The gene for petal color in a flower has incomplete dominance, so that individuals with two A1 alleles (A1A1) are black, individ
Verdich [7]

Answer:

The probability of getting a mottled offspring is 0%. There is no A2 allele involved in the cross.

Explanation:

<u>Available data</u>:

  • The gene for petal color in a flower has incomplete dominance
  • Two A1 alleles (A1A1) express black color
  • Two A2 alleles (A2A2) express white color
  • One of each allele (A1A2) express mottled color

In a cross between two black flowers, there is no allele A2, there are just two alleles A1. So, the cross is:

Parental)    A1A1    x    A1A1

Gametes)  A1   A1       A1   A1

Punnet Square)     A1         A1

                   A1    A1A1     A1A1

                   A1     A1A1     A1A1

F1 Phenotypes: 100% black flowers

F1 Genotype: 100% A1A1

There are 0% of probabilities of getting a mottled offspring.
