General Biology Genetics Review
1. What does incomplete dominance refer to?
- Answer: Incomplete dominance is a type of inheritance where neither of the two alleles is fully
dominant or recessive, resulting in offspring with a phenotype that blends the traits of both parents.
2. How is co-dominance defined?
- Answer: Co-dominance occurs when both alleles in a gene pair fully contribute to the phenotype of
an organism.
3. What is epigenetics?
- Answer: Epigenetics involves heritable changes in gene expression that can modify phenotypes
without altering the underlying DNA sequence, primarily through changes in chromatin structure.
4. What is a dihybrid cross?
- Answer: A dihybrid cross examines the inheritance of two distinct traits concurrently, involving
individuals that possess different alleles for the same gene.
5. What are multiple alleles?
- Answer: Multiple alleles refer to a gene that can have three or more different forms, which all
influence a single trait.
6. Define a pedigree.
- Answer: A pedigree is a graphical representation that maps out the occurrence of a genetic trait
across multiple generations within a family.
7. What signifies a sex-linked gene?
- Answer: A sex-linked gene is located on one of the sex chromosomes, predominantly the X
chromosome.
8. What is a karyotype?
