Define crossing over and explain when it occurs?
Crossing over allows daughter cells to be unique.1In genetics, traits that are usually linked, because they are caused by genes that are close together on the same chromosome, occasionally separate in offspring. This is called crossing-over, and is observed when geneticists are tracking traits in organisms.2In cytology, homologous chromosomes (e.g. the two copies of chromosome 7, or both copies of chromosome 12) can be seen to pair up during the first stage of meiosis (prophase I). The pair, which consists of two chromosomes and therefore a total of four chromatids, is called a bivalent. At a few points, typically three or four, along the bivalent, non-sister chromatids (i.e. one belonging to each of the two chromosomes), break and exchange segments. The place at which one of these breaks occurs is called a chiasma (plural chiasmata).The cytological event (the exchange of corresponding segments of DNA between non-sister chromatids of a homologous pair of chromosomes) explains the genetic observation.
What process helps make meiotic cells genetically different and occurs during prophase but not during prophase 2?
Th process of independent orientation of chromosomes while in their tetrad forms. But, the more important process that also happens in prophase I is the process of crossing over where chromosomes, male and female, exchange regions of the chromosomes, one with the other.
Gas exchange is also known as?
Respiration is a process of gas exchange. Respiration is necessary to supply cells with oxygen for metabolism and to remove the waste by product carbon dioxide.
Mitosis is the process of chromosome separation Cytoplasm is divided between the two daughter cells in a process known as?
Cytokinesis is the division of a eukaryotic cell into two daughter cells. This process usually begins in the late stages of mitosis and, sometimes, meiosis.
What process during meiosis causes genetic recombination?
Recombination may be caused by loci on different chromosomes that sort independently or by a physical crossing over between two loci on the same chromosome, with breakage and exchange of strands of homologous chromosomes paired in meiotic prophase I.
What is process in which homologous chromosome wrap around each and other exchange DNA?
crossing over
What is the difference between ventilation and gaseous exchange?
Gaseous exchange is a natural process, ventilation is a forced process.
Simplify meiosis into its basic events?
Homologous chromosomes pair up. Nonsister chromatids exchange segments in a process called crossing over. Because alleles etc.

How is the process of crossing over and independent assortment alike?
The crossing over is the process of exchange of DNA between homologous chromosomes whereas the independent assortment is the process in which the chromosome pairs align themeselves at the equator of the cell . Crossing over takes place in Prophase I of meiosis I whereas the independent assortment takes place in metaphase I of meiosis I.

What crosses over during crossing over?
Each chromatid can synapse with any one it want/chooses.
The process by which oxygen and carbon dioxide are exchanged between lungs and the environment is?
The Process of gas exchange is called Respiration
What is the process of separating chromosome called?
MItosis
