If a pink flowered snapchagon plant is crossed with a white flowered snapdragan plant. What will be the phenotype of their progeny?

Pink and white flowered

The correct answer is Option (4)- Pink and white flowered

When a pink-flowered snapdragon plant (which is likely heterozygous for flower color) is crossed with a white-flowered snapdragon plant (which is likely homozygous recessive for flower color), the possible outcomes for the progeny can be determined using Punnett squares.

Let's represent the alleles for flower color:

• Pink flower allele (dominant): R
• White flower allele (recessive): r

The pink-flowered plant's genotype could be Rr, and the white-flowered plant's genotype is rr.

The Punnett square for this cross would look like this:

From this Punnett square, we can see that:

• 50% of the progeny will inherit the Rr genotype, resulting in pink flowers.
• 50% of the progeny will inherit the rr genotype, resulting in white flowers.

Therefore, the progeny will have a mix of pink and white flowered snapdragon plants. So, option 4 is correct.
