They are energy production, energy storage, building macromolecules, sparing protein, and assisting in lipid metabolism
hope this helps :)
C.only determines phenotype when a dominant allele for the same trait is present.
Answer:
During meiosis Prophase I, crossing over occurs which increases genetic diversity.
Explanation:
The Punnett square is a valuable tool, but it's not ideal for every genetics problem. For instance, suppose you were asked to calculate the frequency of the recessive class not for an Aa x Aa cross, not for an AaBb x AaBb cross, but for an AaBbCcDdEe x AaBbCcDdEe cross. If you wanted to solve that question using a Punnett square, you could do it – but you'd need to complete a Punnett square with 1024 boxes. Probably not what you want to draw during an exam, or any other time, if you can help it!
The five-gene problem above becomes less intimidating once you realize that a Punnett square is just a visual way of representing probability calculations. Although it’s a great tool when you’re working with one or two genes, it can become slow and cumbersome as the number goes up. At some point, it becomes quicker (and less error-prone) to simply do the probability calculations by themselves, without the visual representation of a clunky Punnett square. In all cases, the calculations and the square provide the same information, but by having both tools in your belt, you can be prepared to handle a wider range of problems in a more efficient way.
In this article, we’ll review some probability basics, including how to calculate the probability of two independent events both occurring (event X and event Y) or the probability of either of two mutually exclusive events occurring (event X or event Y). We’ll then see how these calculations can be applied to genetics problems, and, in particular, how they can help you solve problems involving relatively large numbers of genes.
A virus is a tiny organism and may lead to mild-severe illnesses in animals or plants or humans.
Biologically we can term virus as a bit of RNA or DNA in a protein coat. It cannot replicate without another organism.
If we use an image of indicator, we may say yes virus is living. This is because the virus particle is non-cellular but has an NDA core.This core is enclosed in a protein coat and it has spike-like projections in all over its surface.
