Quiz Bank Question & Answers 2023 GRADED A+
Character correct answers A heritable and variable feature of an organism
Trait correct answers A variant of a character
Law of Segregation correct answers A Mendelian law of genetics stating that an organism inherits two
alleles of every gene, and these alleles segregate such that each gamete has only one of these alleles
Alleles correct answers Different versions of a gene, which can therefore code for different traits of a
character.
Complete dominance correct answers A type of dominance in which one allele variety, the dominant
allele, will always determine the trait if it is in the genotype, and the other, recessive allele, will only
determine the trait if no dominant alleles are present.
3:1 ratio correct answers The phenotypic ratio seen in a monohybrid cross when two individuals with
genotypes heterozygous for one trait are bred. This is due to the 1:2:1 ratio of homozygous
dominant:heterozygous:homozygous recessive.
Homozygous correct answers An organism with a pair of identical alleles. It is also known as true-
breeding
Heterozygous correct answers An organism with two different alleles. It produces gametes with
different alleles.
Phenotype correct answers The appearance and observable traits caused by the genotype
Genotype correct answers The genetic makeup of an organism.
Law of Independent Assortment correct answers The Mendelian law stating that alleles that are part of
different genes will separate independently, and therefore each allele combination should be treated
independently in a dihybrid or further cross.
Dihybrid cross correct answers A cross in which two traits are examined, and both individuals are
heterozygous for both traits
9:3:3:1 ratio correct answers The phenotypic ratio that will occur within a dihybrid cross
Incomplete Dominance correct answers A type of dominant in which neither allele is dominant and a
heterozygous genotype results in an intermediate or blended phenotype
Codominance correct answers A type of dominance in which each allele affects phenotype in a different
way. In this way, a heterozygous genotype results in the presence of both traits.
