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?

Answer 1

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%**.
