Phenotype variation is slight variations in a phenotype that are caused by the expression of an organism's genes or the influence of environmental factors. A species can have several different phenotypes within it.

∙ 9y agoPhenotype variation is differences within a species that are not enough to consider it a different species altogether. One example of this is differences in coloration in birds of the same species or human blood types.

What kind phenotypic changes are the of the result of evolution?
Changes that are genetic
What are the different kinds of variation?
Continuous Variation and Discontinuous Variation.
Is a scar a discontinuous variation?
It is a continuous variation which is not by birth. It is an injury which will slowly change so a scar is a continuous variation.
What terms refers to a situation where a single phenotypic character is determined by the additive effects of two or more genes?
Polygenic.
Which habitat would have the least variation in its salinity?
Lakes usually have the least variation in salinity.
A bell shaped curve of phenotypic variation is a representation of?
continuous variation.
Which cross would produce the least phenotypic variation?
There are two choices that produce the least phenotypic variation. AA times aa produces only Aa offspring. AA times Aa produces and AA and Aa offspring.
What are some of the phenotypic variations that are possible with codominance?
Blending or mixing of the colors is a phenotypic variation that is possible with co-dominance. Seeing both colors present at the same time is also possible.
What causes varation in traits?
Genotypic variation is caused by mutation. Phenotypic variation can be caused by mutation, which gives rise to different alleles, or it can be caused by environmental factors.
Difference between broad sense heritability and narrow sense heritability?
Broad sense heritability A.K.A (H) is the degree in which phenotypic variation is due to genetic factors Narrow sense heritability A.K.A (h) is the degree in which phenotypic variation is due to additive genetic factors. in maths terms... H = Vg/Vt h = Va/Vt Vg= genetic varaition Vt = total variation Va = additive variation
What was Mendel contribution in science?
Gregor Mendel was the father of heredity. His experiments with pea plants established principles of dominance and recessiveness in phenotypic variation.
What is a heritable feature?
Heritability is the proportion of Phenotypic variation in a population that is attributable to genetic variation among individuals. Phenotypic variation among individuals may be due to genetic and/or enviromental factors. Heritability analyses estimate the relative contributions of differences in genetic and non-genetic factors to the total phenotypic variance in a population.
What is a natural variation in a population?
Look at a population of humans. Your class will do. Now, how many different heights, hair colors and other assorted phenotypic variations can you see in this small population?This is the frequency of alleles of these types that we call natural variation.
How many types of variation are there?
There are hundereds of cheese types. These can all vary depending on the area/district/country you are in. Cheeses all have different varieties as it can depend on the producer.
What kinds of phenotypic are the results of evolution?
Changes that are genetic
What is the phenotypic ratio of the offspring when a tall man marries a short woman?
The phenotypic ratio of the offspring when a tall man marries a short woman is 3:1 (tall/short). The phenotypic ratio is figured by using the punnet square with the dominant allele for tall and the recessive allele for the short gene.
If both parents were Dd then what would the phenotypic ratio be?
Phenotypic ratio: 3 D, 1d [3 dominant, 1 recessive] Genotypic ratio: 1DD, 2Dd, 1dd
