crossed. What are the genotypes of the offspring?

Answer:

Explanation:

With two hetero-zygous are crossed,

Phenotypes are generally 75% of the dominant (Green) and 25% of the recessive (Yellow).

Genotypes would be

25% homo-zygous dominant (Green)

50% hetero-zygous  (Green)

25% homo-zygous (Yellow)

Note that the words homo-zygous and hetero-zygous do NOT spell with a hyphen.  Brainly filter does not allow for the correct spelling.

When two heterozygous (Gg) individuals mate, the expected genotypes in offspring are GG, Gg and gg in proportion 1:2:1.

  • Complete dominance refers to the genetic phenomenon in which the expression of the dominant allele masks the expression of the recessive allele in hetoroyigous individuals.

  • In this case, both parents are heterozygous (genotype Gg) for the trait pea plant color.

  • In consequence, both parents can produce two types of gametes: 'G' gametes (50%) and 'g' gametes (50%).

The Punnett square for this cross is:

          G               g

G     1/4 GG    1/4 Gg

g      1/4 Gg    1/4 gg

In conclusion, when two heterozygous (Gg) individuals mate, the expected genotypes in offspring are GG, Gg and gg in proportion 1:2:1.
