Question

incomplete dominance
directions: use what you have learned about incomplete dominance to complete the punnett square. the color of snapdragon flowers show incomplete dominance.
when a red snapdragon (c^rc^r) is crossed with a white snapdragon (c^wc^w), the heterozygous phenotype is pink. show the cross between a pink snapdragon and a red snapdragon and then answer the questions about this cross.
*place the gametes for the pink snapdragon along the side and the gametes for the red snapdragon along the top the punnett square.

Explanation:

Step1: Determine genotypes

A pink snap - dragon has genotype $C^R C^W$ and a red snap - dragon has genotype $C^R C^R$.

Step2: Identify gametes

The pink snap - dragon ($C^R C^W$) can produce gametes $C^R$ and $C^W$. The red snap - dragon ($C^R C^R$) can only produce gametes $C^R$.

Step3: Fill Punnett square

	$C^R$	$C^R$
$C^W$	$C^R C^W$	$C^R C^W$

Answer:

The genotypes in the Punnett square are two $C^R C^R$ (red) and two $C^R C^W$ (pink). The phenotypic ratio is 1 red : 1 pink.
