Budding , mitosis and regeneration have no link with genetic variation.All variations in human being and other organisms are produced by MEIOSIS. During meiosis following important processes take place which include 1; crossing over in Prophase I ; Independent assortment of chromosomes and genes during Metaphase I , both of them result in reshufling of genes which is base of variation. Another source of variation is MUTATION.

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.
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.
Molecules responsible for hereditary and variation of organisms?
DNA is responsible in most organisms, but RNA is responsible for heredity and variation of a lot of viruses.
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 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.
What can genotypic variation in a population increase through?
Not to sure
A bell shaped curve of phenotypic variation is a representation of?
continuous variation.

What is variation what is a natural selection?
variation is the differences in genotypic traits between individuals in a populationnatural selection is any naturally occurring process resulting in differential success of reproduction of individuals depending on the genotypic traits they have expressed as phenotypic traits, the usual means by which this happens is the death of specific individuals prior to being able to reproduce but other events can alter the rate of success of reproduction without the individuals dying (e.g. they reproduce OK themselves but fail to bring those offspring to reproductive age successfully).
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 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 are the two types of variation?
The two types of variation are continuous variation and discontinuous variation. Continuous variation refers to characteristics that can vary along a spectrum, such as height or weight. Discontinuous variation refers to traits that have distinct categories, like blood type or eye color.
Molecules responsible for hereditary and variation of organisms?
DNA is responsible in most organisms, but RNA is responsible for heredity and variation of a lot of viruses.
Which is responsible for genetic variation mitosis or meiosis?
Meiosis is responsible for genetic variation
