Select all answers that are correct.
The dominant allele is ALWAYS seen when a dominant allele is present
The recessive allele is ALWAYS seen when a recessive allele is present
TWO recessive alleles must be present for the recessive allele to be seen

PUNNETT SQUARE PRACTICE

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.

Pedigree 1 shows a family of parrots. One offspring shows the trait for blue feathers. (R = red feathers, r = blue feathers).

Do you think blue feathers is dominant or recessive? How did you know? Support your answer.

Create your own pedigree or make one up! You must show 3 generations.

Ideas on who to include: You, your parents, Aunts/Uncles, your grandparents, grandparents siblings, your great-grandparents. See mine below!
