Which of the three types of viruses shown above would you expect to include glycoproteins?

Mademuasel [1]

The correct answer is D: I and II only.
Viruses have protein capsids, which protect their genetic material. This capsid sometimes is covered by viral envelopes which have glycoproteins on their surface. Glycoproteins help in the process of binding to the host cell and infecting it. In this example, virus III has the structure of a bacteriophage and it does not seem to have glycoproteins. Bacteriophages use their tail fibers to attach to the bacterial host and inject their genetic material. On the contrary, viruses I and II have glycoproteins sticking out of their envelopes.

Free earlobes are dominant over attached earlobes. What is the probability that a woman with attached earlobes (homozygous reces

AVprozaik [17]

<h2>The correct answer is explained below:</h2>

Explanation:

According to the question, free ear lobes are dominant over attached ear lobes.
Let the allele for free ear lobes be represented by F.
Let the allele for attached ear lobes be represented by f.
The genotype of the homozygous recessive woman (mother) having attached ear lobes is : ff.
The gamete produced by the woman is: f.
The genotype of the heterozygous man (father) with free earlobes is: Ff.
The gametes produced by the man are: F and f.
Mating the man with the woman we get the following offspring,

F f

f Ff ff

Phenotype Free ear lobe Attached ear lobe

The genotype and the phenotype of the probable children obtained is represented in the Punnett square above.
The probability that the parents would produce children with attached ear lobes is = $\frac{1}{2}$ .
