 Dominance Patterns and Autosomal/Sex-Linkage.

Dominance of Mutant Allele Autosomal Sex-Linked XX-XY(O) Sex-Linked ZZ-ZW
Recessive Phenotype
  1. The F1 and F1 reciprocal crosses give the same results.
  2. The F1 progeny (male and female) are all phenotypically wildtype.
  1. The results of the reciprocal crosses are different.
  2. F1 males have the phenotype of their mothers.
  3. F1 females are phenotypically wildtype
  1. The results of the reciprocal crosses are different.
  2.  F1 females have the phenotype of their fathers.
  3. F1 males are phenotypically wildtype

 

 Dominant Phenotype

Incompletely Dominant Phenotype
  1. The F1 and F1 reciprocal crosses give the same results.
  2. The F1 progeny (male and female) have a phenotype that is intermediate to the parental phenotypes.
  1. The results of the reciprocal crosses are different.
  2. F1 males have the phenotype of their mothers.
  3. F1 females have a phenotype that is intermediate to the parental phenotypes.

Overdominant Phenotype
  1. The F1 and F1 reciprocal crosses give the same results.
  2. The F1 progeny (male and female) show a phenotype that is more extreme than either of the parental phenotypes.

  3. F1 females have the phenotype of their fathers.
 
Codominant Phenotype
