One more example. Let’s mate Mr Spock (of the recessive pointy ears) instead
to his frequent human admirer, Nurse Chapel, who has two normal alleles.
Sadly, the little guys have no chance of pointy ears now.
To sum it up, Mr Spock and Nurse Chapel have 100% round eared babies, while
Mr Spock and Jax have 50% round and 50% pointed ear babies. Ahh, the mystery
of romance, motherhood, and genetics
