Genetics Introduction

According to the Law of Segregation, what two factors control a given characteristic? (choose both)

• one trait dominates the other

• these factors separate and go to different gametes

• each parent provides two genes that code for the same trait to their offspring

• children will always look like their father

How many copies of each trait does a parent have? How many do they donate to their offspring?

• 1;2

• 2;1

• 2;2

• 4;2

Which term is defined as: this trait masks the presence of another trait

• dominant

• recessive

• gene

• heterozygous

Which term is defined as: the trait that is masked by another trait

• dominant

• recessive

• gene

• heterozygous

Which term is defined as: a piece of DNA that is inherited and codes for one protein (one trait)

• genotype

• homozygous

• gene

• heterozygous
