gene correct answers a hereditary factor that determines (or influences) a particular trait
genome correct answers all of your DNA
allele correct answers a variant of a gene (chocolate and vanilla are variants of ice cream)
phenotype correct answers physical characteristics of an organism
dominant allele correct answers an allele that is fully expressed in the phenotype of a
heterozygote
recessive allele correct answers An allele that is masked when a dominant allele is present
Mendelian inheritance correct answers the view that heredity is based on nonblending, single-
particle genetic inheritance
diyhybrid cross correct answers looking at more than one trait at the same time
Principle of Independent Assortment correct answers genes for different traits can segregate
independently during the formation of gametes
multiple allele traits correct answers traits controlled by a single gene with more than two
alleles
Non-Mendelian Traits correct answers traits that are not determined by dominant and
recessive alleles and can involve more than one gene (polygenic traits)
Incomplete Dominance correct answers Individuals that are heterozygous will have a
phenotype that is intermediate in appearance (a blend of two phenotypes)
Codominance correct answers both alleles for a gene are fully expressed as a hybrid of both
traits
Polygenic Traits correct answers traits produced by two or more genes (ex: height)
Epistasis correct answers A type of gene interaction in which one gene alters the phenotypic
effects of another gene that is independently inherited.
sex-linked traits correct answers Traits controlled by genes located on sex chromosomes.
Karyotype correct answers A display of the chromosome pairs of a cell arranged by size and
shape.
Pleiotropy correct answers expression of multiple traits by a single gene. It needs to have
several characteristics dependent on it.
T/F Blood is based on the presence of antigens on the surface of the cell correct answers true
, T/F Type B blood has Type B antibodies as part of its immune system correct answers false
Type A blood can receive correct answers A or O
Type B blood can receive correct answers B or O
Type AB blood can receive correct answers A, B, AB, or O
Type O blood can receive correct answers O
Type O can donate to correct answers everyone
If you have type B blood your genotype is either correct answers BB or BO
How many genotypes possible in the ABO system correct answers 6 (AA, AO, BB, BO, AB,
OO)
If your father has type B blood (heterozygous) and your mother has type A blood
(heterozygous), what is the likelihood your blood type is A? correct answers 25%
Exceptions to Mendelian genetics correct answers single gene patters, multiple gene patterns,
environmental influences
single gene patterns include correct answers incomplete dominance, codominance, multiple
allelism, pleiotropy, sex-linked traits
Multiple gene patterns include correct answers polygenic traits
what is binary fission correct answers A form of asexual reproduction in which the parent
divides into two approximately equal parts
Cell Division Stages correct answers interphase, prophase, metaphase, anaphase, telophase,
cytokinesis
mitotic cell division correct answers consists of mitosis and cytokinesis. a cell divides to
produce two new daughter cells
meiotic cell division correct answers A form of cell division that includes only one round of
DNA replication but two rounds of nuclear division; This type of cell division makes sexual
reproduction possible. (meiosis followed by cytokinesis)
Ploidy correct answers number of sets of chromosomes in a cell
Haploid cells correct answers A cell having only one complete set of chromosomes. (gamete
or sex cells) (n)
Diploid Cells correct answers A cell containing two sets of chromosomes (2n), one set
inherited from each parent. (somatic cells) (2n)
