If the father had the gene BB (purebred & not carrying colourblind allele), then the answer will be a). All of their children will have normal vision with half of them carrying the colourblind allele.
If the father had the gene Bb (hydrid & carrying colourblind allele), then the answer will be d). 3/4 of their children would have normal vision whilst the last quarter would have colourblind males. This is due to them having to receive one colourblind allele from their mother on the X chromosome & one colourblind allele from their father on the Y chromosome.

Can you create a punnett square for this question?
Ierofanga [76]

Answer:

The correct answer is 50%.

Explanation:

In the given question, the table says that fruit color is determined by the incomplete dominance of allele R and R'. In the case of RR genotype the fruit color will be red and R'R' the food color will be yellow but in the heterozygous condition the color would be orange, so the cross between RR' and R'R' would be as follow:

Punnett square:

      R       R'

R'    RR'   R'R'

R'    RR'   R'R'

It is found by the given cross that the cross between RR' and R'R' would form two orange fruit plants out of four which is 50%

List and describe the purpose of each component of the restriction enzyme digest. Why do some tubes have no restriction enzyme?.
Arisa [49]

A typical restriction digestion reaction includes the DNA template, the desired restriction enzyme, a buffer, and occasionally BSA protein.

<h3>How come a restriction enzyme wouldn't function?</h3>

You should always check the expiration date, confirm that the enzyme has been stored at -20°C, and check the temperature of your freezer (do not allow temperatures to surpass -20°C, since many freeze-thaw cycles may cause an enzyme to lose action).

<h3>How does a restriction digest work?</h3>

With the aid of specialized enzymes known as restriction endonucleases (often referred to as restriction enzymes or REs), restriction digestion is the process of breaking down DNA molecules into smaller fragments.
