Question

codominance

• codominance results in a phenotype that shows __ __ of an allele pair
• (red flower + white flower = red and white spotted flower)
• if morpeople have tail color alleles b(blue) and g(green) that follow the codominance inheritance rule, what are the possible genotypes and phenotypes?

genotypes	phenotypes

Explanation:

Step1: Define codominance rule

Codominance shows both traits fully (no blending). For alleles B (blue) and G (green):

• Homozygous BB = blue tail
• Homozygous GG = green tail
• Heterozygous BG = both blue + green (spotted/striped)

Step2: List all genotypes

Possible genotypes from B and G alleles: $BB$, $GG$, $BG$

Step3: Match to phenotypes

Map each genotype to its codominant phenotype:

• $BB$ → Blue tail
• $GG$ → Green tail
• $BG$ → Blue and green spotted/striped tail

Answer:

Genotypes	Phenotypes
$GG$	Green tail
$BG$	Blue and green spotted/striped tail

Additionally, the first blank about codominance: Codominance results in a phenotype that shows both traits of an allele pair.
