Following Mendelian Genetics, the offspring would always look like one of the two parental varieties. This is due to one allele, having complete dominance over the other. This results in heterozygotes having the same phenotype as the homozygous dominants.
In shorthorn cattle, coat color may be red (RR), white (rr), or roan (Rr). Roan is a phenotype expressed as a mixture of red and white hairs. What mode of inheritance is coat color in short horn cattle?
If you cross roan cows together to produce 12 calves. how many of each phenotype do you expect?
