BIO 340 FINAL EXAM REVIEW; QUESTIONS
WITH DETAILED VERIFIED ANSWERS; ALREADY
GRADED A; 2025
Alleles - correct answer- Alternate forms of a gene
Autopolyploidy - correct answer- Multiple chromosome sets from
the same species
Autosomal - correct answer- Chromosomes that are NOT sex
chromosomes
Autosomal Dominant - correct answer- An affected individual has
one copy of a mutant gene and one normal gene on a pair of autosomal
chromosomes
Autosomal Recessive - correct answer- An affected individual has
two copies of a mutant gene on a pair of autosomal chromosomes
Central Dogma of Biology - correct answer- DNA -> RNA -> Protein
Centromere - correct answer- Area where the chromatids of a
chromosome are attached
, Chiasmata - correct answer- X-shaped regions where crossing over
occurs
Chromatids - correct answer- Two identical chromosomes that split
and contain the same genetic material
Codominance - correct answer- When heterozygotes express the
phenotype of both their alleles
Dihybrid Cross - correct answer- A cross between individuals that
have different alleles for the same gene (9:3:3:1 ratio)
Diploid - correct answer- Containing two complete sets of
chromosomes, one from each parent
Dominant - correct answer- An allele that masks a recessive allele
Epistasis - correct answer- Two separate genes control one trait, but
one gene masks the expression of the other gene
Euploidy - correct answer- Possessing a multiple of the basic
chromosome set
