|
The union of two haploid cells from two individual organisms.
|
Fertilization
|
|
How many sets of chromosomes do haploid cells have?
|
One set
|
|
How many sets of chromosomes do diploid cells have?
|
Two sets
|
|
The number of sets of chromosomes in a cell.
|
Ploidy level
|
|
Sexual reproduction includes a nuclear division that (increases/reduces) the number of chromosome sets.
|
Reduces
|
|
All the cells of a multicellular organism except the gametes or reproductive cells.
|
Somatic cell
|
|
Matched pairs containing the same genes in identical locations along their length.
|
Homologous chromosomes
|
|
These type of organisms inherit one copy of each homologous chromosome from each parent.
|
Diploid organisms
|
|
These type of organisms contain a single copy of each homologous chromosomes that are found only within structures that give rise to either gametes or spores.
|
Haploid cells
|
|
Haploid cells that can produce a haploid multicellular organism or can fuse with another spore to form a diploid cell.
|
Spores
|
|
A nuclear division process that results in four haploid cells.
|
Meiosis
|
|
The first round of meiotic cell division, referred to as reduction division because the ploidy level is reduced from diploid to haploid.
|
Meiosis I
|
|
The second round of meiotic cell division during which sister chromatids are separated into individual chromosomes, forming four unique haploid cells.
|
Meiosis II
|
|
Proteins that form a complex that seals sister chromatids together at their centomeres until anaphase II of meiosis.
|
Cohesion proteins
|
|
A protein lattice that forms between homologous chromosomes during prophase I, supporting crossover.
|
Synaptonemal Complex
|
