use the punnett square to predict the phenotype of the offspring if a plant heterozygous for yellow seeds is crossed with a plant homozygous for green seeds?

Respuesta :

From the question, yellow is dominant to green.

So the parents are yellow (Yy) and green (yy)

Cross Yy  x yy

Punnet square (I can't put lines):

        Y      y

y      Yy     yy

y      Yy     yy

Phenotypes:

Yy: yellow

yy: green

So you'd see 1/2 yellow and 1/2 green

A square representation of monohybrid or dihybrid crosses between two parents and their generations is called Punnett square. It tells about the phenotypic and genotypic characters of the progenies.

50% progenies will have yellow colour while other 50% will have green colour seeds.

Punnett square for the cross :

Given,

  • Dominant yellow heterozygous allele = Yy
  • Recessive purebred green allele = yy

See the cross in the attached image below.

Yellow coloured seed progenies have genotype of Yy while green coloured seeds have yy recessive genes.

Phenotype ratio = 1 (yellow) : 1 (green)

Therefore, 50% is yellow and the other is 50% is green.
