What is the main idea of gene environment interaction?
Gene environment interaction is an influence on the expression of a trait that results from the interplay between genes and the environment. Some traits are strongly influenced by genes, while other traits are strongly influenced by the environment.
Which of the following is an example of phenotype?
Phenotype, all the observable characteristics of an organism that result from the interaction of its genotype (total genetic inheritance) with the environment. Examples of observable characteristics include behaviour, biochemical properties, colour, shape, and size.
What is phenotype and genotype with examples?
A genotype refers to the genetic characteristics of an organism. A phenotype refers to the physical characteristics. For example, having blue eyes (an autosomal recessive trait) is a phenotype; lacking the gene for brown eyes is a genotype.
What are the types of genotype?
A description of the pair of alleles in our DNA is called the genotype. Since there are three different alleles, there are a total of six different genotypes at the human ABO genetic locus. The different possible genotypes are AA, AO, BB, BO, AB, and OO. How are blood types related to the six genotypes?
What are the similarities between genotype and phenotype?
Key Differences (Phenotype vs Genotype)Basis for ComparisonPhenotypeGenotypeChangesPhenotypes might change during the lifetime of an individual like the color of the hair.Genotypes remain the same throughout the life of the individual.9 •

How do you determine a genotype?
Very quick rehash (review): genotype = the genes of an organism; for one specific trait we use two letters to represent the genotype. A capital letter represents the dominant form of a gene (allele), and a lowercase letter is the abbreviation for the recessive form of the gene (allele).
What is the ratio of genotype?
The genotypic ratio describes the number of times a genotype would appear in the offspring after a test cross. For example, a test cross between two organisms with same genotype, Rr, for a heterozygous dominant trait will result in offspring with genotypes: RR, Rr, and rr.
What does AA genotype means?
homozygous dominant
Is AA a good genotype?
AA marries an AA. That’s the best compatible. That way you save your future children the worry about genotype compatibility.
