Chapter 10 Complex Heredity

Incomplete dominance means that there traits are...

• expressed equally
• dominant
• recessive
• blended

Polygenic inheritance means that _________ control a characteristic

• many genes
• single genes
• 3 genes
• no genes

What do you call the non-Mendelian inheritance pattern where both traits are dominant and both appear in the organism with heterozygous genotype?

• Codominance
• Incomplete dominance
• Polygenic traits
• Multiple alleles

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

In the following Punnett Square, R represents red scales and B represents blue scales.  If scale type shows co-dominance in fish, what is the probability of each color in the offspring?

• 50% blue, 50% red and blue, 0% red
• 50% purple and 50% blue
• 100% red and blue
• 0% red, 0% blue, 100% red and blue
