If two heterozygous plants create four offspring how many do you predict would be tall?
Using a Punnett square, we can predict that 3 out of the 4 offspring will be tall if both parent plants are heterozygous for the tall trait (Tt x Tt). This is based on the 3:1 phenotypic ratio expected from a monohybrid cross.
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.

When two pea plants with TT genotypes are crossed-bred how many short tt plants will there be in the new generation?
In the offspring generation from crossing two pea plants with TT genotypes, all the offspring will have the genotype Tt. However, all of these offspring will be tall since the tall trait is dominant (T) over the short trait (t). Therefore, there will be no short tt plants in the new generation.
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.
What must be true for a cross between a tall plant and a short plant to produce any short plants?
Both the tall plant and short plant must be heterozygous for the height trait, meaning they each carry one dominant and one recessive allele. When they produce offspring, there is a 25% chance of obtaining a short plant by inheriting two recessive alleles for the height trait.
When model crossed true-breeding tall plants with true-breeding short plants all of the offspring were tall because?
Homozygous for tall is TT Homozygous for short is tt All F1 offspring from this cross are Tt which makes them genotypically heterozygous and phenotypically tall.
If two heterozygous plants create four offspring how many do you predict would be tall?
Using a Punnett square, we can predict that 3 out of the 4 offspring will be tall if both parent plants are heterozygous for the tall trait (Tt x Tt). This is based on the 3:1 phenotypic ratio expected from a monohybrid cross.
You perform a test cross on a tall pea plant half the offspring are short what conclusion can you draw from this outcome?
The genotype of the tall pea plant is heterozygous
What letters can be used to model Mendels cross of true-breeding tall plants what true-breeding short plants in a Punnett square?
TT for the homozygous tall parent, tt for the homozygous short parent and Tt for the heterozygous offspring.
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 a certain species plant the allele for tallness is dominant over the allele for shortness.to determine wether a tall plant is heterozygous should be crossed with a?
To determine whether a tall plant is heterozygous, it should be crossed with a homozygous recessive plant (short plant). If any offspring are short, the tall plant must be heterozygous; if all offspring are tall, the tall plant is likely homozygous dominant. This test cross allows for the observation of inheritance patterns in the offspring.
When two pea plants with TT genotypes are crossed-bred how many short tt plants will there be in the new generation?
In the offspring generation from crossing two pea plants with TT genotypes, all the offspring will have the genotype Tt. However, all of these offspring will be tall since the tall trait is dominant (T) over the short trait (t). Therefore, there will be no short tt plants in the new generation.
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.
If you made a Punnett square showing Gregor Mendels cross between true breeding short plsntd the square would show that the offspring had what?
The Punnett square would show that all offspring would be heterozygous for the trait, meaning they would have one allele for tall plants and one allele for short plants. This would result in all offspring being tall plants phenotypically, but carrying the allele for short plants.
What must true for a cross between a tall plant and a short plant to produce any short plants?
the tall plant must be heterozygous.
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.
What must br true for a cross between a tall plant and a short plant to produce any short plants?
The tall plant must be heterozygous.
