Complex Inheritance Whiteboard Practice

In a species of birds, three feather colors are observed In a species of birds, three feather colors are observed. Birds can either be blue, yellow, or green. What type of inheritance pattern is this?

In a species of birds, three feather colors are observed. Birds can either be blue, yellow, or green. If two blue birds are crossed, what will be the possible genotypes and phenotypes of the offspring?

In a population of fruit bats, it is observed that bats with a wide wingspan always have red eyes. It is also observed that bats with a short wingspan always have black eyes. What can you conclude about the genes for wingspan and eye color?

Two parents think their baby was switched at the hospital Two parents think their baby was switched at the hospital. Its 1968, so DNA fingerprinting technology does not exist yet. The mother has blood type “O,” the father has blood type “AB,” and the baby has blood type “B.” What is mom’s genotype? What is dad’s genotype? What are the possible genotypes of the baby?

Draw a Punnett Square crossing the parents’ genotypes. Two parents think their baby was switched at the hospital. Its 1968, so DNA fingerprinting technology does not exist yet. The mother has blood type “O,” the father has blood type “AB,” and the baby has blood type “B.” Draw a Punnett Square crossing the parents’ genotypes. Does the evidence support the parents’ claim that the baby was switched at the hospital?

Two short-tailed (Manx) cats are bred together Two short-tailed (Manx) cats are bred together. They produce two kittens with long tails, seven short tails, and two without any tails. From these results, how do you think tail length in these cats are inherited? Show the genotypes for both the parents and the offspring to support your answer.

In mice, the ability to run normally is a dominant trait (R) In mice, the ability to run normally is a dominant trait (R). The recessive trait (r) causes mice to run in circles only. Black hair (B) is dominant over brown hair (b). Write the genotype of a mouse that is heterozygous for both traits.

In mice, the ability to run normally is a dominant trait (R). The recessive trait (r) causes mice to run in circles only. Black hair (B) is dominant over brown hair (b). What are the possible allele combinations for a mouse that is heterozygous for both traits?

Does this pedigree depict a dominant trait or a recessive trait?

What are the genotypes of individuals 1 and 2 of generation I?

Write the genotype of the colorblind men in this pedigree.
