Question

In humans, attached earlobes are recessive to free hanging earlobs. If two heterozygous free lobed parents mate, what is the chance that they will produce an offspring with attached earlobes? Complete the Punnet Square to show your work!

F = Free hanging earlobes

f = attached earlobes

Answer 1

Bellow I attached the punnet square you need. From it you can see, that the likelihood of producing an offspring with attached earlobes is 25% (ff)
