Pass It On!
The basic unit of heredity.
What is a gene?
The number of cell divisions in meiosis.
What is two?
The source of new alleles.
What is random mutation?
This combination of genes are usually inherited together and are located near one another on the same chromosome.
What are linked genes?
Meselson and Stahl cultured E coli bacteria to prove that DNA replication follows this model.
What is semi-conservative?
The cell that forms when two haploid cells join in fertilization.
What is a zygote?
The chromosome number of daughter cells at the end of meiosis II.
What is n?
Two types of allele combinations.
What are homozygous and heterozygous?
Thomas Hunt Morgan experimented with this organism to conclude that chromosomes are the basis of inheritance.
What is the fruit fly (Drosophilia melanogaster).
This shows the relative location of genes along a chromosome.
What is a linkage map?
An ordered display of chromosome pairs.
What is a karyotype?
In plant cell cycokinesis, vesicles from this organelle move to the center and form a new cell plate, which becomes the structural basis for the new cell wall.
What is the Golgi complex?
The type of dominance seen when a red-flowering plant crossed with a white-flowering plant produces plant with pink flowers.
What is incomplete dominance?
This is the phenotype most commonly observed in the natural population.
What is the wild type?
A nucleotide-pair substitution of one amino acid for another.
What is a missense mutation?
Plants and some algae follow this type of life cycle, having both diploid and haploid phases.
What is alternation of generations?
In anaphase I, these structures separate.
What are homologous pairs?
These three processes contribute to the genetic variation seen in sexual reproduction.
What are independent assortment, crossing over, and random fertilization?
This test can be used to determine the probability that two genes are linked.
What is the Chi square test?
A structural alteration in human chromosomes where a gene is moved from one chromosome to another during mitosis.
What is translocation?
Venki Ramakrishnan, who won the 2009 Nobel Prize in chemistry, has said that this organelle is "the interface between genotype and phenotype."
What is the ribosome?
In prophase I, genetic information is exchanged between these structures.
What are non-sister chromatids?
The circumstance where genes have multiple phenotypic effects.
What is pleiotropy?
What are extranuclear genes OR cytoplasmic genes OR mitochondria, chloroplasts, and plastids?
What is nondisjunction?
