WorksheetsInheritable Genetic Variations
Total questions: 15
Worksheet time: 8mins
The process in sexual reproduction where chromosomes can swap sections during cell division?
recombination
meiosis
mitosis
asexual reproduction
Environmental factors can cause this to occur in genes?
mutations
replication
duplication
elimination
The variation and distribution of traits observed depends on two factors?
physical and environmental
physical and genetic
genetic and environmental
environmental and chemical
This process creates new genetic combinations and therefore more genetic variation?
phosphorylation
mitosis
transcription
cell division (meiosis)
What are three pieces of evidence that inheritable genetic variations result from?
new genetic combinations through meiosis, errors in DNA replication, and mutations from environmental factors
errors in DNA replication, genetic combinations through mitosis, and mutations from chemical exposure
mutations from bacteria, errors in DNA translation, and genetic combinations through phosphorylation
errors in DNA transcription and new genetic combinations from DNA methylation
Insertions or deletions of DNA nucleotides can cause this?
transcriptions errors
meiosis
replication errors
cell division
What are among some specific environmental factors that alter genetic variations?
drugs, radiation, and bacteria
oxygen, sugar, and carbon dioxide
fertilizer and antibiotics
chemicals, sunscreen, and aloe
What cells does meiosis occur in?
egg and sperm (sex cells)
kidney cells
somatic cells (body cells)
skin cells
Process where double-stranded DNA molecule is copied to produce two identical DNA molecules?
DNA transcription
DNA translation
DNA methylation
DNA replication
Environmental factors can cause mutations here?
genome
chromatids
genes
centrosome
The mutations from environmental factors can be these two things?
inviable and not inherited

inviable and inherited
viable
Replication errors in DNA can result from these two specific changes to DNA nucleotides?

transversion and insertion
insertion and deletion
substitution and inversion
When nucleotides are added to a genetic sequence?
deletion
insertion
substitution
conversion
When DNA nucleotides are removed from a genetic sequence?
translocation
insertion
elimination
deletion
Environmental factors can affect this of traits, or how they are portrayed?
expression
observation
variation
distribution
