Central Dogma - Answer>> DNA -> RNA -> Protein
, theory that states that, in cells, information only flows from DNA to RNA to proteins
Gene - Answer>> The physical unit of heredity,
composed of a DNA sequence that is
transcribed and encodes a polypeptide
or another functional molecule.
Mutation - Answer>> The addition of genetic variation that increases the hereditary diversity of a population
Independent events - Answer>> The probability that one occurs does not affect the probability that the other occurs
Multiplicative Rule of Probability - Answer>> If two events are independent, then the probability that they both occur is given by p(A,B)=P(A)P(B)
True-breeding - Answer>> A group of identical individuals that always produce offspring of the same phenotype when mated with each other
Replicate Crosses - Answer>> Same cross repeated
Reciprocal Crosses - Answer>> determines whether a trait is sex linked. If autosomal, should be same ratio no matter which way cross is. If sex linked, there will be a difference in phenotype ratios Test Crosses - Answer>> Specific crosses to test hypotheses about genes.
Mendel's Law of Segregation - Answer>> a. The two copies of a gene separate equally during gamete formation, so that half of the gametes carry one member of the pair, and half carry the other member
b. During fertilization, gametes unite at random, i.e. they fuse without regard to which allele is carried by the other
Law of Independent Assortment - Answer>> During gamete formation, the segregation of alleles at one locus is independent of the segregation of alleles at another locus.
Dihybrid cross - Answer>> 9:3:3:1
Two-point test cross - Answer>> 1:1:1:1 ratio
Autosomal inheritance - Answer>> Transmission of traits carried on autosomes, which are chromosomes found in both males and females
Pedigree - Answer>> A diagram that shows the occurrence of a
genetic trait in several generations of a family
Autosomal Dominant Inheritance - Answer>> Only on copy of the abnormal gene is required for individual to be affected
Autosomal Recessive Inheritance - Answer>> Need 2 copies of
the damaged gene to inherit the problem-1 from the mother and 1
from the father
Homologous - Answer>> Chromosomes that have the same sequence of genes and the same structure
