Apr 28, 2017 · A phenotype is the physical expression of DNA. In contrast, the genotype is the chemical makeup of DNA that causes a particular phenotype. DNA is first transposed into RNA, a slightly different information molecule, which can then be translated into a protein. Phenotypes are caused by the interactions of the many different proteins created by DNA.
Every horse has two copies of the coat colour gene in all of their cells. A horse that has two black coat alleles A has the genotype AA and is homozygous. The phenotype of this horse would be a black coat. In contrast a horse that has one black coat allele A and one chestnut coat allele a would have the genotype Aa and is heterozygous.

Nov 23, 2021 · For example, consider a cross between two plants and a gene that controls the plant height allele. In this example, T is the dominant allele, for tall and t is the recessive allele, for short. So, plants with the genotype TT or Tt are tall. Plants with the genotype tt are short. The phenotypes are tall and short.
2 days ago · Narration. "Phenotype" simply refers to an observable trait. "Pheno" simply means "observe" and comes from the same root as the word "phenomenon". And so it's an observable type of an organism, and it can refer to anything from a common trait, such as height or hair color, to presence or absence of a disease. Frequently, phenotypes are related ...
Apr 20, 2018 · Phenotype is defined as an organism's expressed physical traits. Phenotype is determined by an individual's genotype and expressed genes, random genetic variation, and environmental influences. Examples of an organism's phenotype include traits such as color, height, size, shape, and behavior. Phenotypes of legumes include pod color, pod shape ...
