What is the role of DNA in genetic inheritance?
DNA carries genetic information that determines an organism's traits and is passed from parents to offspring.
Which of the following best defines a gene?
A gene is a segment of DNA that codes for a specific protein or trait.
How does meiosis contribute to genetic diversity?
Meiosis creates gametes with different combinations of alleles, increasing genetic variation in offspring.
What is a phenotype?
A phenotype is the observable physical or biochemical characteristics of an organism as determined by both genetic makeup and environmental influences.
Which process results in the formation of gametes?
Gametes are formed through the process of meiosis, which reduces the chromosome number by half.
What does homozygous mean in terms of alleles?
An organism is homozygous when it has two identical alleles for a particular gene.

What is genetic drift?
Genetic drift is a mechanism of evolution involving random changes in allele frequencies in a population.
What is the significance of a Punnett square?
A Punnett square is used to predict the probability of an offspring having a particular genotype.
Which term refers to an organism’s complete set of DNA?
The genome refers to the complete set of genes or genetic material present in a cell or organism.
