Chapter E, Problem 10P

Summary Introduction

To analyze:

The four allelic frequencies contributed to the child by probable father $\text{F1}$ in Problem $\text{7}$ are $\text{0}\text{.18, 0}\text{.23, 0}\text{.13, and 0}\text{.14}$.

From the given information,

a. Determine the combined paternity index for the four genes mentioned in this analysis.

b. Formulate a statement about the probable paternity of $\text{F1}$ based on this analysis.

Introduction:

DNA analysis can be used for identification of parents in sexually reproducing animals including humans. A child receives exactly one half of genes from the mother. Genetic testing can be used to reveal that one half of the genetic markers in the child match those of the mother. Genetic markers that are not maternal should have come from the father. To identify paternity, every non-maternal marker carried by a child must be carried by the father.
