Is the Law of Dominance a non-Mendelian trait?
No
The Law of Dominance states that when a _ dominant trait is crossed with a _ trait, the result would be the expression of the _ trait in all resulting offspring.
The Law of Dominance states that when a homozygous dominant trait is crossed with a recessive trait, the result would be the expression of the dominant trait in all resulting offspring.
Phenotype is the _ _.
Genotype is the _.
Phenotype is the Physical Manifestation.
Genotype is the Gene.
Enumerate the non-Mendelian traits.
Incomplete Dominance
Codominance
Sex-linked Inheritance
Multiple Alleles
(non-Mendelian) The offspring does not completely express the dominant trait.
