How does genetic variation arise in a population?

Biology
1 answer:
MrRissso [65]3 years ago

Genetic variation can be caused by mutation (which can create entirely new alleles in a population), random mating, random fertilization, and recombination between homologous chromosomes during meiosis (which reshuffles alleles within an organism's offspring).

Which region of Earth’s crust experiences the least amount of pressure? crust mantle outer core inner core
Ne4ueva [31]

The correct answer is the crust.  

The crust is present above the mantle and is the hard outer shell of the Earth. The crust is 0 to 32 km in thickness. The densest type of crust is oceanic crust with the density of 3.0 g/cm3. The mantle is the layer below the crust and above the core.  

The mantle exhibits an average density of 4.5 g/cm3. The density increases with depth as the pressure increases. The outer core exhibits a density between the range of 10 g/cm3 to 12.3 g per cm3 and the density of the inner core is about 12 g/cm3. Showing that the inner core exhibits the highest pressure.

What is the difference between genotype and phenotype
dlinn [17]

Answer:

  • person’s <u>genotype</u> is their unique sequence of DNA. More specifically, this term is used to refer to the two alleles a person has inherited for a particular gene. <u>Phenotype</u> is the detectable expression of this genotype – a patient’s clinical presentation.

Explanation:

person’s phenotype results from the interaction between their genotype and their environment.

The connection between genotype and phenotype is not always clear-cut. This means that you may encounter disparities between your patient’s genomic test result and their clinical presentation. Similarly, the phenotype of patients with a given genetic condition may vary greatly even within families.
