Genetics

What is genetics?

• Studying how traits are passed from offspring to parent.
• Studying how animals interact with each other.
• Studying how traits are passed from parents to offspring.
• Studying how objects reproduce.

What is heredity?

• The passing of traits from offspring to parents.
• The passing of traits from parents to offspring.
• The passing of traits from animals to plants.
• The passing of traits from grandparents to grandchildren.

What are genes?

• Instructions for a particular trait.
• Instructions for a chromosome.
• Instructions for the nucleus.
• Instructions for molecules.

What are alleles?

• Different forms of the cell.
• Different forms of the nucleus.
• Different forms of a gene.
• Different forms of a body.

What are dominant alleles?

• The trait that will be hidden by the other type of allele.
• The trait that will always show up when present.
• The trait that will be masked by the other type of allele.
• The trait that will always be controlled when present.

What are recessive alleles?

• The trait that will always show up when present.
• The trait that will always control the other type of allele.
• The trait that will hide the other type of allele.
• The trait that will be hidden by the other type of allele.

What is a genotype?

• The genetic makeup which is represented by two numbers.
• The genetic makeup which is represented by two letters.
• The physical form of a gene.
• The appearance of an organism.

What is a phenotype?

• What you can physically see.
• What you cannot see.
• The genetic makeup.
• The two letters that represent the forms of the trait.

What is a heterozygous genotype?

• When the two alleles for a trait are the same.
• When the two alleles for a trait are similar.
• When the two alleles for a trait are the continuous.
• When the two alleles for a trait are different.

What is a homozygous genotype?

• When the two alleles for a trait are the same.
• When the two alleles for a trait are different.
• When the two alleles for a trait are similar.
• When the two alleles for a trait are continuous.
