Question

the following describes which process? when the phenotypic expression of a gene at one locus alters that of a gene at another locus. epistasis codominance sex - linked genes pleiotrophy question 6 1 pts the genetic constitution of an individual is known as the ; while the physical expression of the genes is known as the.

Explanation:

• For the first question:
• Epistasis: It is when one gene affects the phenotypic expression of another gene at a different locus.
• Codominance: Refers to a situation where two alleles of a gene are both expressed in the phenotype (e.g., in blood types, AB blood shows both A and B antigen expressions).
• Sex - linked genes: Genes located on sex chromosomes (usually X - chromosome in humans) and their inheritance is related to the sex of the organism.
• Pleiotrophy: One gene has multiple phenotypic effects.
• For the second question:
• The term for the genetic constitution of an individual is “genotype”. It represents the set of genes an organism has.
• The physical expression of the genes is called “phenotype”. It is what we can observe (e.g., eye color, height in some cases).

Answer:

• First question: Epistasis
• Second question: genotype; phenotype
