What is the process in which DNA changes to form new alleles?
Crossing-over
What mutation causes a reshuffling of genes in existence?
Reshuffling of genesis caused by crossing over and not by mutation .
Is the only possible source of new genetic material?
mutations recombination/crossing over in mammals
What do sexual reproduction mutation and crossing-over generate in a population?
genetic diversity!:) ur welcome
What are two sources of genetic variation?
Natural and Artificial Selection
Differences in heritable trait arise trough?
crossing over during meosis and or due to mutation.
What are two main sources of genetic?
Crossing over of choromosomes and Mutation in cells. The law of independent assortment help as well.
What are some ways various ways that generic variation can be introduced in organisms that reproduce?
By crossing over, hybridization, mutation and artificial gene transfer.
What provides the source of variation in evolution?
Mutation, such as insertion, deletion and rarely frameshift mutation. Sexual recombination, is sexually reproducing species. This includes, in meiosis, the independent assortment of chromosomes and crossing over. Then there is random fertilization to provide a last source of variation.
Does crossing over help evolution create brand new beneficial genetic information useful for molecules to man evolution?
Not so much. Crossing over keeps genetic diversity within a population, but one needs a mutation to arise for real adaptive change to take place.
Will a point mutation cause the cell to make an incomplete polypeptide if the mutation results in a stop codon?
Yes, a point mutation will cause the cell to make an incompelete polypeptide chain that is non-functional, if the mutation results in a stop codon. This type of a mutation is also called as the Nonsense Mutation.
What ten causes of mutation are there?
you cause it cause you are weird
