Phenotypic variation can be produced by genetic differences, environmental influences and stochastic developmental events.
What can produce many different phenotypes?
Natural selection can act on traits controlled by many genes
However, in many cases, phenotypes are controlled by multiple genes that each make a small contribution overall result. Such phenotypes are often called polygenic traits, and they typically form a spectrum, taking many slightly different forms.
What are the 3 types of phenotypes?
With one locus and additive effects we have three phenotypic classes: AA, Aa and aa.
What are 3 examples of phenotypes?
- Eye color.
- Hair color.
- Sound of your voice.
- Certain types of disease.
- Size of a bird’s beak.
- Length of a fox’s tail.
- Color of the stripes on a cat.
What is phenotype example?
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.
How many phenotypes are there?
When the gene for one trait exists as only two alleles & the alleles play according to Mendel’s Law of Dominance, there are 3 possible genotypes (combination of alleles) & 2 possible phenotypes (the dominant one or the recessive one).
