Question

You identify a gene that determines the size of the pods of a pea plant. To study the phenotype associated with this trait, you cross a plant that is homozygous for the “long pod” allele with a pea plant that is homozygote for “short pod” allele. When measuring the length of the pods of the parents and resulting offspring, you obtain the following data:

Plant
Length (cm)
Homozygous (“Wide” allele)
 15 cm
Homozygous (“Short” allele)
 4 cm
Resulting cross breed
 9 cm


What can you conclude about this phenotype/trait?

 

 

 
Long and short alleles are codominant
 
Wide allele shows incomplete dominance over the short allele
 
Wide allele shows complete dominance over the short allele
 
Short allele shows complete dominance over the long allele
 
The wide and short genes are linked
