The study of genetic mutations
Who is known as the Father of Genetics?
Charles Darwin
Gregor Mendel
James Watson
Francis Crick
What are genes?
A type of chromosome
A segment of DNA that codes for a trait
The entire DNA in a cell
Proteins that determine traits
What is DNA?
A single-stranded molecule
A type of protein
A double helix molecule
A cellular organism
What is a chromosome?
A cell division process
A type of gene
A protein structure
Condensed DNA
How many chromosomes do humans have?
23
46
92
64
What is an allele?
A type of chromosome
A form or variation of a gene
A genetic disorder
A physical trait
What does the genotype of an organism represent?
The physical appearance of the organism
The genetic make-up of the organism
The dominant genes only
The environmental factors affecting the organism
What is a phenotype?
The genetic make-up of an organism
The environmental influence on an organism
The physical appearance of an organism's trait
The recessive genes in an organism
How do dominant genes behave in comparison to recessive genes?
Dominant genes are always hidden by recessive genes
Dominant genes mask recessive genes and always express themselves
Recessive genes mask dominant genes
Dominant genes have no interaction with recessive genes
What happens to recessive genes when they are present with a dominant gene?
They are expressed instead of the dominant gene
They blend with the dominant gene
They mask the dominant gene
They are hidden in the presence of a dominant gene
What does the term "Homozygous" refer to?
Two different genes
A model to show the possible gene combinations
A photograph of chromosomes
Two of the same genes
What is a Punnett Square used for?
To determine if an individual is male or female
To detect chromosomal disorders
To show the possible gene combinations from a genetic cross
To describe two different genes
What does "Heterozygous" mean in genetics?
A photograph of chromosomes
Two of the same genes
One dominant and one recessive gene
A model to show the possible gene combinations
What is a Karyotype?
A model to show the possible gene combinations
Two of the same genes
A photograph of chromosomes
One dominant and one recessive gene
Which of the following is true about a Karyotype?
It can only determine if an individual is male or female
It is used to show the possible gene combinations from a genetic cross
It is a model to describe two different genes
It can detect chromosomal disorders
What is the purpose of selective breeding?
To create a family tree of organisms
To manipulate DNA with technology
To mate two organisms with desirable traits for a specific outcome
To represent females on a pedigree chart
What does genetic engineering involve?
Tracing a family trait through multiple generations
Mating two organisms with desirable traits
Manipulating DNA with technology, such as inserting a gene of interest
Representing females on a pedigree chart
What does a pedigree chart show?
The process of inserting a gene of interest
The individuals who do breeding and farming
The representation of females by circles
A family trait through multiple generations and which individuals are carriers of the trait
How are females represented on a pedigree chart?
By squares
By circles
By triangles
By rectangles
What symbol is used to represent males on a pedigree chart?
Squares
Circles
Triangles
Hexagons
What is a carrier in genetic terms?
An individual who shows the trait in their phenotype
An individual who is affected by a mutation
An individual who does not have the gene present in their genotype
An individual who is unaffected in phenotype but has the gene present in their genotype
What causes a mutation?
Consistent DNA replication
Random change in DNA
Lack of variation
Stable environmental conditions
Which of the following can cause a mutation?
Exercise and diet
Sleep and meditation
Chemical exposure, radiation, UV, x rays
Reading and writing
