Suppose a geneticist uses a three-point testcross to map three recessive, linked hummingbird wing-shape mutations called tk, r, and s, where tk is associated with thick wings, r is associated with round wings, and s is associated with sharp wings. He first crosses homozygous sharp birds to homozygous thick, round birds. Next, he testcrosses the F1 progeny to thick, round, sharp birds. He obtained the results shown. Given this data, label the progeny phenotypic classes as either parental, single crossover...

Suppose a geneticist uses a three-point testcross to map three recessive, linked hummingbird wing-shape mutations called tn, f, and b, where tn is associated with thin wings, f is associated with flat wings, and b is associated with blunt wings. He first crosses homozygous blunt birds to homozygous thin, flat birds. Next, he testcrosses the F1 progeny to thin, flat, blunt birds. He obtained the results shown. Given this data, label the progeny phenotypic classes as either parental, single crossover...

Question 1, Part 2: A student crossed two flies and collected Fl progeny. The first parental fly was homozygous for two recessive mutations - yellow body (y) and bent wings (b), while the other parental was homozygous for the wild- type alleles - black body (Y) and straight wings (B). All of the F1 progeny had straight wings and black bodies. He did a testcross between the yy bb parent and the F1 progeny, and observed the following classes in...
