Reproduction
This type of reproduction involves only one parent and produces genetically identical offspring.
What is asexual reproduction?
Humans have this many total chromosomes in somatic cells.
What is 46?
The stage of meiosis where homologous chromosomes line up at the equatorial plate.
What is metaphase I?
The exchange of DNA between homologous chromosomes during meiosis.
What is crossing over?
The phase where DNA is replicated.
What is S phase?
This type of reproduction produces genetically diverse offspring through fusion of gametes.
What is sexual reproduction?
Chromosome pairs that contain the same genes but may have different alleles.
What are homologous chromosomes?
The stage of meiosis when homologous chromosomes separate.
What is anaphase I?
The random orientation of homologous chromosomes during metaphase I.
What is independent assortment?
The longest phase of the cell cycle that includes G1, S, and G2.
What is interphase?
The reproductive cells that carry genes to the next generation.
What are gametes?
Identical copies of a duplicated chromosome joined at the centromere.
What are sister chromatids?
The stage where crossing-over occurs.
What is prophase I?
These structures form where crossing over occurs.
What are chiasmata?
The stage of mitosis where chromosomes line up in the middle of the cell.
What is metaphase?
The process that produces haploid gametes from diploid cells.
What is meiosis?
The structure that holds sister chromatids together.
What is the centromere?
The result of meiosis — this many daughter cells are produced.
What is four?
The number of possible chromosome combinations in gametes is calculated using this expression.
What is 2ⁿ?
The division of the cytoplasm after nuclear division.
What is cytokinesis?
The cell formed when sperm and egg fuse together.
What is a zygote?
The complete set of chromosomes in a cell.
What is the genome?
ells produced by meiosis have this number of chromosome sets.
What is haploid (n)?
The process that maintains chromosome number across generations through meiosis and fertilization.
What is the sexual life cycle?
The checkpoint considered the most important control point in the cell cycle.
What is the G1 checkpoint?
