Alex_Xolod [135]

Answer:

4 RW pink hair color

Explanation:

Let the allele for red hair color = R

Let the allele for white hair color = W

Let the allele for blue hair color = b

Since R and W exhibit co dominance it means none of both traits have the tendency or capability to masked the other .

As such individual with RW genotype = PInk hair color

Allele b is recessive and only individuals with the genotype bb exhibit the blue allele  

Now; if a cross occurs between a red-haired Mendelian and a white-haired Mendelian

i.e

RR   × WW

we have

           R           R

W         RW       RW

W        RW         RW

So we have the following offspring :

4 RW = 4 pink

So theoretically , the possible phenotypes results to 4 RW pink hair color

transported to the growing parts of the plant for use in respiration

transformed into cellulose, proteins and oils

turned into starch for storage

Therefore, to test if a plant has been photosynthesising, you can test the leaf to see if starch is present.
