BIO 100 Unit 3 UPDATED ACTUAL Exam
Questions and CORRECT Answers
Gene - CORRECT ANSWER - region of dna on a chromosome that determine traits
allele - CORRECT ANSWER - alternate form of the same gene (eye color)
dominant gene - CORRECT ANSWER - always expressed
recessive gene - CORRECT ANSWER - hidden or masked
homozy - CORRECT ANSWER - Having two identical alleles for a particular gene
hetero - CORRECT ANSWER - An organism that has two different alleles for a trait
non men - CORRECT ANSWER - Inheritance of traits that do not follow Mendelian
patterns.
polygenic trait - CORRECT ANSWER - trait controlled by two or more genes
karyotype - CORRECT ANSWER - A display of the chromosome pairs of a cell arranged
by size and shape.
P generation - CORRECT ANSWER - parent generation
f1 generation - CORRECT ANSWER - the first generation of offspring obtained from an
experimental cross of two organisms
, F2 generation - CORRECT ANSWER - offspring of the F1 generation
mendels - CORRECT ANSWER - law of dominance, law of segregation, law of
independent assortment
genotype - CORRECT ANSWER - genetic makeup of an organism
phenot - CORRECT ANSWER - An organism's physical appearance, or visible traits.
law of dominance - CORRECT ANSWER - In many traits one allele is dominant over the
other allele. The "weaker (recessive" allele is only expressed when it is paired with another
recessive allele
law of unit - CORRECT ANSWER - traits are controlled by a pair of factors (genes)
law of segregation - CORRECT ANSWER - Mendel's law that states that the pairs of
homologous chromosomes separate in meiosis so that only one chromosome from each pair is
present in each gamete
non mendelian traits - CORRECT ANSWER - - incomplete dominate
- codominance
- multiple alleles
-polygenic trait
multiple allele trait - CORRECT ANSWER - trait controlled by one gene with more than
two alleles
example:ABO blood type
polygenic trait - CORRECT ANSWER - trait controlled by two or more genes
