Assuming a diallelic gene, and considering that Heter0zyg0us individuals carry both the dominant and the recessive alleles, option A is the correct Punnett square that represents the proposed cross.

What is a Punnett square?

The Punnett square is a graphic representation that shows the different types of gamete combinations according to the alleles involved in a cross.

Punnett square shows the probabilities of getting offspring with different genotypes and their consequent phenotypes.

What is a heter0zyg0us individual?

The heter0zyg0us individual is the one that carries different alleles for the same gene ⇒ Dominant allele and recessive allele

Let us say that the color of flowers is determined by a single diallelic gene.

  • F is the dominant allele
  • f is the recessive allele

Cross: Between two heter0zyg0us individuals

Parentals) Ff  x   Ff

Gametes) F  f   F  f

Punnett square)    F      f

                     F     FF     Ff

                     f      Ff      ff

F1) 1/4 = 25% of the progeny is expected to be h0m0zyg0us dominant

    2/4 = 50% of the progeny is expected to be heter0zyg0us

    1/4 = 25% of the progeny is expected to be h0m0zyg0us recessive

The correct Punnett square is A.
