Describe at what level gene expression is generally controlled?
gene expression is generally controlled during transcription
The hardy-weinberg states that in a population do not change unless outside factors affect the gene pool?
allele frequencies
The Hardy-Weinberg principle states that in a population do not change unless outside factors affect the gene pool.?
allele frequencies
The Hardy-Weinberg principle states that in a population do not change unless outside factors affect the gene pool?
allele frequencies
Explain how different factors can affect a population's gene pool?
Factors such as mutations, gene flow (migration), genetic drift, natural selection, and non-random mating can all affect a population's gene pool. Mutations introduce new genetic variation, gene flow can introduce new alleles, genetic drift can cause random changes in allele frequencies, natural selection can favor certain alleles, and non-random mating can lead to preferential inheritance of specific genotypes, ultimately influencing the genetic diversity of the population.
Is excessive sweating caused by genes or environmental factors?
excessive sweating is basically controlled by a multifactorial gene (polygenic with environmental influence ) . ( shiza mumtaz )
Is a non mendelian trait controlled by one gene?
A non Mendelian trait can be controlled by one gene. When a trait is controlled by one gene it results in genetic disorders. Examples of disorders due to single gene inheritance - Huntington disease, Fragile-X syndrome.
The traits of an organism are controlled?
Gene
What are the two base color genes for horse?
The base color is black/red factors, controlled by the Extension gene. A horse with one or two copies of the Extension gene (Ee or EE) will have black factors. A horse with no copies of the Extension gene (ee) will be chestnut.The Agouti gene acts on the Extension gene by limiting where the black factors are displayed, into points such as the legs, mane, tail, muzzle, and ears. A horse with at least one copy of the Extension gene that doesn't not have a copy of the Agouti gene will be black, provided that no other gene modify the color. One or two copies of the Agouti gene in combination with the Extension gene will result in a bay horse. A chestnut horse (no copies of the Extension gene) can have copies of the Agouti gene, but it will not affect the horse's color, as the horse has no black factors for the Agouti gene to limit.
Which process adds genes to a gene pool?
Over generations, small changes in the amount of each type of gene can happen because of several processes. Those processes are Gene mutation, Gene flow, Genetic drift, and Natural selection.
A gene that interrupts the normal functioning of life processes and results in death is a?
a lethal gene
WHAT is single gene trait?
A single-gene trait is a phenotypic trait controlled by two homologous alleles.
