You have discovered a rare, freshwater squid, D. longissimus,living in Lake Merritt. Further investigation reveals twotrue-breeding strains, one with blue spots and short tentacles, andone with yellow spots and long tentacles. In crosses between thetwo strains, the F1 offspring always exhibit long tentacles andyellow spots. When you cross the F1's, you found 168 with longtentacles and yellow spots, 55 with long tentacles and blue spots,62 with short tentacles and yellow spots and 22 with shorttentacles and blue spots. (please show all work)

A.What are the genotypes of the two original strains? Defineyour genetic symbols clearly.

B.) Using a chi-square test, compare the observed numbers ofprogeny with those expected from the cross.

C.) What conclusions can you draw from the results of thechi-square test?
