Question

a plant tt for tall height is crossed with a plant tt for short height. the offspring have the genotype tt. what is the phenotype of the plant? tall height short height tt tt

Explanation:

Step1: Understand dominant - recessive traits

In genetics, if 'T' represents the allele for tall height (dominant) and 't' represents the allele for short height (recessive).

Step2: Determine the genotype of offspring

When a plant with genotype TT (homozygous dominant for tall height) is crossed with a plant with genotype tt (homozygous recessive for short height), all offspring have the genotype Tt.

Step3: Identify the phenotype

Since the presence of the dominant 'T' allele masks the recessive 't' allele, the phenotype of the plants with genotype Tt is tall height.

Answer:

tall height
