Making a genetically identical copy of DNA or of an organism.
What is Cloning?
the passage of genetic information from parents to offspring
What is Heredity?
a diagram that shows the potential combinations of genotypes that occur in offspring of the cross between two parents
What is a Punnett Square?
One of two or more forms that a gene could take
What is an Allele?
Austrian monk and botanist whose experiments in breeding garden peas led to science of genetics
Who is Gregor Mendel?
Developed the double helix model of DNA.
Who are Watson and Crick?
a characteristic of an organism
What is a Trait?
having two alleles that are different for a trait
What is heterozygous?
the offspring of organisms that have the same traits
What is Purebred?
an allele that is always expressed when it is present
what is dominant?
The process in which DNA makes a duplicate copy of itself.
What is DNA replication?
a section of chromosomes that determines or helps to determine a trait or characteristics that will appear in an organism
What is a Gene?
having two alleles that are the same for a trait
What is homozygous?
Both alleles for a trait are the same and recessive
What is homozygous recessive?
The scientific study of heredity
What is Genetics?
sugar found in DNA
What is Deoxyribose?
Long strands of DNA inherited from parents found in the nucleus. You get 23 from each parent.
What are Chromosomes?
The predicted number of offspring that show the dominant phenotype when one parent is homozygous dominant.
What is 4/4 or 100%?
the offspring of genetically different parents
What is Hybrid?
an allele that is not expressed or shown when the dominant allele is also present.
What is a Recessive Allele?
A building block of DNA, consisting of a sugar bonded to a nitrogen base and a phosphate.
What is Nucleotide?
Symbols representing the different generations in a genetic cross.
What are P1, P2, F1, F2?
The predicted number offspring that have the recessive phenotype when both parents are heterozygous
What is 1/4 or 25%?
a random error in gene replication that leads to a change
What is a mutation?
the physical appearance of an organism or which version of a trait is visible
what is phenotype?
