If T represents the allele for tall pea plants and t represents the allele for short pea plants what is the phenotype of each parent and of the offspring?
tall and short
What percent of the offspring will be short around?
60%
Suppose two white flowered pea plants are crossed and produce 1000 offspring how many of those offspring would you expect to have white flowers?
224
What is the phenotypic ratio of the offspring when a tall man marries a short woman?
The phenotypic ratio of the offspring when a tall man marries a short woman is 3:1 (tall/short). The phenotypic ratio is figured by using the punnet square with the dominant allele for tall and the recessive allele for the short gene.
Why did you color the offspring plant a different color than the tall parent plant?
Because the offspring has both the Tall gene and the short gene
If T represents the allele for tall pea plants and t represents the allele for short pea plants what is the phenotype of each parent and of the offspring?
tall and short
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
How many of those offspring would you expect to have white?
1000
If sixteen offspring are produced in the cross shown how many of the offspring from the cross would be expected to have wrinkled yellow peas?
3
Does the eastern cougar have offspring if so how many?
If eastern cougars did not have offspring, they would become extinct. They have one or two at a time.
What percent of the offspring will be short round?
good stuff
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.

What would The combination for female offspring be?
The combination of a female offspring would be XX
If 50 DDdd pairs of parrots mate and each pair has 2 offspring how many of the 100 offspring would you expect of be Dd?

What would happen if the gene for colored spots was not passed from a moth to its offspring?
None of the offspring would have colored spots..
What would the length of eye lashes be to the offspring of a mother with long eye lashes and a father with short eye lashes?
It would depend on the dominant gene: I would compare the mother's parents eyelashes to the father's parents eyelashes, for each of the parent's eyelashes that are long it is an increase in 25% that the offspring will have long eyelashes. Unless half of the father's parents have long lashes then that shows the short lash gene is dominant.
What will have only two possible phenotypes?
Any cross of parents for a single trait where the dominant allele completely masks any expression of the recessive allele as follows:Parents are both heterozygous for the trait. For example Aa X Aa produces 75% of offspring with the dominant phenotype and 25% with the recessive phenotype.One parent is heterozygous for the trait and the other parent is homozygous recessive. For example: Aa X aa produces 50% offspring with the dominant phenotype and 50% offspring with the recessive phenotype.If the trait is co-dominant/non-dominant a heterozygote would have the median characteristic and a homozygote could be either of two phenotypes. If T is tall and t is short the Tt offspring would bemedium in this example. The way to produce offspring with only two phenotypes would be to cross a heterozygous parent with a homozygous parent. For Example:Tt X tt cross would produce 50% tt (short) offspring and 50% Tt (medium) offspring. A TT X Tt cross would produce 50% TT (tall) offspring and 50% Tt (medium) offspring.
