Question

.
In Camellia flowers, petal color is inherited codominantly with the possible colors being red, white, and red and white spots. What would be the chance of getting a red flower if you cross a spotted flower with a spotted flower?

In the case of Camellia flowers, if we denote the alleles for color as follows:

\( R \) = red (dominant)
\( W \) = white (also dominant)

For a flower to have spotted petals, it must have one red allele and one white allele, represented as \( RW \).

When crossing two spotted flowers (\( RW \) x \( RW \)), we can set up a Punnett square to find the possible offspring genotypes:

          R       W
       +---------------
     R |   RR    |   RW   |
       |--------------------|
     W |   RW    |   WW   |

From this Punnett square, the possible genotypes of the offspring are:

\( RR \) (red flower) - 1
\( RW \) (spotted flower) - 2
\( WW \) (white flower) - 1

This gives us the following ratios:

1 red (RR)
2 spotted (RW)
1 white (WW)

So, the chance of getting a red flower (RR) from this cross is \( \frac{1}{4} \), or 25%.

Therefore, the answer is 25%.
