Genotype Examples
Some of the genotype examples are given below:
- Blood Type: In humans, blood type is determined by the genotype of the ABO gene, which encodes for the A, B, and O blood group alleles. Different combinations of these alleles result in blood types A, B, AB, or O.
- Seed Color in Peas: In Gregor Mendel’s experiments with pea plants, seed color was determined by the genotype of the seed color gene (Y = yellow, y = green). Homozygous dominant (YY) individuals have yellow seeds, while homozygous recessive (yy) individuals have green seeds.
- Fur Color in Mice: In laboratory mice, fur color is controlled by multiple genes, including the Agouti gene. Variations in the genotype of the Agouti gene result in different coat colors, such as agouti, black, or albino.
- Genetic Disorders: Genetic disorders, such as cystic fibrosis and sickle cell anemia, are caused by specific mutations in genes. The genotype of individuals carrying these mutations determines their susceptibility to these disorders and the severity of symptoms.
- Plant Height in Peas: In Mendel’s pea plant experiments, plant height was determined by the genotype of the height gene (T = tall, t = short). Homozygous dominant (TT) individuals are tall, while homozygous recessive (tt) individuals are short.
Genotype
The genotype refers to the genetic makeup or combination of alleles possessed by an organism. Studying the genotype meaning and genotype ratio helps in understanding the inheritance patterns of traits.
In this article, we will cover the genotype meaning, genotype examples and genotype ratio in detail.
