So there are four types of mountains and these are fault block mountains, fold and thrust mountains, unwarped or dome mountains and volcanic mountains.
Based on the given locations above, the Sierra Nevada mountains of California are fault block mountains. The Alps of Europe is an example of a fold and thrust mountain. The Black Hills of South Dakota and Teton range of Wyoming are unwarped or dome mountains. Hope this answer helps.
Answer:
4: epistasis
Explanation:
<em>Epistasis is a form of gene interaction in which a gene on one locus modifies or suppresses the effects of another gene on a separate locus. </em>
Epistatic gene interaction can be dominant, recessive, duplicate recessive, duplicate dominant, or polymeric gene interaction.
- Recessive epistasis occur when a recessive allele at one locus suppresses the expression of alleles on separate locus/loci.
- Dominant epistasis occur when a dominant allele at one locus suppresses the expression of alleles on separate locus/loci.
- Duplicate recessive epistasis occur when recessive alleles at either of two loci suppress the expression of dominant alleles at the two loci.
- Duplicate dominant epistasis occur when dominant alleles t either of two loci suppress the expression of dominant alleles at the two loci.
- Polymeric gene interaction occur when two dominant alleles which have similar effect individually produce enhanced effect when they come together.
<em>In this case, the expression of gene is controlled by the presence/absence of gene N on a separate locus. In homozygous recessive form, gene N suppresses the expression of gene S, a clear case of recessive epistasis.</em>
The correct option is option 4.
The genetic variations seen in and between populations are known as human genetic variation.
Humans differ genetically from one another. Due to developmental mutations and gene copy-number variation, even monozygotic twins, who arise from a single zygote, may differ genetically. Techniques like genetic fingerprinting rely on individual differences, even between closely related people.
There are 324 million identified variations from sequenced human genomes as of 2017.
A person's genome typically differs from the reference genome by 20 million base pairs, or 0.6% of the total 3.2 billion base pairs, as of 2015.
In contrast to other species, humans are genetically uniform. While a limited number of genetic variations are found more commonly in particular geographic regions or in individuals with ancestry from those places, this variance accounts for the majority of genetic variation.
Genetic variation between populations occurs for at least three reasons. If an allele offers a competitive advantage, natural selection may endow people with an adaptive advantage in a particular environment.
