Question

In watermelon the alleles for green color (G) and short shaped (S) are dominate, striped color and long shape are recessive. A plant that is long and striped is crossed with plant that is a heterozygous for both traits. What are the possible genotypes and phenotypes for the offspring?

Answer 1

Answer:Dominant allele for green color:

G

Dominant allele for short shape:

S

Recessive allele for striped color:

g

Recessive allele for long shape:

s

The plant that is long (ss) and striped (gg) is crossed with a plant that is heterozygous for both traits, meaning it carries one dominant allele and one recessive allele for each trait (GgSs).

Now, let's consider the possible combinations of alleles in the offspring:

For color:

The offspring can inherit either the dominant allele (G) or the recessive allele (g) from the heterozygous parent.

For shape:

The offspring can inherit either the dominant allele (S) or the recessive allele (s) from the heterozygous parent.

So, the possible genotypes for the offspring are:

GgSs (green and short)

Ggss (green and long)

ggSs (striped and short)

ggss (striped and long)

And the corresponding phenotypes are:

Green color and short shape

Green color and long shape

Striped color and short shape

Striped color and long shape
