive alleles for these traits are:
purple flowers: P
white flowers: p
round seeds: R
wrinkled seeds: r


Genotype of parent plant 1: PPRR
Genotype of parent plant 2: pprr

How will the alleles for these traits assort into the gametes that each parent might produce?

Parent plant 1: PPRR

Gamete 1: PR
Gamete 2: PR
Gamete 3: PR
Gamete 4: PR

Parent plant 2: pprr

Gamete 1: pr
Gamete 2: pr
Gamete 3: pr
Gamete 4: pr

Are these answers above correct? How would I fill out this punnett square? (I attached an image)

Answer 1

I know I am super late but I can help other people.

Basically each letter represents a characteristic. For this P=purple flowers, p=white flowers, R = round seeds, and r = wrinkled seeds.

Using the information above we can make the Punnett square which shows what the genetic makeup will look like for the generation for each offspring.

I hope this helped!

Answer 2

i did this in ms paint.... see if you can draw it out using this example.
