In a particular species of guppy, tails can either be long or short and either feathered or straight. A cross between a true-breeding long, feather-tailed male guppy and a true-breeding short, straight-tailed female guppy produces progeny that all have short, straight tails.
a) express the genotypes of the adults in the cross and the genotypes of all the progeny.
b) determine the phenotypic frequencies of the progeny in an F2 generation.
c) a mating between a short feather-tailed female and a short, straight-tailed male from the F1 generation produces
30 short, straight-tailed guppies; 42 short, feather-tailed guppies; 10 long, straight-tailed guppies; and 14 long, feather-tailed guppies.
Analyze the data using the chi-squared fit test to determine if the frequencies of phenotypes are what would be expected from this cross
