Ответ:
A - 3:1
Explanation:
In order to determine what number of offspring will have attached earlobes, we must make a Punnett table. We know that attached earlobes are the dominant gene, and we know unattached earlobes are recessive.
| P | p
——————-
P | PP | Pp |
——————-
p | Pp | pp |
As we can see, only one out of the four squares has two recessive genes. Therefore, our answer would be A - 3:1.

Only the occurrences of usual odors cannot be described by a number.
