What else can I help you with?
In a cross between a pea plant with the genotype TT and a pea plant with the genotype Tt percent of the offspring will be Tt.?
false
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
When The dihybrid cross pictured shows how two traits pea shape and pea color are passed. Assume that yellow pea color and smooth peas are the dominant forms of the two traits. If sixteen offspring ar?
nine A+ three
If you cross a purebred smooth pea with a purebred wrinkled pea what percentage of the first generation will be smooth peas?
All the first-generation offspring will be smooth peas, as the smooth trait is dominant over the wrinkled trait in peas. This is known as a monohybrid cross involving one gene with two alleles.
What crosses between two hybrid Tt pea plants?
A cross between two hybrid Tt pea plants would be expected to produce 1/4 TT, 1/2 Tt, and 1/4 tt offspring.
How do you find possible phenotypes in offspring?
The possible genotypes and phenotypes of the offspring can be determined using a Punnett square, a grid that shows the possible combinations of alleles that can result at fertilisation. The Punnett square below shows the expected genotypes of the offspring of parent pea plants that both have the genotype Rr.
WHAT DO THE LETTERS ON INSIDE OF THE PUNNET SQUARE STAND FOR?
Using Punnett Squares, you can predict the genotypes and phenotypes of the offspring of a cross between a homozygous (purebred) tall pea plant and a homozygous (purebred) short pea plant.
What do the letters on the inside of the punnets square stand for?
Using Punnett Squares, you can predict the genotypes and phenotypes of the offspring of a cross between a homozygous (purebred) tall pea plant and a homozygous (purebred) short pea plant.
What do the letters on the inside of the punnet square stands for?
Using Punnett Squares, you can predict the genotypes and phenotypes of the offspring of a cross between a homozygous (purebred) tall pea plant and a homozygous (purebred) short pea plant.
How do you find possible phenotypes of offspring?
Mendel Diagrams. If the offspring gets a dominate gene from both parents, the offspring will exhibit traits from the dominate gene. If the offspring gets a dominate gene from one parent and a recessive gene from another, the offspring will exhibit traits from the dominate gene. If the offspring get a recessive gene from both parents, the offspring will exhibit traits from the recessive gene.
Distinguish between parental and recombinant phenotypes?
Parental Phenotypes are when the offspring of two parents look like one of the two parents. for example, if a green wrinkled pea is crossed with a heterozygous yellow round pea the offspring are 1/4 yellow round, 1/4 green wrinkled, 1/4 yellow wrinkled, and 1/4 green round. the yellow round and green wrinkled look like the parents so they have parental phenotypes, whereas the yellow wrinkled and the green round have combinations of the parental phenotypes thus they have recombinant phenotypes.
Which of the following would be an example of Mendel's classic cross?
An example of Mendel's classic cross would be crossing pea plants that are purebred for tall height with pea plants that are purebred for short height, resulting in a first-generation hybrid offspring that are all tall.
In a cross between a pea plant with the genotype TT and a pea plant with the genotype Tt percent of the offspring will be Tt.?
false
What will have only two possible phenotypes?
A trait determined by a single gene with two alleles will typically have only two possible phenotypes, one associated with each allele. Examples include pea plant seed color (yellow or green) and human blood type (A or B).
When two pea plants with Tt traits are cross-pollinated, what offspring will result?
usually tall
When two pea plants with tt traits are cross pollinate what offspring will result?
usually tall
Suppose that two true breeding pea plants are crossed One of the pea plants always produces yellow pea pods and the other always produces green pea pods If green pea pods are dominant over yellow pe?
If green pea pods are dominant over yellow pea pods, all offspring from the cross will have green pea pods. This is because the dominant trait (green) will mask the recessive trait (yellow) in the heterozygous offspring. The genotype of the offspring will be heterozygous for the pod color trait.
