Epistasis is observed when the allele of one gene masks the effects of another gene. Use the Punnett square to answer the question. AB Ab aB ab AB AABB black AABb black AaBB black AaBb black Ab AABb black AAbb brown AaBb black Aabb brown aB AaBB black AaBb black aaBB yellow aaBb yellow ab AaBb black Aabb brown aaBb yellow aabb ? What color would a dog's fur be if its genes are aabb? (1 point) Responses brown brown white white black black yellow
Based on the given genotypes, if a dog's genotype is aabb, the corresponding fur color is white.
In this specific case, since the alleles associated with aa and bb indicate no dominant alleles for black, brown, or yellow fur are present, the resulting color would be white.
Which best describes a provirus?(1 point) Responses A provirus is viral DNA incorporated into the host cell’s DNA. A provirus is viral DNA incorporated into the host cell’s DNA. A provirus is newly replicated viral DNA after injection. A provirus is newly replicated viral DNA after injection. A provirus is the host cell’s DNA that has been destroyed. A provirus is the host cell’s DNA that has been destroyed. A provirus is bacterial DNA incorporated into viral DNA.
The best description of a provirus is: A provirus is viral DNA incorporated into the host cell’s DNA.
Why is it difficult to produce a vaccine for the common cold in humans?(1 point) Responses It is caused by retroviruses that insert viral RNA into the host cell's DNA. It is caused by retroviruses that insert viral RNA into the host cell's DNA. It attacks white blood cells that fight off foreign bodies. It attacks white blood cells that fight off foreign bodies. It is a spherical-shaped virus with many protein receptors. It is a spherical-shaped virus with many protein receptors. It has a viral genome that mutates very quickly.
The correct response is: It has a viral genome that mutates very quickly.
This rapid mutation makes it challenging to create effective and long-lasting vaccines for the common cold, as the virus can change its structure frequently.
How is the HIV virus different from most viruses such as the common cold or influenza?(1 point) Responses It attacks neurons in the nervous system and causes paralysis. It attacks neurons in the nervous system and causes paralysis. It has viral DNA that is transmitted through indirect contact with infected persons It has viral DNA that is transmitted through indirect contact with infected persons It copies the information for reproduction from RNA into DNA. It copies the information for reproduction from RNA into DNA. It attacks and destroys red blood cells in the bodies of its host organisms.
The correct response is: It copies the information for reproduction from RNA into DNA.
HIV is a retrovirus, meaning it uses reverse transcription to convert its RNA genome into DNA after infecting a host cell, which is a key difference from many other viruses that do not follow this process.
