Chapter 7.5, Problem 40CQ

a.

Summary Introduction

To determine:

The calculation recombination frequency between $Trf$ and $d$ position by using the pooled data.

Introduction:

Recombination frequency is used to measure the genetic linkage. Recombination frequency is also used to create genetic linkage map. Basically recombination frequency is a frequency in which single chromosomal crossover will occur between two genes. Transferrin is a blood protein that is encoded by the transferrin locus $Trf$. In mice, the two alleles at this locus $Trf\text{and}Tr{f}^b$ are co-dominant and encode three types of transferrin. Dilution locus is also found on the same chromosome. (d) represent dilution that is recessive to $\left(d^{+}\right)$ allele for full color. Donald Shreffler conduct a series of cross to check the map distance between the transferrin locus and dilution locus

b.

Summary Introduction

To determine:

The cross that represent recombination in male gamete formation and the cross that represent recombination in female gamete formation

Summary Introduction

To determine:
