A change in a DNA sequence is called a

Mutations that can be passed down to offspring occur in what kinds of cells?
somatic/body cells

gametes/sex cells
none of these; mutations are never passed down.

recombination
sexual reproduction
Sometimes, an organism can reproduce through mitosis. An example is the paramecium. What kind of reproduction occurs when an organism splits into two identical cells?
sexual reproduction
asexual reproduction
multicellular reproduction

phenotype
homozygous
dominant
Having different alleles for a trait
phenotype
homozygous

What do the letters INSIDE a Punnet square represent?
the genotype of the father and mother
the phenotype of the father and the mother
the possible genotype(s) of the offspring

Camelias are flowers grown in South Mississippi. They come in many different colors. If a camelia flower is heterozygous for red and white traits, and neither trait is dominant, which word would describe this pattern of inheritance?
codominance
incomplete dominance
multiple alleles
simple dominance
For a certain breed of chicken, the trait for color is controlled by codominance. A purebred black chicken (B) is crossed with a purebred white chicken (W). The offspring are 100% black and white checkered color. What is this pattern of inheritance called?
incomplete dominance
codominance
multiple alleles
simple dominance
Traits that are carried on the X or Y gene are inherited differently by males and females. What are these traits called?
incomplete traits
codominant traits
sex-linked traits
The intentional breeding of organisms to produce offspring with specific traits is called
inbreeding
specific breeding
selective breeding
genetic engineering
What term describes the insertion of a gene from one organism into the DNA of another organism?
recombination
crossing over
gene splicing
selective breeding
What is the correct definition of gene therapy?
the intentional mating of certain organisms to produce a specific trait
the insertion of a gene from one organism into the genome of another species
replacing non-working cells with cells that have been genetically altered
There are many factors that can affect gene expression. Some of these factors include temperature, light exposure, drugs, and chemicals. What are these factors called?
genetic factors
environmental factors
selection factors
expression factors

Darwin studied finches on the Galapagos Islands. He noticed that their head and beak structures were different. Why were these structures different?
The structures were different because the birds were different species.
The structures were different because there were different sources of food available for them to eat
The structures were different because of interbreeding
