Patterns of Inheritance

The following picture represents what pattern of inheritance?

• Complete dominance
• Incomplete dominance
• Co-dominance
• Sex-linked inheritance

The following picture represents what pattern of inheritance?

• Complete dominance
• Incomplete dominance
• Co-dominance
• Multiple Alleles

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

In the blood type Punnett square shown, what is the probability the offspring will inherit each blood type?

• 50% A, 25% B, 0% AB, 25% O

• 25% A, 50% B, 25% AB, 0% O

• 50% A and 50% B

• 25% AB, 50% A, 25% O

In completely dominant traits, is it possible for two recessive parents to have a dominant phenotype offspring?

• Yes

• No

If an allele for blue flower color (B) and an allele for yellow flower color (Y) are incompletely dominant, what color will a BY flower be?

• Blue

• Yellow

• Blue and Yellow

• Green

If the allele for black feather color (B) and white feather color (W) in chickens are codominant, then a BW chicken will have:

• black feathers

• white feathers

• black and white feathers

• gray feathers

In complete dominant inheritance, is it possible for two dominant parents to have a recessive phenotype offspring?

• Yes if they are both heterozygous

• No

• Not sure

• Yes if they are both homozygous dominant

How are Incomplete Dominance and Co Dominance different than a normal Mendelian cross?

• There is no difference
• The heterozygous genotype has a unique phenotype
• There is no heterozygous genotype
• There is only one phenotype regardless of genotype.

Do a Punnett Square.

A heterozygous type A parent reproduces with a heterozygous type B parent. Which correctly describes the probability of blood type in their offspring?

• 25% Type A, 25% Type B

  25% Type AB, 25% Type O

• 50% Type A

  50% Type B

• 25% Type A, 25% Type B

  50% Type AB

• 50% Type AB

  50% Type O
