What is the basic unit of heredity?
Chromosome
Gene
DNA
Protein
Explain the difference between dominant and recessive alleles in Mendelian genetics.
Dominant alleles mask the expression of recessive alleles.
Dominant alleles are always lethal, while recessive alleles are not
Dominant alleles are only found in males, while recessive alleles are only found in females
Recessive alleles are always more common than dominant alleles
What is the difference between genotype and phenotype?
Genotype is the genetic makeup, while phenotype is the physical characteristics.
Genotype is only relevant for plants, while phenotype is only relevant for animals
Genotype refers to physical characteristics, while phenotype refers to genetic makeup
Genotype and phenotype are the same thing
Give an example of a hereditary trait and explain how it is passed down from parents to offspring.
Hair texture - It is passed down from parents to offspring through the sharing of hair products
Height - It is passed down from parents to offspring through the influence of the moon's gravitational pull
Example: Eye color - It is passed down from parents to offspring through the inheritance of specific genes that determine the production of melanin in the iris.
Eye color - It is passed down from parents to offspring through the inheritance of specific fashion trends
What is the function of DNA in the context of genetics?
Regulates body temperature
Produces energy for the cell
Carries genetic information and instructions
Aids in digestion
Explain the role of genes in determining an organism's traits.
Genes have no impact on an organism's traits
Genes only determine physical appearance, not other traits
Genes are only responsible for the organism's behavior, not its physical traits
Genes contain the instructions for building and maintaining an organism's cells and tissues, which ultimately determine its traits.
How many chromosomes are typically found in a human somatic cell?
50

Describe how inheritance of sex-linked traits differs from other genetic traits.
Sex-linked traits are only found in males, while other genetic traits are found in both males and females.
Sex-linked traits are determined by environmental factors, while other genetic traits are determined by genes.
Sex-linked traits are determined by genes located on the sex chromosomes, while other genetic traits are determined by genes located on autosomes.
Sex-linked traits are only passed down from the mother, while other genetic traits are passed down from both parents.
What is the relationship between chromosomes and inheritance?
Inheritance is determined by the environment, not chromosomes
Chromosomes are only found in plants, not animals
Chromosomes contain the genetic information that is passed down from parents to offspring.
Chromosomes have no impact on inheritance
Explain the concept of genetic recombination during meiosis.
The process by which genetic material is duplicated during meiosis.
The process by which genetic material is lost during meiosis.
The process by which genetic material is exchanged between non-homologous chromosomes during mitosis.
The process by which genetic material is exchanged between homologous chromosomes during meiosis.
