An experienced goldfish breeder receives 2 unusual male goldfish. One is black rather than gold and the other has a single fail fin rather than a split tail fin. The breeder crosses the black male to a female that is gold. She also crosses the single finned male to a female with a split tail fin. All the F1 have a split tail fin. She then crosses the black mail to F1 gold females and separately crosses the single finned male to a F1 split-finned females. The results of the crosses are shown below:Black Male X F1 gold femaleGold: 32Black: 34Single-finned male X F1 split finned femaleSplit Fin: 41Single Fin: 39a. What do the result of these crosses suggest about the inheritance of color and tail fin shape in goldfish?b. Is black color dominant or recessive? Describe your answer? Is single tail dominant or recessive? Explainc. Use chi-square analysis to test your heredity hypothesis for each trait?
