In squash, yellow seeds are dominant over green seeds. If two heterozygous yellow seed squash were crossed, what are the genotyp
Umnica [9.8K]

Answer:

The result of cross two squashes with yellow seeds is an offspring of squash with green seeds -dominant caracter- heterozygous and yellow seeds squashes in a genotype proportion 1:2:1  and phenotype proportion 3:1

Explanation:

The cross of two heterozygous individuals for a characteristic results in an offspring that will have both characteristics in pure and heterozygous form. It is a cross monohybrid which complies with the principle of independent segregation exposed by Mendel.

For the characteristic "seed color" the green color would be G and yellow represented as g.

At the cross of two heterozygous squashs:

- Parents: Gg X Gg

- <u>Punnett's Square</u>:

Alleles    G         g

G           GG       Gg

g           Gg        gg

Offspring:

  • A pumpkin of green seeds GG (25%)
  • Two pumpkins of green heterozygous seeds Gg (50%)
  • One pumpkin of yellow seeds gg (25%)

Genotype proportion 1:2:1

Phenotype proportion 3:1
