Punnett Squares:
4. Nematodes( round worms) normally move in a snake-like motion. rr worms move only in circles and are called rollers. Use a Punnett square to predict the offspring when you cross heterozygous rolling (Rr) worms with worms taht are homozygous rollers (rr).
5. A recessive allele in tigers caused the white tiger (ww). If two normally pigmented tigers (W) are mated and produce a white offspring, what percentage of their remaining offspring would be expected to have normal pigmentation?
