In certain parts of Africa where malaria is prevalent there is an apparent advantage to being heterozygous for the recessive allele that causes sickle-cell anemia. Suppose a couple, both heterozygous for this allele, plans to have four children. What is the probability that all four will be heterozygous for the sickle-cell allele (assuming that none are from multiple births)? Explain how they can determine this using a Mendelian cross.

- how do plants integrate diverse signals into appropriate cellular and developmental responses to abiotic stress? I am aware of how they work in isolation e.g response to temperature, light, salinity, drought, nutrients and toxins, but not how the signalling occurs simultanously i.e transcription factors or ezymes present in two systems at once protecting the plant from both things.arrow_forwardtended Response (F24) O 3:58:01 remai Use the table below to construct a phylogenetic tree for a group of alien organisms found on the planet Kepler 22B by the astronomer D. Liscious. Ph.D. The common ancestor of all these organisms was green, silicon-based, with 2 legs, 4 dataports, 1 sex, and did not possess powered flight, x-ray vision, or interdimensional awareness. Assume the hypothesis of parsimony is valid and that all taxa are extant except for Taxon A, which is extinct. (10 pts) You should draw your tree on a piece of paper. Then, take a photo of it, save as a file, and upload it here. Please make sure your tree is neat and easy to read. Table 1. Kepler 22B taxonomic diversity with derived characters.

This might mean that, due to the rain shadow effect, the windward sides of mountains might be wetter, while the leeward sides of mountains might be drier. Using what you know about plant taxonomy and ecological relationships, propose a justified, ecological hypothesis on how plant community composition would change on each side of the mountain. Your answer should contain two parts: The hypothesis and the ecological justification addressing the bold points above.arrow_forwardExplain why homologies are used in constructing phylogenetic trees (2 pts).
