Genetics Test Review

Question Answer
Heredity Is the passing of physical characteristics from parents to offspring
Trait A characteristics that an organism can pass on to its offspring through its genes, such as stem height or seed color
Genetics The scientific study of heredity
Fertilization The process in which an egg cell and a sperm cell join to form a new organism
Purebred An offspring of many generations that have the same trait
Gene A segment of DNA on a chromosome that control a trait
Alleles Are the different forms of a gene
Dominant Allele Is one whose trait always shows up in the organisms when the allele is present.
Recessive Allele Is hidden whenever the dominant allele is present
Punnet Square Is a chart that shows all the possible outcomes of a genetic cross, and to determine the possibility of a particular outcome
Phenotype An organism's physical appearance, or visible traits
Genotype An organism's genetic makeup, or allele combination
Homozygous An organism that has two identical alleles for a trait
Heterozygous An organism that has to different alleles
Codominance A condition in which neither of two alleles of a gene is dominant or recessive. Both alleles are expressed in the offspring.
Meiosis Is the process by which chromosome pairs separate and are distributed to two different cells. The resulting sex cells have half the number of chromosomes as other cells in the organism.
Mutation A change in a gene or chromosome
SS or Ss or ss Genotype
Smooth pods or Pinched pods Phenotype
Some alleles are _____________, while other alleles are _________________. dominant, recessive
An organism's traits are controlled by the ______________ inherited from its parents. Alleles
Probability Is the likelihood that a particular event will occur
Hybrid An organism that has two different alleles for a trait (Heterozygous)
True or False? The allele that each parent will pass on to its offspring is based on probability. True
True or False? In codominance, the alleles are both dominant and recessive . False (it is neither)
Chromosome Theory of Inheritance States that genes are carried from parents to their offspring on chromosomes.
Chromosomes contains DNA that carries genetic information.
