Cross a parent that is homozygous recessive for both traits (bbee) with a dihybrid (BbEe). First, draw a Punnett square in your

Bas_tet [7]

In this question, one parent is homozygous recessive (bbee) and other parent is dihybrid (BbEe)
B - black fur dominant trait
b - white fur recessive
E- black eyes dominant
e - red eyes recessive

a punnett square shows all the possible combinations of genotypes with the corresponding phenotypes that the offspring could inherit.
the genotypes and their phenotypes for the offspring are given below ;
BBEE / BbEe / BbEE / BBEe - black fur and black eyes
Bbee / BBee - black fur and red eyes
bbee - white fur and red eyes
bbEe / bbEE - white fur and black eyes

after analysing the punnett square the following results are obtained;
black fur and black eyes - BbEe- 4/16
black fur and red eyes -Bbee - 4/16
white fur and black eyes - bbEe - 4/16
white fur and red eyes -bbee - 4/16

Activated

Explanation:

In the presence of lactose, and in the absence of glucose, lactose will bind to a protein called a "repressor," deactivating it. Through this, RNA polymerase has a free way to synthesize the mRNA that will give enzymes for lactose degradation.

What would the genotype of the parent mice need to produce offspring with the genotypes. FF and Ff? (An empty punnet square is p

zhenek [66]

The genotypes of the parents to produce offspring with the genotypes FF and Ff are FF and Ff.

<h3>What is Punnett square?</h3>

The Punnett square is a graphical representation used to determine the frequency of a given genotype.

In this case, the Punnett square may be (alternatively, parents can also be heterozygous):

F f

F FF Ff

In conclusion, the genotypes of the parents are FF and Ff.
