What is Genotype?</h3>
An organism's genotype is made up of all of its genetic components. The alleles or variations that a person holds in a specific gene or genetic region are also referred to as the genotype.
The amount of copies of each chromosomes found in that species, also known as ploidy, determines how many alleles a person can have for a certain gene. In diploid organisms like humans, there are two complete sets of chromosomes, which means that each person has two different alleles for each gene. Homozygous refers to a genotype where both alleles are the same. Heterozygous refers to a genotype when there are two distinct alleles.
Phenotype, the observable qualities and attributes of an individual or creature, is influenced by genotype.

It occurs only in cells in the reproductive structures of organisms.
Meiosis only occurs in the reproductive cells, producing gametes with half of the genetic information as the parent cell.
Answer:
Renewable energy resource as an obstacles for the growth of migratory salmon populations: It is now believed that the reduce access to spawning grounds and nursery areas, leading to a decrease in migratory fish populations is due to the dam structures of large storage-type schemes, which can create great obstacles for the movement of migratory fish species.
Explanation:
- Storage-type schemes ( big dams) can significantly change the downstream flow regime,and may also alter water temperature and quality, and even make it inhabitable for fish to live.
- As the storage of water can be linked with high evaporative losses, which in turn results in high life cycle water footprints compared to other sources of electricity.
<u>Run-of-river (ROR) schemes are HEP schemes: </u>
They operate without water storage, using the flow within a river channel.They are ecologically friendly and do not disturb the natural mechanism for the migrating salmons.
Working Principle:
They are normally used to regulate water levels, which allows a proportion or part of flow to be diverted down a secondary channel to a turbine before it is returned to the main channel further downstream.
There are some modern turbine types used in ROR HEP(hydroelectric power) schemes, which are also designed to allow fish to pass through the system unharmed if the fish do pass through the intake screens.
