The question states that yellow fur is dominant over white fur. Given that the alleles for these two traits are a capital Y and a lowercase y, the genotype for the heterozygous cat would be 'Yy' and the genotype for the white cat would be 'yy' since white fur is recessive.

Therefore, if you cross a 'Yy' with a 'yy' the only two genotypes you would get from the punnett square would be 'Yy' and 'yy'.

The only way you would be able to attain a genotype of 'YY' would be if both cats were heterozygous.

Thank you.
