Summary Introduction

To determine:

A list of physical traits and try to determine the inheritance pattern of each trait.

Introduction:

Different traits in human beings or any organism have different characteristics that are determined by DNA and environmental agents. All the characters are determined by different inheritance pattern.

Explanation of Solution

There are some traits like hair color, skin color, eye color and height are polygenic traits, which is influenced by many traits as well as environment factors. These have continuous variation among individuals and there is no specific distinction.

Some traits such as blood groups are distinct and have a specific type for an individual. Based on the alleles, a person may have A, B, AB or O type blood group. Similarly, color blindness is a condition, in which a person is not able to distinguish between colours properly. It is a recessive condition, which is present in a smaller number of individuals.
