Meiosis Phases
The phase in meiosis | where homologous chromosomes pair up and crossing-over occurs.
What is Prophase |?
The exchange of genetic material between homologous chromosomes during meiosis.
What is crossing over?
A reproduction process involving two parents combining genetic material.
What is sexual reproduction?
Cells that contain one set of chromosomes.
What are haploid cells?
The failure of chromosomes to separate properly during meiosis.
What is nondisjunction?
The stage where homologous chromosome pairs line up in the middle of the cell.
What is Metaphase |?
The process where chromosome pairs separate randomly, increasing variation.
What is independent assortment?
The cells that carry half the genetic information of an organism.
What are gametes?
Cells that contain two sets of chromosomes.
What are diploid cells?
A condition where cells have an abnormal number of chromosomes.
What is a chromosomal disorder?
The phase when homologous chromosomes separate and move to opposite poles.
What is Anaphase |?
The reason offspring are genetically different from their parents and each other.
What is genetic variation?
The fusion of sperm and egg cells.
What is fertilization?
The number of chromosomes in human body cells.
What is 46?
A syndrome caused by an extra X chromosome in males.
The stage where the cell divides into two haploid cells.
What is Telophase |?
The type of reproduction that increases genetic variation by combining genetic material from two parents.
What is sexual reproduction?
The cell formed after fertilization.
What is a zygote?
The number of chromosomes in gametes?
What is 23?
A condition where a female only has one X chromosome.
What is Turner syndrome?
How many times does a cell divide during meiosis?
What is two times?
The advantage of genetic variation for a species.
What is better survival in changing environment?
The early developmental stage that forms after the zygote divides.
What is an embryo?
The pairing of similar chromosomes, one from each parent, during meiosis.
What are homologous chromosomes?
The result of meiosis in terms of number and type of cells produced.
What are four haploid cells?
