It refers to making or crating new genes in form of mutation
in duplicates of old genes. It is also a mechanism in major way through new
genetic material is generated during evolution. The duplication happens in
event termed unequal crossing over or recombination between misaligned
homologous chromosomes during meiosis.
Answer:
Answer C
Explanation:
has the same genetic information and ecological niche.
Answer:
Half would have the genotype Aa.
Explanation:
Given that the genotype of both of the parents was "Aa"; both parents would make two types of gametes. The 50% gametes from each parent would carry allele "A" while the rest 50% gametes from each parent would carry allele "a".
The random fusion of gametes of two parents would give the progeny with genotype ratio 1/4 AA: 1/2 Aa: 1/4 aa.
Answer:
The water treatment plant does not work properly.
Explanation:
The data from the river samples showed that there was a problem with the water treatment plant because there is high amount of pollutants are present in the river sample. The presence of pollutants in the samples shows that the water treatment plant did not work properly, if they did no pollutants are present in the river water so this presence of pollutants indicates inefficiency of water treatment plant.
Mitosis is the process of cell division that creates a new cell identical to the original. Somatic cells, such as muscles, hair and skin, undergo mitosis regularly in humans and other organisms. This is an important type of cell division needed to facilitate the repair of damaged cells, growth and replacement of old cells with new ones.
When a new cell is created, it must have the same library of genetic information all other cells in the body have access to. Because all the material in the new cell must come from the first cell, the original cell must make a copy of its DNA before completing the process of mitosis. These two sets of DNA only exist for as long as it takes the cell to undergo mitosis, which can be anywhere from 30 to 90 minutes in certain human cells. When the cell division is complete, both of the cells have a single identical copy of DNA.
