Biology
How many times does a cell replicate during mitosis
1
How many times does chromosome separation occur in meiosis
2
Haploid
A cell with one of each kind of chromosome
Diploid
A cell with two of each kind of chromosome
Homologous
A pair of chromosomes that contains similar genetic information
Tetrads
A pair of homologous lined up side by side during prophase 1 of meiosis
Crossing over
An exchange of Dan between two homologous
Which phase does homologous chromosomes seperate and move to opposite ends
Anaphase 1
What is common in mitosis and meiosis
Anaphase in mitosis and anaphase 2 in meiosis, sister chromatids Go to opposite ends
Haploid
Cells produced by mieosis
Somatic cells
Cells that contain a diploid number of chromosome
Sex cells
Cells that contain a haploid number of chromosome
Homologous
Chromosomes have genes for the same trait in the same order on both chromosomes
What is division of the entire cell called
Cytokinesis
When male and female gametes units
Fertilization
Study of heridity
Genetics
Haploid
Having half of the usual number of chromosomes
Nondisjunction
Homologous chromosomes not separating properly
What is the longest part of the cell cycle
Interphase
What phase does the cell replicate it's chromosome
Interphase
What phase does homologous chromosomes line up at the equator in Paris
Metaphase 1
What is division of the nucleus called
Mitosis
Heredity
Passing in if traits to offspring
In what type of cell does Meiosis occur
Reproductive cells
Gametes
Sperm of egg cell
Autosomes
The chromosomes that do not determine gender
Sex chromosomes
The pair of chromosomes that determines gender
Mitosis
The process that produces diploid cells
Meiosis
The process that produces haploid cells
Genetic recombination
The reassortment of genetic information
Crossing over
When non sister chromatids exchange genes
