Responses
Both are examples of heterozygous genotypes.
Both are examples of heterozygous genotypes.
Both are expressed as a short phenotype.
Both are expressed as a short phenotype.
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 examples of heterozygous genotypes.
Neither of the genotypes TT and Tt are examples of homozygous genotypes. They are both examples of heterozygous genotypes.
The correct response is: Both are expressed as a tall phenotype.
To determine this, we need to understand the concept of genotype and phenotype. Genotype refers to the genetic makeup of an organism, specifically the combination of alleles it possesses for a particular gene. In this case, the gene is responsible for determining plant height.
The genotypes TT and Tt represent different combinations of alleles for the plant height gene. In both cases, the allele for tall height (represented by "T") is present. This means that both genotypes have at least one allele for tall height and can potentially express a tall phenotype.
On the other hand, if an individual has the genotype tt (with both alleles for short height), it would express a short phenotype.
Therefore, both the TT and Tt genotypes are similar in that they have the potential to express the tall phenotype.
