Mendelian Genetics

Front

Which trait of a dog is inherited from its parents?

Back

the color of its fur

Front

How will a cross between two homozygous parents, one dominant (AA) and one recessive (aa), influence future generations?

Back

Although the next generation will all show the dominant trait, the offspring will all be heterozygous and increase the chances of future variation.

Front

A couple has three brown-eyed children. The parents are brown-eyed (Bb). The allele for brown eyes is dominant over the allele for blue eyes. They believe the fourth child they have will be blue-eyed. What is the probability of having a blue-eyed child?

Back

They have a 25% chance of having a blue-eyed child.

Front

In a cross between two chickens with straight feathers, what percentage of the offspring can be expected to have frizzled feathers?

Back

0%
