A) In the Dunker population, the frequency of IB allele is 0.3 and the frequency of i allele is 0.4. In the general population, the frequency of IB allele is 0.1 and t<span>he frequency of i allele is 0.5.
</span>
If:
$I^{A}$ - <span>the frequency of IA allele
</span> $I^{B}$ - <span>the frequency of IB allele
</span> $i$ - t<span>he frequency of i allele

Then:
</span> $I^{A} I^{A}$ + <span> $I^{A} i$ - the frequency of individuals with A blood type
</span> $I^{B} I^{B}$ + <span> $I^{B} i$ - the frequency of individuals with B blood type
</span> $ii$ <span>- the frequency of individuals with O blood type
</span>
Let's first take a look on the Dunker population:
$I^{A} = 0.3$
$ii=0.16
$

<span>Since there is only one possible genotype for O individuals - ii - the frequency of the allele i is square root of the frequency of O individuals:
</span> $i= \sqrt{ii}$
⇒ $i = \sqrt{0.16}$
⇒ $i=0.4$

Now, we have the frequencies of two alleles ( $I^{A}$ and $i$ ). To calculate the frequency of $I^{B}$ <span> allele, we will use the formula:
</span> $I^{A} + I^{B} + i = 1$
⇒ $I^{B} = 1- I^{A} - i$
⇒ $I^{B} = 1-0.3-0.4$
⇒ $I^{B} = 0.3$

Now, in the general population:
$I^{A} = 0.4$
$ii=0.25$

<span>Similarly to the work for the Dunker population:
</span> $i= \sqrt{ii}$
⇒ $i = \sqrt{0.25}$
⇒ $i=0.5$

$I^{A} + I^{B} + i = 1$
⇒ $I^{B} = 1- I^{A} - i$
⇒ $I^{B} = 1-0.4-0.5$
<span>⇒ $I^{B} = 0.1$
</span>

b) A founder effect is a result of geographical separation of a few individuals from the original population. Those founding individuals will form a new population. The Dunker population was not only geographically separated, but also genetically. The group interbreeding was present resulting in increasing those allele frequencies that were the most common in the founding population. In this case, the most individuals from the founding population had B blood type.

An E. coli F(+) cell

Phantasy [73]

Answer:

The correct answer will be option- C.

Explanation:

The bacteria can transfer its genetic material through three processes: transformation, conjugation and transduction. The process of conjugation takes place through the formation of the conjugating tube formed of the pili, the membrane extensions of the bacteria.

These pili are known as fertility pili or F-pili as they transfer the F-plasmid or fertility plasmid from the F⁺ bacteria containing the F-plasmid to the F⁻ cells or the bacterial cells which lack the F-plasmid.

Thus, option- C is the correct answer.

Give the names of two co- enzymes that take part in the cellular respiration.

olya-2409 [2.1K]

Answer:

Explanation:

Two of the most important and widespread vitamin-derived coenzymes are nicotinamide adenine dinucleotide (NAD) and coenzyme A. ... When NAD loses an electron, the low energy coenzyme called NAD+ is formed. When NAD gains an electron, a high-energy coenzyme called NADH is formed.
