Question

Oz is inhabited by many unique creatures. In vertebrates, a dominant gene (A) creates the ability to think and speak. You may know of a famous Animal - the Lion. The recessive gene (a) is found in animals with which you are most familiar. Non-talking beasts like Toto are animals. Also found in the beasts are sections of DNA that create the ability to walk on two legs (B) and a recessive trait for walking only on four (b). The ability to walk on two legs is only expressed in Animals who can also speak! What are the possobile phenotypes of offspring from this cross: AaBb X aaBb? Please include a punnet square.

Explanation / Answer

Answer:

Based on the given information, for the unique creatures that have inhabitedd Oz, the alleles are:

Allele A (dominant) - ability to think and speak

a (recessive) - Non talking beasts

B (dominant) - ability to walk on 2 leegs

b (recessive) - ability to walk only on 5 legs

The punnett square for the cross AaBb x aaBb is as below:

The ratio of phenotype based on the punnett square is 3:3:1:1

aB ab aB ab AB AaBB AaBb AaBB AaBb Ab AaBb Aabb AaBb Aabb aB aaBB aaBb aaBB aaBb ab aaBb aabb aaBb aabb
