How are the plant height genotypes TT and Tt similar?(1 point)
Responses
Both are examples of heterozygous genotypes.
Both are expressed as a tall phenotype.
Both are examples of homozygous genotypes.
Both are expressed as a short phenotype.
Both are expressed as a tall phenotype.
The correct answer is: Both are expressed as a tall phenotype.
To determine how the plant height genotypes TT and Tt are similar, we need to understand the concept of genotype and phenotype.
Genotype refers to the genetic makeup of an individual, specifically the combination of alleles (forms of a gene) that an individual carries for a particular trait. In this case, the plant height trait is determined by the presence of the T allele (tall) and the t allele (short).
TT is a genotype in which both alleles are the same (homozygous), and both alleles are tall. Tt is a genotype in which there are two different alleles (heterozygous), with one allele being tall (T) and the other being short (t).
While TT and Tt have different genotypes, they share a common characteristic: they both have at least one dominant allele for tallness (T). As a result, both genotypes express the tall phenotype.
Therefore, the correct answer is: Both are expressed as a tall phenotype.
