Definition
the passing of physical traits or characteristics from parents to their offspring
the process of producing two identical copies from one original DNA molecule
the building blocks of DNA (and RNA)
strands of DNA that are twisted together; 2 sister chromatids after replication
one-half of two identical threadlike strands of a replicated chromosome
a segment of DNA on a chromosome that codes for a specific trait
founder of modern science of genetics; famous for his pea experiments
an organism that always produces an offspring with the same form of a trait as the
purebred
parent
trait
a characteristic that an organism can pass on to its offspring through its genes
allele
the different forms of a gene like smooth/wrinkled seeds or tall/short height
Rosalind Franklin
famous woman scientist who used x-rays to photograph DNA molecules
James Watson & Francis Crick with Franklin's photographs, created a 3D model of DNA molecule
reproductive cells; mature male or female cells that unite with another of the
opposite sex to produce a fertilized cell; each contains 1/2 of the genetic material
sex cells
needed by the offspring
dominant
an allele whose trait always shows up in the organism when the allele is present
recessive
an allele that is masked when a dominant allele is present
genotype
an organism's genetic make up or allele combination
phenotype
an organism's physical appearance of a visible trait
diagram designed to predict an outcome of a particular cross or breeding
Punnett square
experiment
homozygous
having 2 identical alleles for a trait
heterozygous
having two different alleles for a trait
hybrid
an organism that has two different alleles for a trait
traits or characteristics that are the result of environmental factors cannot be
acquired trait
inherited
the deliberate modification of the characteristics of an organism by manipulating
genetic engineering
its genetic material.
