Question

If a pea plant’s alleles for height are tt, what is true of its parents?(1 point)
Responses

Both parents were tall.
Both parents were tall.

Both parents were short.
Both parents were short.

Both parents contributed (passed on) a recessive allele.
Both parents contributed (passed on) a recessive allele.

Both parents contributed (passed on) a dominant allele.

Answer 1

If a pea plant's alleles for height are tt, it means that the plant is homozygous recessive for height. This indicates that both parents must have contributed a recessive allele (t) for the offspring to express the recessive trait (short height). Therefore, the correct response is:

**Both parents contributed (passed on) a recessive allele.**
