This Punnett square shows the crossing of two heterozygous plants with red flowers. R = dominant red, r = recessive white

Question

The Punnett square is a chart used to predict an results of a genetic cross It is used to determine the probability of the occurrence of each genotype among offspring. The Punnett square shows every possible combination for a specific cross of maternal and paternal genotypes.
Drop target 1
Drop target 2
Drop target 3
Drop target 4
Drop target 5

Answer 1

Based on your description of a Punnett square for two heterozygous plants with red flowers (Rr x Rr), here’s how it would typically look and what you can derive from it:

1. Punnett Square Layout:

   • The top of the square would have the alleles from one parent (R and r).
   • The side of the square would have the alleles from the other parent (also R and r).

   Here’s the structure:

   | | R | r | |-----|-----|-----| | R | RR | Rr | | r | Rr | rr |

2. Genotype Outcomes:

   • RR (homozygous dominant): 1 square = 25%
   • Rr (heterozygous): 2 squares = 50%
   • rr (homozygous recessive): 1 square = 25%

3. Phenotype Ratios:

   • 3 red-flowered plants (RR and Rr) to 1 white-flowered plant (rr)
   • This corresponds to a ratio of 75% red flowers and 25% white flowers.
