Question

If a pea plant's alleles for height are tt, what is true of its parents?

A. Both parents were tall.
2 Pts
B. Both parents were short.
C. Both parents contributed a recessive allele.
А E
D. Both parents contributed a dominant allele.

Answer 1

C.

Reason:

The plant got it's tt alleles from it's parents, so they would have had to have the recessive alleles to pass it down. This does not necessarily mean that the plants were short, though, as parent plants who both had Tt alleles would have had a chance to have an offspring with tt alleles also.

Answer 2

C

Step-by-step explanation:

tt is a recessive allele so it can only be tt if the parents were both tt&tt or Tt&Tt
