Directions: Black is the DOMINANT fur color for rabbits and white is the recessive. B stands for the black allele and b represents the white allele. A white rabbit would have a genotype of bb and a black rabbit could have a genotype of BB or Bb.

Who was Gregor Mendel? Check ALL that apply.
He is known as the father of modern archaeology.
He was a monk who changed the way people thought about inheritance.
His experiments provided evidence that each parent gives one set of instructions to their offspring.
He is well known for his experiments on tomato plants.
Select ALL of the follwoing that are true about Sexual Reproduction.
fish, amphibians, and mammals can reproduce this way
offspring is produced by only ONE parent
it is more time intensive
specific forms include budding, fragmentation, and binary fission
offspring are unique and look differnt from parents
