As part of a lab experiment, you create a two-locus cross between two plants, and you expect to see a 9:3:3:1 ratio of offspring. You determine the phenotype for 160 offspring, and find the proportions 89:51:9:10. If you use a chi-square test to determine whether the offspring do indeed fit this pattern, how many degrees offreedom would the test have?

b.) 160 miles on a 5 gallons car

step-by-step explanation:

240/10=24 miles/gallon

160/5=32 miles/gallon

30/1=30 miles/gallon

168/6= 28 miles/gallon

32 miles/gallon is the most amount, so this is the best.

a

step-by-step explanation:

the denominator cannot be the same as one of the factors.

8 denominator times 2 denominator = 16

and 7 numerator time 11 = 77

77/16= 77/16 ( they cannot be further simplified)
