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.
This is enough time to
allow the trunks of the clear-cut tree to be colonized by decomposers such as
fungi and bryophytes. At this time, the biodiversity richness could reach 80%
while biomass could reach 50%. Clear cut,
therefore, shows that natural regeneration is better than the active restoration of forests.
Answer: False
Explanation: It occurs in plants
animals recieve energy from the photosynthesis/energy when they eat plants
