You would like to know whether the progeny of a pair of mated fruit flies are distributed among the resulting four phenotypic classes in a 1: 1: 1: 1 ratio. you perform a chi-square test and obtain a p value of 0.04. assuming you have done the test correctly, select the best interpretation of this result. a. the phenotypic ratio is actually 9: 3: 3: 1 b. approximately 4% of the offspring lie outside the range of values expected for a 1: 1: 1: 1 ratio. c. the differences between the observed and expected counts are too large to be attributed to chance. d. the traits being studied are on separate chromosomes.

the correct answer is: the C option

The differences between the observed and expected counts are too large to be attributed to chance.

Explanation:

Tt is on this basis (p< 0.05) that the decision to reject the hypothesis of a 1:1:1:1 ratio is made. An expected frequency is a theoretical predicted frequency obtained from an experiment presumed to be true until statistical evidence in the form of a hypothesis test indicates otherwise.

the corpus luteum secretes estrogens and progesterone. the latter hormone causes changes in the uterus that make it more suitable for implantation of the fertilized ovum and the nourishment of the embryo. if the egg is not fertilized, the corpus luteum becomes inactive after 10–14 days, and menstruation occurs.

i hope this : )
