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" typically refers to a genetic code for a specific trait, where "Y" represents a dominant allele and "y" represents a recessive allele. In terms of individuals, the presence of "Yy" would mean that they have one dominant allele and one recessive allele for that particular trait.
yY
Genotype is the underlying genetic makeup of an organism, while phenotype is the observable characteristics resulting from the interaction of genotype with the environment. The process by which genotype becomes expressed as phenotype is called gene expression, which involves the activation of specific genes to produce proteins and other molecules that determine physical traits. This process is complex and can be influenced by environmental factors and other regulatory mechanisms.
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.
A dominant Allele is written YY or Homo dominant. That is completely dominant and no recessive. Yy is half or hetro dominant. Forgive me for it has been a while since i talked and brushed on this. Homo recessive is yy. You should and would never see yY. it is written Yy.
