Flashcards in Meiosis 9 Deck (26):
Develops a form of zygote.
How many body cells do humans have.
2 set of chromosomes
1 set of chromosomes
The process of meiosis produce gametes with ________ as body cells
1/2 the number of chromosomes (23 from each parent)
Requires 2 parents and increases genetic diversity.
Specialized cells; sperm from males and eggs from females.
Variety in species.
New diploid cell formed by the process of fertilization.
Starts with a diploid cell and ends with 2 haploid cells
Starts with a diploid cell and ends with 4 haploid cells.
Same as everything in mitosis
Process in which from two parents combine.
Chromosomes begins to condense and pair up. Align with their homologous partner so they match up.
Daughter cells only have 1 copy of each homologous chromosome
No synapsis/crossing over.
Sister chromatids line up across the middle of the cell and is completely random.
Pulled to the end of the cell.
Cytoplasm is reformed
(2 cells one cytoplasm)
Separation of 2 cells resulting in 4 unique haploid cells.
G1: Growth and preparation
S: DNA replication
G2: Grows more and prepares for mitosis
Replicated DNA coil into x-shape chromosomes
Spindle fibres attach to centromere
Spindle fibres pull the chromosomes into a single line.
Spindle fibres contract and pull centromere apart separating sister chromatids.
