EXTRA DYHBRIDS
1. Alien Genetics: A is dominant for Slimy Skin, and a is recessive for dry skin. H is dominant for Green skin, and h is recessive for
brown skin. Mommy Alien is homozygous recessive for both traits and Daddy Alien is heterozygous for skin texture and homozygous
dominant for skin color. What is Mom’s genotype?______ Phenotype?__________ Dad’s genotype?_______

MEIOSIS REVIEW:
Draw/ label all of the phases of meiosis! Remember PMAT (for meiosis I) and PMAT again (for meiosis II). Be sure to show
crossing over and continue it all the way through. Start with 6 chromosomes (all a different color). Be sure to draw the spindle
when appropriate.
FILL IN
