Hi,

Let us get an introduction of the problem first, Incomplete dominance is a pattern of inheritance in which, offspring from the cross of two parents shows a phenotype that is not like either parent but in between both.

For example: Let us take the example of Oompah's hair that can be either red or purple or blue. As described in the question, Red is dominant so let us denote allele for Red hair with R. The other hair color is blue that is recessive, let us denote its allele with r. Now, there is another intermediate phenotype that is purple, let us denote it with Rr because it is derived through a combination of R and r.

Now, here is the key for all possible genotypes and phenotypes of Oompahs. There are only three possible genotypes and phenotypes for the hair color.

Genotype: Phenotype

RR             : Red hair

Rr              : purple hair

rr                : Blue hair

This is because no allele can fully express itself over the other. So is we cross a red hair Oompah with Blue hair Oompah, let us see what will happen:

                                                  RR x rr

Gametes:                              r        and        R

                                       rr:     Rr :     Rr     :  RR

It means that 25 % of the offspring will have red hair, 50% will have contain purple hair and 25 % will have blue hair.

RR:              Red hair      25%

Rr:               Purple hair   50 %

rr:                 Blue hair     25%

Hope it helps!

Answer: The combination produced is RRtt.

The combination rrTt does not appear in this punnett square.

Explanation:

As the problem does not indicate more information, I assume that punnett square is made between two RRtt genotypes. It can produce gametes that have the alleles Rt. A gamete is a sexual cell (egg or sperm) that has only one allele of each gene. And, each gamete codes for a different gene. Since here we have two different types of alleles (R and t), it is a dihybrid cross.

<u>A Punnett square is a diagram used to predict the genotypes of a cross or breeding experiment.</u> It is used to determine the genotypes and phenotypes of the offspring. To do it, you have to label the rows with one parent's gametes and label the columns with the other parent's genotype. Then, have each box inherit letters from its row and column, and interpret the results.

Then, the punnett square (shown in the picture) will be between RRtt and RRtt whose gametes can only be Rt, so Rt x Rt will be made.

The result in an offspring which will be 100% RRtt, and there is no rrTt combination here because non of the parents have an r allele, then none of the children can inherit it.

To have an offspring where rrTt genotype is shown, a different genotype must be used, in which both parents must have at least one r allele and one t allele. For example, it could be Rrtt x rrTt.

Answer:

Your answer is 2.

Explanation:

To calculate the mechanical advantage of a pulley you simply have to count the number of rope sections that support whatever object you are lifting (not counting the rope that is attached to the effort). For example, in a one pulley system the MA is 1. In a two pulley system the MA is 2.
