Se hela listan på study.com A genotype is the genetic blueprint of an individual. It's the internal code that determines how everything is formed. The physical result of the genotype is the phenotype. For example, the For example, the type of earwax you have is determined by a single gene.

Genotype Examples The term just means "the genes a particular organism has." Any example of a genotype would just be a chart of a particular living thing's chromosomes, or DNA molecules responsible for various genetic traits. However, having certain genes does have observable results. For example, children with the genotypes ‘BB’ and ‘Bb’ have brown-eye phenotypes, whereas a child with two blue-eye alleles and the genotype ‘bb’ has blue eyes and a blue-eye phenotype. The phenotype can also be influenced by the environment and sometimes certain alleles will be expressed in some environments but not in others. In simple genotypes, the alleles for only one or a few traits are specified.

If, for example, a child has received one brown-eye allele – represented by ‘B’ – and one blue-eye allele – represented by ‘b’ – then their genotype would be ‘Bb’. A genotype is the actual genetic composition or makeup of an organism.

Biology, Genetics. 42. Image Using the eye color example, this genotype is written BB. We will use a second trait that Mendel investigated, seed color, as an example. Seed color is governed by a single gene with two alleles. The yellow-seed allele is Definitions: phenotype is the constellation of observable traits; genotype is the To consider these in the context of evolutionary biology, we want to know how these One example is epistasis ("standing on") where one loc Alleles are the variants of genes, whereas, the set of genes responsible for certain traits are known as genotypes.

The contrasting terms genotype and phenotype are used to define the characteristics or traits of an organism. The genotype identifies the alleles related to a single trait (e.g. Aa), or to a number of traits (e.g.

“B” is the dominant allele whereas “b” is the recessive allele. Genes are found on chromosomes, those tightly-packed DNA structures in the cell nucleus.
