Textbook Question
Chapter 14, Problem 16TYU
SCIENTIFIC INQUIRY You are handed a mystery pea plant with tall stems and axial flowers and asked to determine its genotype as quickly as possible. You know that the allele for tall stems (T) Is dominant to that for dwarf stems (t) and that the allele for axial flowers (A) is dominant to that for terminal flowers (a).
(a) Identify all the possible genotypes for your mystery plant.
(b) Describe the one cross you would do, out in your garden, to determine the exact genotype of your mystery plant.
(c) While waiting for the results of your cross, you predict the results for each possible genotype listed in part a. Explain how you do this and why this is not called "performing a cross."
(d) Explain how the results of your cross and your predictions will help you learn the genotype of your mystery plant.

For practice construct a Genetic map with three genes in Arabidopsis plants. A short plant (hy) is recessive to tall plant (HY), a red flower (r) is recessive to white flower (R); and long pollen (po) is recessive to oval shaped pollen (PO). You can come up with arbitrary number of progenies for each class of offspring (follow the numbers like in Fig. 7.14)
( please help, I dont understand what/how to do this)

A pea plant with the genotype RrYYPpIiaa is crossed with a second pea plant with genotype RRyyPPiiAa where round seeds (R) are dominant to wrinkled (r), yellow seeds (Y) are dominant to green (y), purple petals (P) are dominant to white (p), inflated pods (I) are dominant to pinked (i), and axial flowers (A) are dominant to terminal (a). What is the probability that these two parental pea plants will produce an offspring with the following genotype RrYyPPiiaa?

- Let's do one more monohybrid cross. Suppose these is a gene in chickens that controls whether their eggs will be brown or white. Assuming that brown eggs (B) are dominant to white eggs (b), what are all of the phenotypes that would result from a cross between two chickens that are heterozygous for laying brown eggs? To get full credit for this question you will need to:a) List the parental genotypes and phenotypes.b) List the gametes produced by each parent.c) Do a punnet square. You can do this by inserting a 3x3 table.
