Chapter 19, Problem 3AWK

Summary Introduction

To review:

Each parent is able to contribute only a single allele of each gene to his/her offspring, rather than both alleles.

Introduction:

According to Mendel's law, each individual has two factors for each trait one of which they get from each parent. Depending on the type of information they get from their parents, they are divided into two categories: homozygous and heterozygous. An individual is said to be homozygous for the trait if it is carrying identical factors. If the two different factors have different information then the individual is said to be heterozygous. Alternative forms of a factor called as alleles. An individual contains two alleles for each trait, one from each parent (that is one from female and one from male parent).
