Answer:

c) Negri bodies are a diagnostic sign of Rabies virus infection.

Explanation:

Rabies is an infection caused by rabies virus which affects the neurons and causes inflammation of the brain. It is a deadly disease and many animals are carriers of this disease like dogs, cats, raccoons, wolf, bats, fox, etc.

It is diagnosed by the presence of Negri bodies in the cytoplasm of nerve cells. Negri bodies are inclusions that are round or oval shapes having a size between 0.25 to 27 μm. Negri bodies can be frequently diagnosed in Purkinje cells of the cerebellum and pyramidal cells of Ammon’s horn.

Apart from these cells, they can be found in various ganglia, neurons of the tongue and other organs. So the correct answer is c.

What is the advantage for the medical community to use a "universal" language?

rosijanka [135]

Using a universal language makes it easy for medical professionals all around the world to communicate their ideas and findings, as well as comment on and test the experiments of each other. If there was no universal language among professionals internationally, then we would have a much more difficult time exchanging information as having to translate and convert each country's respective medical language into one's own would greatly damage the efficiency of medical communication and would possibly heavily slow the advancement of the medical field.

Which of the following genotype(s) would be considered 'purebred'

mixer [17]

D. both a and b
homozygous means that the genotypes would be the same. so, homo dominant (ex. RR) and homo recessive (ex. rr) would be considered purebred genotypes

Red-green color blindness is an x-linked recessive condition in humans. a man with normal vision had 8 children with a women tha

Ray Of Light [21]

<span>1) recessive allele is b
dominant allele is B
When an X chromosome contains the dominant allele,is written as: $X^B$
</span><span>When an X chromosome contains the recessive allele, is written as: $X^b$ </span>

2) the genotype of the woman is $X^BX^b$ She is not color-blind but she is a carrier of red-green color blindness, who passed the allele to their sons.
Woman, have two X chromosomes. If she is not colorblind is because there is the dominant allele making her see normally. But, she is a carrier, so while one X chromosomes has the dominant allele, the other has the recessive (making her carry the disease).

An AAbb strain is crossed to an aaBB strain and the resulting progeny self-crossed. If A andB are located 10 cM apart from each

skelet666 [1.2K]

Answer:

20.3%

Explanation:

Given that:

An AAbb strain is crossed to an aaBB strain

i.e.

AAbb × aaBB

gametes Ab aB

For F₁

generation;

If the resulting progeny are now self-crossed.

We know that the genetic distance between these two genes on the same chromosome is said to be 10 cM.

i.e. the recombinant gene = 10%; Hence, the parental gene will be (100 - 10)% = 90%

Ab × aB = Aa AB ab Bb

From above; the parental gene;

Ab and aB = 90% with each being 45%

i.e. Ab = 45% and aB = 45%

while the recombinants genes are:

AB and ab = 10%

i.e. AB = 5% and ab = 5%

Finally; the percentage of aaBB is = aB% × aB% × 100%

the percentage of aaBB is = 0.45 × 0.45 × 100%

the percentage of aaBB is = 20.25% ≅ 20.3%
