BISC 120 EXAM Study Guide| Study terms
and Questions with Verified Answers
Cells - ✔✔What makes up living organisms
Prokaryotic Cell - ✔✔Most basic type of cell
Eukaryotic Cell - ✔✔advanced/complex cell
Blending Inheritance - ✔✔the idea that genetic material contributed by the two parents
mixes in a manner analogous to the way blue and yellow paint makes green
Particulate Inheritance - ✔✔parents pass on discrete heritable units (genes) that retain their
separate identities in offspring
Gregor Mendel (1822-1884) - ✔✔Scientist known as the father of genetics. Discovered some
of the fundamental laws of inheritance. Not recognized until after death. Pea plant experiments
# of human chromosomes - ✔✔23 pairs, 46 total
Alleles - ✔✔different version/type of same gene
Genes - ✔✔The scientific term for heritable factors. Gregor Mendel
Law of Segregation - ✔✔Two alleles for a heritable factor segregate during gamete
formation and end up in different gametes
, Gamete - ✔✔Reproductive cell
Homozygous - ✔✔Same alleles (PP,pp)
Heterozygous - ✔✔Different alleles (Pp). Show the trait of dominate allele
Genotype - ✔✔An organism's genetic makeup, or allele combinations.
Phenotype - ✔✔An organism's physical appearance, or visible traits.
Complete Dominance - ✔✔Heterozygote exhibits the trait associated with the dominate
allele but not recessive allele
Dependent Assortment - ✔✔the idea that different traits are inherited together, alleles from
different genes stay linked during gamete formation
Independent Assortment - ✔✔Alleles from different genes segregate independently of one
another during gamete formation, giving each trait an equal chance of being inherited with any
other trait. Gregor Mendel
Incomplete Dominance - ✔✔Heterozygous individuals appear to blend
Codominance - ✔✔Effects of both alleles are apparent in a heterozygote. Ex. Blood Type
DNA - ✔✔deoxyribonucleic acid
Scientists discovered DNA structure - ✔✔Watson and Crick (1953)
