Question

1. give the correct genotype for the description below. use the letters t & t, where t = tall and t = short.

a. homozygous recessive ____\tf. heterozygous tall ____

b. hybrid __\tg. purebred recessive ____

c. short ____\th. homozygous dominant ____

d. homozygous tall ____\ti. heterozygous ____

e. purebred dominant ____\tj. homozygous short ____

Explanation:

Part a: Homozygous recessive

Step1: Recall genotype terms

Homozygous means same alleles, recessive allele is \( t \). So two \( t \) alleles.

Step2: Determine genotype

Genotype is \( tt \).

Step1: Recall hybrid definition

Hybrid (heterozygous) has one dominant (\( T \)) and one recessive (\( t \)) allele.

Step2: Determine genotype

Genotype is \( Tt \).

Step1: Recall trait expression

Short is recessive trait, so needs two recessive alleles (\( t \)).

Step2: Determine genotype

Genotype is \( tt \).

Answer:

\( tt \)

Part b: Hybrid
