Answer:
Allele is the form in which sequenced information within a single gene can be expressed. One allele is paired with another within a gene, which is part of a chromosome and which determines the expression of specific traits.
Explanation:
The genetic information is contained in the DNA, and each molecule of this nucleic acid forms a chromosome containing genes, fragments of the DNA of the chromosome with a sequence of nucleotides for the synthesis of specific proteins.
Genes determine morphological or functional features of a living being. Each gene contains two alleles for each trait it determines, the alleles being different sequences of nucleotides that constitute different ways in which a trait can be expressed.
<h3>How are the alleles related to genes, chromosomes and traits?
</h3>
Each gene contains two alleles, either the same or different, with the sequence of nitrogenous bases to determine the possible ways in which a trait is expressed. The different sequences of the alleles can produce specific modifications of the function of that gene, conditioning the different forms of expression of a trait.
Genes, which contain alleles, are found within a chromosome, at a specific location called a locus.
Answer:
Incubation period
Explanation:
The incubation period is the time period between the entry of pathogen into the host body and the appearance of signs and symptoms. Chickenpox is caused by varicella-zoster virus that has an incubation period of 10-23 days after which the symptoms of the disease appear.
The virus must have spread from the infected nephew two weeks ago but did not cause any sickness until now due to the incubation period.
I'm a bit confused about this question. But I will try my best to answer. :)
To prevent a certain virus, or increase someone's immunity towards a virus, doctors give patients a shot/vaccine. For example, people get a flu shot yearly to help prevent them from getting the flu. The shot contains a small portion of the flu itself. The flu remains dormant until the body decides to activate it or fight it off. This also helps the body become more immune to the virus/sickness and fight it off easier.
I hope this helps! :)
