Why did the lactose tolerance mutation in the east African herders spread so rapidly with in population?
It was a selective advantage for survival during droughts.
What is the definition for selective diffusion?
controls what enters and exits membrane by using proteins
How does genetic drift affect the population over time?
The effect a mutation has on a population depends on two factors: First, every new mutation has to overcome the effects of chance on its survival. New mutations,when they exist in only one or two individuals, are often lost from the population due to genetic drift, or chance. For example, the mutation may never make it into a gamete (egg or sperm) and be lost. Or the gamete carrying the mutation may not be involved in a fertilization. Or the individual carrying the mutation may not find a mate, or may be killed when young. It is estimated that 1 out of three new mutations, regardless of the selective advantage, may be lost this way. Secondly, the selective value of the mutation (given it has survived being lost early due to drift) can determine its affect on the population. If it is deleterious, selection will act to reduce its frequency or even eventually remove it. If the mutation is neutral, its frequency will drift up and down due to chance, eventually either being lost or fixed (reaching a frequency of 100%). If it has a selective advantage over other alleles, it may eventually become fixed as well--how long depends on the size of the population and the strength of the advantage.
How do you spell permeable selection?
The noun form is usually the reverse, "selective permeability." The adjective form is often used for a membrane, and would be selectively permeable or semipermeable.
Mutation is any change in a gene or chromosome?
mutations
What is a brief definition in mutation?
genetic disorder
What is the definition of selective transport?
selective transport is the transport of specific substances by means of protein channels and pumps.
Can anyone become a mutant by mutation?
The only way to become a mutant is via a mutation, but a mutation does not guarantee a unique phenotype. (I'm assuming, here, that you're using a biological definition of "mutant" and not a more fanciful definition.)
Definition of class 1 mutation?
Hannah Montana
What is the biology meaning of inversion?
A chromosomal mutation in which a block of genes in a segment is in reverse order
Why did the lactose tolerance mutation in the east African herders spread so rapidly with in population?
It was a selective advantage for survival during droughts.
What is the definition for selective diffusion?
controls what enters and exits membrane by using proteins
Is gene mutation within a species know as micro evolution?
Genetic mutation is one of the mechanisms for evolution.Micro-evolution by definition means very small changes in allele frequency (gene mutation).
The type of mutation in which a chromosome segment breaks away and recombines in reverse order is called?
inversion
In your own words write a definition for the word mutation?
mutation: a change in the sequence of DNA to cause a unusal trait
What required men to register with the government for random military service?
The Selective Service Act, although the definition you give of it is a bit misleading.
The definition of selective reproduction?
A process known to be an abortion of one or more of the embryos in pregnancy with cases of multi-fetal pregnancy. Also known as selective termination.
