Genetics CERTIFICATION GUIDE
FOR 2025/2026 TESTS|MOST COMMON
QUESTIONS WITH CORRECTLY VERIFIED ANSWERS
(LATEST QUIZZES) |ALREADY A+
GRADED|GUARANTEED PASS
codominance - both alleles are fully expressed (red and white blotches on flower)
incomplete dominance - phenotype is a blend of both alleles (pink flower)
pleiotropy - A single gene having multiple effects on an individuals phenotype (ex. cystic
fibrosis)
epistasis - a gene at one locus alters the phenotypic expression of a gene at a second
locus (ex. mouse hair)
polygenic inheritance - An additive effect of two or more genes on a single phenotypic
character (ex. skin color)
pedigree - A chart or "family tree" that tracks which members of a family have a
particular trait
examples of recessive disorders - albinism, cystic fibrosis, sickle cell
examples of dominant disorders - Achondroplasia, Huntington's disease
nondisjunction - Error in meiosis in which homologous chromosomes fail to separate.
aneuploidy - the presence of an abnormal number of chromosomes in a cell (ex. Down
Syndrome)
trisomic zygote - has three copies of a particular chromosome
monosomic zygote - has only one copy of a particular chromosome
