Types of Inheritance

What pattern of inheritance is shown in this image?

• Codominance
• Incomplete dominance
• Polygenic traits

A breed of chicken shows codominance for feather color. One allele codes for black feathers, another codes for white feathers. The feathers of heterozygous chickens of this breed will be:

• all black
• all white
• all gray
• speckled black and white

incomplete dominance means that there traits are,,,

• expressed equally

• recessive

• Incomplete Dominance

• Codominance

• Independent assortment

• Recessive inheritance

The alleles of a gene pair in a heterozygote are both expressed with no blending.

• codominance

• incomplete dominance

• polygenic

• multiple alleles
