Question

Plant height in pea plants is controlled by a single gene. T is tall while t is short. Match the genotype on the left with possible progeny on the right. Note you are only given ONE genotype and not a cross. Choose all possible progeny for the genotype on the left.
-Tall or Short or Both
-Short Only
-Tall Only

A. Tt
B. tt
C. TT

Answer 1

Answer:

A. Tt  - Tall or Short or Both

B. tt - Short Only

C. TT- Tall Only

Explanation:

Given -

Height of plant is controlled by a single gene.

"T" represents tall heighted plant while "t" represents short heighted plant

Considering "t" is a recessive allele and "T" is a dominant allele.

Thus,

a) Tall Only means that both the alleles in the genotype would be "TT"

b) Short Only means that both the alleles in the genotype would be "tt"

c) Tall or Short or Both means that the genotype has one "T" and another "t" allele, represneted by "Tt"

Thus,

A. Tt  - Tall or Short or Both

B. tt - Short Only

C. TT- Tall Only
