Genetics Quiz

What is a monohybrid cross?

• A cross between individuals that involves one pair of contrasting traits.

• A cross between individuals that involves two pairs of contrasting traits.

• A cross between individuals that involves multiple pairs of contrasting traits.

What is the P generation in genetics?

• The first generation of offspring obtained from an experimental cross.

• The second generation of offspring obtained from an experimental cross.

• The first two individuals that mate in a genetic cross.

What is the law of segregation?

• Mendel's law that states that genes separate independently of one another in meiosis.

• Mendel's law that states that the pairs of homologous chromosomes separate in meiosis so that only one chromosome from each pair is present in each gamete.

• The likelihood that a possible future event will occur in any given instance of the event.

What is a test cross in genetics?

• The crossing of an individual of unknown genotype with a recessive individual to determine the unknown genotypes.

• A diagram that shows the occurrence of a genetic trait in several generations of a family.

• A condition in which both alleles for a gene are fully expressed.

What are sex-linked traits?

• A trait that is determined by a gene found on one of the sex chromosomes, such as the X chromosome or the Y chromosome.

• A characteristic of an organism that is determined by many genes.

• A condition in which a trait in an individual is intermediate between the phenotype of the individual's two parents because the dominant allele is unable to express itself fully.

What is a phenotype in genetics?

• The physical and physiological traits of an organism, which are determined by its genetic makeup.

• The genetic makeup, or set of genes, in an organism.

• The first two individuals that mate in a genetic cross.

What is a genotype in genetics?

• The physical and physiological traits of an organism, which are determined by its genetic makeup.

• The genetic makeup, or set of genes, in an organism.

• The first two individuals that mate in a genetic cross.

What is the law of independent assortment?

• Mendel's law that states that genes separate independently of one another in meiosis.

• Mendel's law that states that the pairs of homologous chromosomes separate in meiosis so that only one chromosome from each pair is present in each gamete.

• The likelihood that a possible future event will occur in any given instance of the event.

What is a dihybrid cross in genetics?

• A cross between individuals that involves two pairs of contrasting traits.

• A cross between individuals that involves one pair of contrasting traits.

• A cross between individuals that involves multiple pairs of contrasting traits.

What is the F1 generation in genetics?

• The first generation of offspring obtained from an experimental cross.

• The second generation of offspring obtained from an experimental cross.

• The first two individuals that mate in a genetic cross.
