When One Gene Overshadows Another
Question: Alelle
Answer: One or two mor forms of a gene
Question: Carrier
Answer: Organisms whose gnome contains a gene for a certain trait or disease that is not expressed in the organism's phenotype.
Question: Codominance
Answer: A heterzygous genotype that equally expresses both traits from both alleles.
Question: Genotype-
Answer: The genes that are present in the DNA of an organism.
Question: Homozygous
Answer: A genotype that either has 2 uppercase letters or 2 lowercase letters.
Question: Cross
Answer: Mating of 2 organisms
Question: Crossing Over
Answer: Exchange of chromosome segments between homelogous chromosones during Miosis
Question: Phenotype
Answer: How a trait physically shows up in an organism.
Question: Alleles-
Answer: When one allele masks the effect of another that allele is called dominant while the other is called recessive.
Question: Dominant genes
Answer: one gene overshadows the other.
Question: Recessive Genes
Answer: the gene that is overshadowed by a dominant gene.
Question: Gene
Answer: Specific region of DNA that codes for a particular protein
Question: Genetics
Answer: Study of heredity patterns and variation of organisms
Question: Genome
Answer: All of an organism's genetic material
Question: Incomplete Dominance
Answer: Heterzygous phenotype that is a blend of the two homozygous phenotypes
Question: Karyotype
Answer: Image of all the chromosones in a cell
Question: Law of Independent Assortment
Answer: Mendel's second law stating that allele pairs separate from one another during gamete formation
Question: Law of Segregation
Answer: Mendel's first law stating that organisms inherit 2 copies of each gene from parent
Question: Monohybrid Cross
Answer: Cross or mating between 2 organisms that involve only pair of contrasting traits
Question: Pedigree
Answer: Chart of phenotypes and genotypes in a family that is used to determine whether an individual is a carrier of a recessive allele
Question: Polygentic Trait
Answer: Trait that is produced by 2 or more genes
Question: Probability
Answer: Liklihood that a particular event will happen
Question: Punnet Square
Answer: model for predicting all possible genotypes resulting from a cross or mating
Question: Purebred
Answer: Type of organism whose ancestors are genetically uniform
Question: Sex Linked Genes
Answer: Gene that is located on a sex chromosone
Question: Test Cross
Answer: Cross between an organism with unknown genotype and an organism with a recessive genotype
Question: Trait
Answer: A characteristic that is inheritied
