Basic Meiosis Terms
This term refers to the process by which a single cell divides to form four genetically distinct daughter cells.
What is meiosis?
This is the phase of meiosis where chromosomes (DNA) duplicate and form sister chromatids.
What is interphase?
The process in which chromosomes exchange segments during meiosis, increasing genetic variation.
What is crossing over?
The stage following meiosis (and mitosis) where the division of the cytoplasm occurs.
What is cytokinesis?
The name for the two divisions that occur during meiosis.
What are meiosis I and meiosis II?
In this phase of meiosis I, homologous chromosomes separate.
What is anaphase I?
This is the type of cell division that results in two identical daughter cells.
What is mitosis?
The stage during meiosis where the cell's chromosomes reduce from diploid to haploid.
What is meiosis I?
The type of cells produced by meiosis.
What are gametes (sperm and egg cells)?
This phase marks the end of meiosis I, where two daughter cells are formed.
What is telophase I?
The result of the random fusion of gametes from two parents.
What is fertilization
Sister chromatids are held together by this structure.
What is a centromere?
The term for the number of chromosomes in a gamete, which is half of the original cell.
What is the haploid number?
In meiosis II, this phase is where sister chromatids are separated.
What is anaphase II?
Meiosis reduces the chromosome number by half, while mitosis results in this type of cell.
What is a diploid cell?
This phase occurs only in meiosis, where homologous chromosomes pair up.
What is prophase I?
This is the type of cell division that results in 4 daughter cells.
What is meiosis?
During this phase of meiosis, chromosomes align at the equatorial plate for the second time.
What is metaphase II?
Matching chromosomes are called ____________ _______ .
What are homologous pairs?
In meiosis, this ensures genetic variation by shuffling alleles, while mitosis results in this kind of genetic outcome.
What is genetically unique (in meiosis) vs. genetically identical (in mitosis)?
