WHEN YOU CROSS A GREEN SKINNED WATERMELON AND A MUTATED STRIPED WATERMELON, 50% ARE STRIPED AND THE OTHER HALF IS GREEN. IS THE STRIPED TRAIT DOMINANT OR RECESSIVE?
*
green pod=dominant
PHENOTYPE # Offsprings
GREEN PODS- 9
YELLOW PODS- 3
What percent have green pods?
What is the genotype of yellow pods?
What are possible genotypes of offsprings with green pods?

What are the parent's genotypes? How do you know?
*
A pet store's customers prefer pet mice with black fur over white fur. The owner crossed a female black fur with a male black fur. She was surprised 2 c that 3/10 offsprings were white. She didn't know the parents were heterozygous for fur color.

(choices same as above)

Answer 1

Your question requires more knowledge of science and genetics than I have. However, since you haven't received much help with it I thought I would give you a couple of sites. Try these - they may be of some help to you. Sorry I couldn't help more.

Answer 2

Sorry, I don't know. I feel so dumb for not knowing. Is this what they teach in highschool now?

Answer 3

I have no idea. sorry.
