Relate Genotypes and Phenotypes Quick Check 4 of 54 of 5 Items Question How are the plant height genotypes TT and Tt similar?(1 point) Responses Both are examples of heterozygous genotypes. Both are examples of heterozygous genotypes. Both are expressed as a tall phenotype. Both are expressed as a tall phenotype. Both are examples of homozygous genotypes. Both are examples of homozygous genotypes. Both are expressed as a short phenotype.
Both are expressed as a tall phenotype.
The plant height genotypes TT and Tt are similar in that they are both expressed as a tall phenotype.
To determine how the plant height genotypes TT and Tt are similar, we need to understand genotypes and phenotypes.
Genotype refers to the combination of alleles present in an organism's DNA for a particular trait. In this case, we are looking at the plant height trait, which is controlled by the T gene.
The T gene has two possible alleles: T (representing the tall phenotype) and t (representing the short phenotype).
The genotype TT means that the organism has two copies of the T allele, making it homozygous dominant for the tall trait.
On the other hand, the genotype Tt means that the organism has one copy of the T allele and one copy of the t allele, making it heterozygous for the trait.
Now, relating it back to the question, the similarities between TT and Tt are:
1. Both are examples of genotypes: This is true for both TT and Tt since they represent different combinations of alleles for the plant height trait.
2. Both are expressed as a tall phenotype: This is only true for TT, as it is homozygous dominant and will always express the tall phenotype. Tt, however, is heterozygous and can express either the tall or short phenotype, depending on the dominance relationship between the alleles.
Therefore, the correct response is: Both are examples of genotypes.
