6. Multiple Genes Interact To Determine The Phenotype.
Question: Multiple genes interact to determine the phenotype.
Answer: Polygenic traits
Question: Two alleles are dominant, resulting in offspring that show both phenotypes.
Answer: Co-dominance
Question: One gene has several different forms, resulting in more than two phenotypes.
Answer: multiple alleles
Question: Two alleles are neither completely dominant nor completely recessive, resulting in a phenotype that is a combination of the two
Answer: incomplete dominance
Question: Cytokinesis is the division of the ________________.
Answer: cell/cytoplasm
Question: Identify all of the possible allele combinations in the gametes formed by a plant that is heterozygous for seed shape and seed color (RrYy).
Answer: rY & RY
Question: A gene that is expressed only in the homozygous condition.
Answer: recessive
Question:
Answer: -An approximately three-to-one ratio of black to brown coated mice in F2 is accounted for by the black allele being dominant over the brown allele.
-The F1 male produced two kinds of sperm, half carrying an allele for black coat color, and half carrying an allele for brown coat color.
Question: In rabbits, the brown (agouti) coat color is dominant and black coat color is recessive.
Which of the following includes all of the possible genotypes for brown rabbits.
Answer: AA, Aa
Question: What is the expected phenotypic ratio in a cross between 2 pink flowered plants when the trait shows intermediate inheritance?
Answer: 1:2:1
