Crossing a recessive trait with a dominant trait involves breeding an organism that expresses the dominant phenotype with one that expresses the recessive phenotype. In genetics, the dominant trait will typically mask the expression of the recessive trait in the offspring. This can help determine the genotype of the dominant organism; if any offspring exhibit the recessive trait, the dominant parent must carry a recessive allele. This type of cross is often used in Mendelian genetics to study inheritance patterns.
There is a 50% chance of a homozygous dominant and a 50% chance of a heterozygous.

dominant-appears in first generation recessive-seems to dissapear
A dominant alle masks the expression of the recessive trait in a heterozygous genotype, a recessive allele is the phenotpye expressed is the recessive trait.
The homozygous dominant individual can only pass on the dominant allele and the homozygous recessive individual can only pass on the recessive allele, therefore all offspring will be heterozygous and have the dominant phenotype.
There is a 50% chance of a homozygous dominant and a 50% chance of a heterozygous.
Alleles can be dominant or recessive

Dominant traits are the traits that mask the recessive traits. The dominant traits are stronger than recessive!
If you have 2 dominant alleles, the gene will be dominant, if you have 2 recessive alleles, the gene will be recessive. But if you have 1 recessive and 1 dominant, the Dominant allele will mask the recessive one.
A recessive trait cannot be dominant over a dominant trait. Dominant traits are always expressed over recessive traits in heterozygous individuals because they mask the expression of the recessive trait.

In a situation where both a dominant and recessive allele are present in a gene pair, the dominant allele will be expressed phenotypically. The presence of a dominant allele overrides the expression of the recessive allele.
If the cat is suspected to be heterozygous for a recessive trait, the presumed genotype would be Aa, where A represents the dominant allele and a represents the recessive allele. This means the cat has one dominant allele and one recessive allele for the trait in question. The test cross would involve crossing this cat with a homozygous recessive individual to determine the genotype of the cat.
