◉ What is the difference between genetics and genomics? Answer:
Genetics is the study of individual genes and their effects on traits,
while genomics is the study of an organism's entire genetic makeup
and how genes interact with each other and the environment.
◉ What is the importance of family history in genetics? Answer:
Family history helps identify inherited conditions and can be
visualized using a pedigree chart.
◉ What does the term single nucleotide polymorphism (SNP) refer
to? Answer: A genomic variant at a single base position in the DNA.
◉ How are genome wide association studies (GWAS) used? Answer:
GWAS are used to advance knowledge in genomics by identifying
genetic variants associated with diseases.
◉ What is epigenetics? Answer: Epigenetics refers to changes in gene
expression that do not involve alterations to the DNA sequence, often
influenced by environmental factors.
, ◉ What is CRISPR technology? Answer: CRISPR is a gene-editing
technology derived from a natural defense mechanism in bacteria,
allowing for precise modifications in DNA.
◉ What is Mendelian inheritance? Answer: Mendelian inheritance
describes how genetic traits are passed from parents to offspring,
based on Gregor Mendel's work with pea plants.
◉ What are genetic mutations? Answer: Genetic mutations are
changes to a gene that alter its genetic code, which can be inherited or
occur spontaneously.
◉ What is a human karyotype? Answer: A human karyotype is a
picture of chromosome pairs, showing 23 pairs (46 chromosomes)
that can identify chromosomal abnormalities.
◉ What is the difference between genotype and phenotype? Answer:
Genotype refers to the genetic code, while phenotype refers to the
physical expression of those genes.
◉ What does heterozygous mean? Answer: Heterozygous refers to
having two different alleles for a trait.
◉ What does homozygous mean? Answer: Homozygous refers to
having two identical alleles for a trait.
