Addison White · Answer 1

The black cat is the dominant allele B and the white cat is a recessive allele w. now,

in f1: the dominant allele masked the recessive characters but they are heterologous dominant ie BBww

in f2: Bw x Bw

the outcome is BB, Bw, Bw, ww

tip:do the checkerboard formula by mendel it always works
