Question

show process

Let's tie some of the concepts from last class together with a butterfly example STRIPE locus: WRR-0.7 WRY-1.0 ww-0.2 RY 0.7 0.2 TR) -P-0.8 How do we expect the freq. of R to change from this generation to the next? (p equation) Did AR) increase, decrease or stay the same? Why? To answer this, we want to know the expected f(R) at equilibrium (p-hat equation)

Answer 1

The frequency of 'R' will change from 0.8 in the present generation to 0.7 in the next generation.  

Ry 32 yy'ニ o.oy O. 2 be ct Rt+) Ο.dy (0.7). Oo31)(1). : 1. 1.1

The frequency of 'R' decreased in the next generation. Due to its decreased fitness in homozygous condition 'RR' which is 0.7 relative to 1 in case of 'RY' condition.
