Answer part 3 and part 4. all details are included. aslo show steps when doing the chi sqaure test
the following data set a summarizes f2 numbers from a cross between two, true-breeding drosophila strains (p generation), which differ with respect to two traits. the gene alleles can be dominated or recessive, and autosomal or x-linked.
set a
curved wings, males > 281
wild type, males > 873
red eyes, curved wings, males > 301
red eyes, males > 868
curved wings, females > 575
wild type, females > 1651
1. name the classes and assign genetic symbols to the genes and allies involved. for example, if you suspect an x-linked trait, make it xr+ or xr. if it is autosomal then r and r+.
2. produce a genetic hypothesis about the mode of inheritance of the genes from your data set. for instance, the allele for yellow eyes is x-linked and recessive and the allele for long legs is autosomal dominant. include the expected phenotype ratios in the p, f1, f2 generations. (note: it would be simpler to treat each gene separately, and formulate a genetic hypothesis for each gene).

Melissa lives in a town called greendale. she discovers that when she lights a match and holds it near her kitchen faucet, the little flame grows into a larger fire. melissa is surprised because she thought the water would extinguish the flame rather than ignite it further. her mother tells her that the water might be contaminated with dissolved methane, a primary component in natural gas. melissa investigates the matter and finds that cases of methane contamination started shortly after a company began fracking for natural gas in the area. based on this information, which three statements are plausible consequences of fracking in greendale?

Amniocentesis is a process in which amniotic fluid is taken from the mother's womb to identify any genetic abnormalities in the fetus. how would the discovery of the human genome contribute to this process?

Is a measure of the resistance to flow. a high liquid has a high resistance to flow and flows slowly. the ancients thought everything in the world was made of 4 we now know that there are 94 naturally occurring and scientists have created another 24 i am certain they will create even more. honey flows slowly because it has a high to flowing. a can be separated by physical means because it contains more than one pure substance and 2 pure substances are not chemically bonded to each other. a cannot be separated by physical means. all matter is made up of all elements are with the same number of protons. if it is just a single or many bonded together, if all of them have the same number of protons, it is an element. in a piece of pure iron metal, all the are joined together, that piece of iron metal is called elemental iron. a single of iron is called elemental iron. a mixture has differences from place to place. we might need a microscope to see them or they might be obvious to the unaided eye. there are surfaces separating it into different phases. a mixture is the same everywhere. it is uniform. there are no surfaces separating it into different phases. if different kinds of atoms (different elements) are bonded together by their electrons, it is called a there are physical means of to isolate the different pure substances in a mixture and there are chemical means of to isolate the different elements in a compound. 1. element 2. compound 3. mixture 4. heterogeneous 5. homogeneous 6. pure substance 7. atoms 8. separation 9. viscosity 10. resistance
