yY
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.
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.
YY
It seems like "YY guy guy" may be a typo or miscommunication. Can you provide more context or clarify what you are referring to?
No, Yy is not a phenotype. Yy represents genotypes, specifically the alleles an individual inherits for a particular gene. Phenotypes are the physical characteristics or traits that result from the interaction of an organism's genotype with its environment.
Yy is a heterozygous genotype. Homozygous would be YY or yy.

Make two punnett squares- one for Yy x YY and one for rr x RR the possible outcomes for Yy x YY are: YY Yy the only outcome for rr x RR is Rr. so the gametes of the two could be either YY Rr or Yy Rr
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.
here is an example: lets say you are crossing yy * Yy.. first separate the letters (they are called alleles by the way) so for yy --> you have y and y for Yy--> you have Y and y For the first gene yy --> put each corresponding letter on top as shown in the picture.. so horizontally. Now do the same thing for Yy but this time vertically. Then in the corresponding boxes combine the letters and there u have it
the answer is one!! (1) apex

Yy Do People Like Gymnastics ? Wa A Stupid Question ! Yy Do Uu Lik Chocolate Yy Do Uu Like Watching Tv Yy Do Uu Like To Read ! Uu Enjoy It Duhh ! Gymnastics Is A Way Of Life For People Nat Jusd A Sport But There Lives !]
