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). phenotype = the physical appearance of a trait in an organism.
What letter represents phenotype?
The “W” and the “B” would be subscripts because they are the phenotypes, or physical representations, of the fur coat’s color.
What is an example of a phenotype?
Examples of phenotypes include height, wing length, and hair color. Phenotypes also include observable characteristics that can be measured in the laboratory, such as levels of hormones or blood cells.
Is blue eyes a genotype or phenotype?
Finally, the genotype of an organism with two recessive alleles is called homozygous recessive. In the eye color example, this genotype is written bb. Of these three genotypes, only bb, the homozygous recessive genotype, will produce a phenotype of blue eyes.
What’s genotype and phenotype examples?
For example, two mice that look virtually identical could have different genotypes. But if they have visibly different traits – say, one has white fur and the other has black fur – then they have different phenotypes.
How do you determine 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 a phenotype in layman’s terms?
The phenotype of an organism is the whole set of characters (or traits) of that organism. It does not mean just ‘what you can see on the surface’. Rather, it means anything which can be made visible by suitable means. For example, blood groups are definitely a part of the phenotype.
