Genetics Test

How can you find the ratio of offspring?

• divide the number of recessive genes by the number of dominant genes

• divide the number of dominant genes by the number of recessive genes

• multiply the dominant and recessive genese

• add the dominant and recessive genes together

What happens when we cross two hybrid plants? (select all that apply)
