. BB - black color
2. Bb - black color
3. Bb - black color
4. bb - white color
make this into a punnent square
To create a Punnett square for this scenario, we need to cross the alleles of the parental generation.
Let's represent black color as "B" and white color as "b".
| B | b
-------------|-------------|-------------
B | BB | Bb
b | Bb | bb
In the Punnett square, the top row represents the alleles from one parent (1st column) and the alleles from the other parent (2nd column). The left column represents the possible alleles from one parent (1st row) and the alleles from the other parent (2nd row).
Based on the provided information, the Punnett square shows the four possible combinations of alleles and their corresponding colors in the offspring.
To create a Punnett square, we need to determine the possible combinations of alleles from the two parents. In this case, we have two alleles for color: "B" representing black and "b" representing white.
Let's label the alleles from one parent as follows:
Parent 1: BB
And the alleles from the other parent:
Parent 2: Bb
To create a Punnett square, we need to list all possible combinations by crossing the alleles:
B B
-----------------
B | BB | BB |
-----------------
b | Bb | Bb |
-----------------
Looking at the Punnett square, we can see that the possible offspring genotypes are:
- BB: black color
- Bb: black color
- Bb: black color
- bb: white color
So the genotypic ratio is 3 black (BB or Bb) to 1 white (bb) offspring.
