A diploid yeast was ABD on one chromosome and abd on the other. The yeast cell underwent meiosis and the four genomes in the resulting tetrad were analyzed and determined to be: ABD, ABD, aBD and abd.
(a) For the moment, focus on the outcome regarding the number of B versus b genes. (Ignore D and d.) What is unexpected, regarding the number of gene types in the meiotic cells? Rationalize how this could have happened, assuming that this outcome had something to do with recombination.
(b) Is there a second "unexpected" outcome, and, if so, what is it? Assume that this second outcome occurred in a process that was linked to the first outcome, which happened with the B/b gene. Explain how they both might have occurred together.
(c) What is the name associated with the outcome: ABD/ABD/aBD/abd?

Every compound can be represented by a chemical formula. a chemical formula is the set of symbols showing the elements that make up a compound and their proportions. water’s chemical formula is h 2 2 o. that means a molecule of water contains two atoms of hydrogen and one atom of oxygen chemically bonded. a molecule is a group of two or more atoms bonded together. molecules can range in size from two to thousands of atoms. a molecule of a compound is the smallest unit of that compound. every molecule of water has all the physical and chemical properties of water. that’s because every molecule of water is made of the same elements in the same proportions: two hydrogen atoms and one oxygen! which of the following is a true statement? a every molecule of the same compound will have different properties. b every molecule of a compound has the same proportion of elements. c molecules can be physically separated into smaller units of a compound. d molecules cannot be represented by chemical formulae.

In german cockroaches, curved wing (cv) is recessive to normal wing (cv+). bill, who is raising cockroaches in his dorm room, finds that the frequency of the gene for curved wings in his cockroach population is 0.6. in his friend joe’s apartment, the frequency of the gene for curved wings is 0.2. one day joe visits bill in his dorm room, and several cockroaches jump out of joe’s hair and join the population in bill’s room. bill estimates that, now, 10% of the cockroaches in his dorm room are individual roaches that jumped out of joe’s hair. what is the new frequency of curved wings among cockroaches in bill’s room? 0.69 0.4 0.5 0.31 0.20
