A red furred cow mates with a white furred bull and all the F1 offspring are red. This shows:

1. Every member of the F1 generation shows only one of the two parental colours. 2. That means the red allele has completely masked the white one, which is complete dominance. 3. Red is therefore the dominant gene and white the recessive gene. 4. Incomplete dominance, also called partial dominance, would blend the two into an intermediate colour instead. 5. Codominance would express both parental colours in the offspring, and multiple allelism means a gene exists in more than two allelic forms. _Source: NECTA CSEE 2022 Biology 033, Question 1: Multiple Choice Items, item (iv)_
