Use all of the probabilities of getting one green and two yellow seeds in the bunch.
So:
G, Y, Y = 1/4 X 3/4 X 3/4 = 9/64
Y, G, Y = 3/4 X 1/4 X 3/4 = 9/64
Y, Y, G = 3/4 X 3/4 X 1/4 = 9/64
Add all the probabilities together.
9/64 + 9/64 + 9/64 = 27/64.
27/64 is the probability that three F2 seeds chosen at random will include one green seed and two yellow seeds.

How could the botanist best determine whether the genotype of the green-pod plant is homozygous or heterozygous?
The botanist could perform test crosses between the green-pod plant and a known homozygous recessive individual. If all offspring show the dominant green pod trait, the green-pod plant is likely homozygous. If the offspring display a mix of green and yellow pods, the green-pod plant is most likely heterozygous.
What did mendel predict was the probability of producing a tal plant from a genetic cross of two hybrid tall piants?
Mendel predicted a 3:1 ratio for producing a tall plant from a genetic cross of two hybrid tall plants. This means that there is a 75% probability of producing a tall plant and a 25% probability of producing a short plant.
A testcross on a tall pea plant produces only tall offspring. What is the genotype of the tall pea plant?
Tt
What offspring is produced if a heterozygous n tall pea plant is crossed with a homozygousfor this trait what percent of the offspring will be heterozygous?
If a heterozygous tall pea plant, Aa, is crossed with a homozygous plant, AA, for the trait, you will have a one in one in four chance of the offspring being heterozygous. You will need to create a square and plug the traits in to see what the odds are.
How could the f1 generation of tall offspring produce 3 tall plants and 1 short?
An F1 x F1 cross would be a cross between heterozygous (Tt) parents. The offspring would be 1/4 TT, 1/2 Tt, and 1/4 tt. This would mean that 3/4 of the offspring would be tall, and 1/4 would be short.These offspring would be the F2 generation.

In the cross AA x AA what is the probability of obtaining AA offspring?
50% will be tall
If a trihybrid cross for ttggrr x ttggrr is performed what percent of the offspring would be tall green and round?
In a trihybrid cross, the offspring would inherit one allele from each parent for each of the three traits (Tall, green, and round). Since the parents are homozygous for all traits (ttggrr x ttggrr), all the offspring would be tall, green, and round, resulting in 100% of the offspring being tall, green, and round.
5 An F1 plant that is homozygous for shortness is crossed with a heterozygous F1 plant What is the probability that a seed from the cross will produce a tall plant?
there is a 50% chance that the offspring will be tall.
How could the botanist best determine whether the genotype of the green-pod plant is homozygous or heterozygous?
The botanist could perform test crosses between the green-pod plant and a known homozygous recessive individual. If all offspring show the dominant green pod trait, the green-pod plant is likely homozygous. If the offspring display a mix of green and yellow pods, the green-pod plant is most likely heterozygous.
What is Ockra?
A tall tropical Asian annual plant (Abelmoschus esculentus) widely cultivated in warm regions for its edible, mucilaginous green pods.
Will tall plants always have tall offspring?
no. in the second generation it will have a short offspring , but in the first generation it will have tall offspring
In certain plants tall is dominant to short If a heterozygous plant is crossed with a homozygous tall plant what is the probability that the offspring will be short?
0 (there is no chance it will be short since tall is dominant over short). Hope this helps! - Biology Student
What percent of offspring would be tall green and round if a trihybrid cross for TTGGRR x TTGGRR is performed?
100%
If a trihybrid cross for TTGGRRxTTGGRR is preformed what percent of the offspring would be tall green and round?
It does.. But you knew anything you would try to answer it 👏
What did mendel predict was the probability of producing a tal plant from a genetic cross of two hybrid tall piants?
Mendel predicted a 3:1 ratio for producing a tall plant from a genetic cross of two hybrid tall plants. This means that there is a 75% probability of producing a tall plant and a 25% probability of producing a short plant.
If tall peas are crossed with dwarf peas what percent of the peas will be tall in the first generation?
In the first generation of crossing tall peas with dwarf peas, all the offspring will be tall. This is because the tall trait is dominant over the dwarf trait. Each offspring will inherit one tall allele from the tall parent, resulting in all tall offspring.
What is the probability of producing a tall pea plant from genetic cross between two hybrid tall pea plants?
Assuming the gene/allele for a tall plant is dominant and short is recessive this is an impossibility. As in order for both parent plants to be short both chromosomes must contain the t (allele for short) and so the T (allele for tall) cannot be present and will not be passed on to the offspring and it cannot be tall.
