A carrier would have to by heterozygous. Carriers don't express the "carried" allele but have it nevertheless. This means it has to have one allele of each. For example, if a trait has alleles A (dominant) and a (recessive), the heterozygous genotype will be Aa and will display the dominant phenotype (unless the trait is a special/more complex type of expression like incomplete dominance).
Yy is a heterozygous genotype. Homozygous would be YY or yy.
The probability of offspring for two heterozygous dogs (Aa x Aa) is 25% homozygous dominant (AA), 50% heterozygous (Aa), and 25% homozygous recessive (aa) based on Mendelian genetics principles.

Heterozygous
Their genotype would be Tt for Tay-Sachs, with one copy of the normal gene (T) and one copy of the mutated gene (t).
heterozygous
homozygous- TT; heterozygous- Tt :)
Yy is a heterozygous genotype. Homozygous would be YY or yy.
Yes - Hh is heterozygous. HH is homozygous, and hh is homozygous.
Homozygous
The probability is 50%. There are four probabilities: dominant homozygous, recessive homozygous, or heterozygous.
AA could be either homozygous or heterozygous, depending on whether the individual inherited the same allele (A) from both parents (homozygous) or different alleles (Aa) from each parent (heterozygous).
A cross between two individuals that are homozygous for different alleles will only produce heterozygous offspring. This is because each parent can only donate one type of allele, resulting in all offspring being heterozygous for that particular gene.
