Question 5 Assume you discovered two new genetic traits in drosophila caused by two different mutations. In the first trait, you can clearly distinguish that the flies can have either 2 or 3 stripes on their body. For the other trait, you can distinguish yellow bodies in some flies and white bodies in others. You hypothesize that the stripe trait is controlled by 1 gene (where 2 stripes (S) is dominant over 3 stripes (s)) and that a different gene determines the body color (where white (W) is dominant over yellow (w)). You hypothesize that the genes are on different chromosomes. You set out to test your hypothesis, by crossing F1 heterozygote (in other words, dihybrids) male and female flies. Below is a table as it appears in YOUR lab book. You have already indicated the number of flies you have obtained for each combination of phenotypes. Perform a chi²-test by completing the table below to determine if your data is consistent with your hypotheses. Provide your reasoning by showing…

QUESTION 11 Which of the following statements about RNA interference pathways and mechanisms is FALSE? O A Investigators can load RISC and/or RITS complexes with artificial, designed RNAS in order to specifically target and silence a gene of interest as a way to see what the effect of that gene is when its expression is silenced. O B. Only a small section of a small interfering RNA, called the 'seed' sequence, is actually used to identify nucleic acid targets that are to be silenced. OC. Eukaryotic RNA interference pathways do not regulate genes from the genome itself (i.e. endogenous genes), they only respond to external infection events such as invading viruses. The piRNA pathway processes small RNAS out of long noncoding RNA transcripts and is important for suppression of repetitive element movement in germ cells. OD. O E. The micro (n RNA pathway and the short interfering (si) pathways load small RNAS into RISC or RITS complexes.
