In mice the YY genotype is lethal during embryonic development. This means that the mating of heterozygous individuals will produce a ratio of 2:1 Yy to yy offspring.
A 'YY' genotype is homozygous dominant for that particular trait. If it is Yy, it will be heterozygous.

Yy is the what of an individual?
A cross involving only one trait is a ? Cross
What is the process by which genotype becomes expressed as phenotype?
The process by which genotype becomes expressed as phenotype is called recombination. Recombination usually occurs naturally and during meiosis.
What is the penotype of Yy?
yY
How many different allele combinations would be found in the gametes produced by a pea plant whose genotypes are RrYY?
It depends on the allele combinations of the other pea plant parent. If the other pea plant parent also has a genotype of RrYy, then there are 16 combinations. If the other parent has genotype RRYY, then there are only 4 allele combinations. If the other parent has a genotype of RrYY, then there are 8 allele combinations in the gametes. If the other parent has a genotype of RRYy, then there are also 8 possible combinations in the gametes. Finally, if the other parent has the genotype rryy, then there are 4 gamete combinations.
What percent of the offspring will display the recessive trait if parent 1Tt crosses with tt?
Crossing Yy x Yy yields YY, 2Yy, yy. Since Y is dominant over y, then YY and 2 Yy all result in the same phenotype. Therefore 3/4 of the offspring will resemble their parents.
What is the genotype?
YY
Is Yy a phenotype?
No, it is a genotype.
What was the genotype of the plant that produced yellow pea F1 generation?
Yy
Do a punnett square for one parent having AAA and the other having AAA?
For the two given parents: 1 offspring will have the homozygous genotype: YY 1 offspring will have the homozygous genotype: yy 2 offspring will have the heterozygous genotype: Yy
What was the genotype of pea plants that produced green peas in the F2 generation?
yy

What is the genotype of normal human female?

Determine the phenotypes for the genotype yellow body color is dominant to blue?
well it could be yellow for like yy of b
How was it possible that there were short plants in the f2 generation if there werent any short plants in the f1 generation?
The reason why short plants reappeared in Mendel's F2 generation of pea plants was because their short trait was heterozygous. Both parents carriedÊthat recessive gene, so they passed it on to their offspring.
In a certain plant yellow leaves are dominant (Y) and red leaves are recessive (y). A plant with genotype Yy and a plant with YY are crossed. If they have four offspring how many would you predict wou?
the answer is one!! (1) apex
What is the phenotype for YySs?
YY is phenotype Yy is not yy is a phenotype
What is the process by which genotype becomes expressed as phenotype?
