Chromosomal Mutations Flashcards
Causes of Mutations in Sex Cells (3)
- Environmental factors
- Errors during DNA replication
- Random chance during cell division
disorders often caused by specific mutations in sex cells.
Genetic Disorders
- show effects even if only one copy is present.
- even if only one parent has it, the child will inherit it.
Dominant Mutations
- require two copies to show effects.
- if both parents have it, the child will inherit it.
Recessive Mutations
Down Syndrome, Alzheimer’s are examples of…
Dominant Mutations
Albinism, Color Blindness are examples of…
Recessive Mutations
can identify mutations in sex cells.
Genetic Testing
can inform individuals about potential risks for their children.
Genetic Testing
- changes in the structure or number of chromosomes.
- can have significant effects on an individual’s development.
Chromosomal Mutations in Sex Cells
can guide family planning decisions.
Genetic Testing
Examples of Chromosomal Mutations in Sex Cells (3)
- Down Syndrome
- Klinefelter Syndrome
- Turner Syndrome
can affect the genetic diversity of a population.
Mutation Rates
When there are high mutation rates…
high mutation rates = rapid evolution & genetic disorders
When there are low mutation rates…
low mutation rates = stagnation & reduced adaptability
visualizing chromosomes under a microscope to identify structural and numerical changes.
Karyotyping
