How does gene flow contribute to evolution?
When you have one population entering into another population the gene pools of the two populations are different. Thus, new combinations of alleles get together and new phenotypes can arise. This changes allele frequency just by the flow, so that is the definition of evolution. ...

What is the difference between recombinant and parental chromatids and how do they arise?
Parental chromatids are chromatids that have a combination of alleles identical to the parents and Recombinant chromatids are chromatids that have a mix of alleles from both parents. ...

How many alleles per gene do you have in a diploid cell?
The number of different variants, or alleles, of a given gene, varies from gene to gene, from species to species. Not only every single gene can have different variants present in nature ( or wild type genes ), but new mutations can arise. ...
Where do new species come from?
Generally when a species splits into two populations that are separated by some means that keeps the now individual gen pools from intermingling. This allows new alleles to arise in the separate populations and as time passes this frequency changes in alleles can give rise to new species. ...

What was the idea that cells arise from the division of preexisting cells stated by?
The idea that cells arise from pre-existing cells forms part of cell theory, which was developed during the 17th century. ...

How many 4 number combinations can made from four numbers?
Like 1235 or 8067? If you allow leading zeros, then 10 000. If you disallow leading zeros, then 9 000. * * * * * Those are the numbers of PERMUTATIONS, not COMBINATIONS. In combinations the order does not matter, so 1234 = 4312 = 2314 etc. The number of combinations is (10*9*8*7)/(4*3*2*1) = 210. The question of leading 0s does not arise because there is no order to the set of numbers in the combination so there is no "leading". ...
Asked in Digestive System
What are the tiny spherical complexes of emulsified fat that arise during digestion?
Micelles (My-cells) : tiny spherical complexes of emulsified fat that arise during digestion; most contain bile salts and the products of lipid digestion, including fatty acids, monoglycerides, and cholesterol. ...
Why did paramilitary organization arise in the south during reconstruction?
Defeated troops who were unemployed - as in Germany in the 1920's.
Where do you expect genetic differences between cells to arise from mitosis or from meiosis?
Genetic differences arise during meiosis due to crossing over , independent assortment/random segregation and genetic mutations, which result in variation. ...
