BIS 101 Lecture 14: Prokaryotic Gene Regulation

In plants, you want to know whether two loci, P and Q, are linked and if so, what their map distance is. You do a testcross with a P/p●Q/q plant and observe the following progeny. Based on this information, what are the genotypes of the parents?

a - PQ/pq x pq/pq

b - PQ/PQ x pq/pq

c - PQ/pq x PQ/pq

d - PQ/pq x pq/pq

e - pQ/Pq x pq/pq

A. What is cardiac output (Q), and how do we calculate Q? B)Describe the response of Q to incremental graded exercise. C) thendiscuss the contribution of the components of Q to changes observedduring exercise.
