It appears you are discussing the genetics of pea plants, specifically focusing on the alleles for height (tall vs. short). Let's clarify the terminology and the genetic concepts you're referring to:
-
Alleles: These are different forms of a gene. For height in pea plants, it seems we're dealing with two alleles:
- Dominant allele (capital T) that represents tall plants.
- Recessive allele (lowercase t) that represents short plants.
-
Genotypes: This term describes the genetic makeup of an organism regarding a particular trait.
- Homozygous dominant: TT (tall phenotype)
- Heterozygous: Tt (tall phenotype)
- Homozygous recessive: tt (short phenotype)
-
Phenotypes: This term describes the observable characteristics of an organism.
- If a plant has phenotypes for height:
- Tall: can be either TT or Tt (both genotypes result in a tall phenotype).
- Short: tt (only this genotype results in a short phenotype).
- If a plant has phenotypes for height:
Summary
- The phenotype for height is:
- Tall with genotype TT or Tt.
- Short with genotype tt.
Example Statement
- "A pea plant with the genotype TT or Tt will have a tall phenotype, while a pea plant with the genotype tt will have a short phenotype."
