Many genes are involved in coat color and coat patterns in cats. the autosomal dominant white (wd ) allele results in pure-white coat cats while the recessive allele (w) results in colored coat cats. the dominant white (wd ) allele masks all coat colors and coat pattern genes. at another locus, the autosomal tabby gene (t) has multiple alleles and shows the following dominance series: brown-tabby (tb )> brown-striped (ts )> black (t) coat. predict the genotype of the parents based on their f1 offspring from multiple litters. remember to give the genotype of both the white and the tabby genes and use the gene symbols defined in the question.

The parents of the white cat would be a dominant white cat and a recessive colored coat cat.  The parents of the autosomal tabby would be a dominant tabby and either a recessive brown cat, striped cat, or a recessive black cat.

Explanation:

The genotypes and phenotypes would be : WW- Dominant white and ww- recessive color coat cat; their offspring would be 100% recessive white kittens

TT- dominant tabby and a recessive brown cat; their children would be 100%- dominant brown tabby

TT- dominant tabby and a recessive striped cat; children would be 100%- brown striped

TT- dominant tabby and a recessive black cat; children would be 100%- tabby kittens

i think it is true in my reasonment ..
