Crossing over is the exchange of genetic material between chromatids. This is also known as synapsis, and it occurs during prophase one of meiosis.

Explain the exchange of chromosome segments between chromatids of homologous or non-homologous chromosomes?
a. crossing over b. independent assortment or c. random fertilization
Cells in a cell culture all have the same genetic material because they are A. vectors B. plasmids C. hybrids D. clones?
Cells in a cell culture of similar genetic material are called clones. vectors can be the carriers of viruses . Plasmids are the extrachromosomal genetic material. Hybrids are the cells produced from the combination of two cells.
A is not a living thing it is made of genetic material inside a protein coat?
Virus
Where do you expect genetic differences between cells to arise from mitosis or from meiosis?
That is a good question. In mitosis, you don't get regular genetic variation but chance mutations can occur. In meiosis with fertilization, you get pairing of DNA from different hosts on a regular basis. I would choose the latter.
Which type of reproduction results in the greatest amount of genetic variation?
That would be sexual reproduction. Sexual reproduction allows for independent assortment and crossing over to occur. This is fancy language for the genetic material gets mixed up a lot. Since the genetic material gets mixed up, variation will result.
Crossing over involves the exchange of genetic information between what?
Non sister chromatids
Which part of chromosome exchange during meiosis centromere or telomere?
During meiosis, chromosome exchange occurs at the chiasmata, which are points of crossing over between non-sister chromatids. The exchange involves the exchange of genetic material between homologous chromosomes, not specifically at the centromere or telomere regions.
When occurs between nonsister chromatids genetic exchange between chromosomes provides new combinations of genes that are different from the parent cell?
crossing over
What trem describes the exchange of genetic material between members of a homologous pair of chromosomes?
Crossing over during meiosis results in to exchange of genetic material between members of a homologous pair of chromosomes.
Do sister chromatids have half the amount of genetic material as the original?
yes they do
What is the term for the exchange of genetic material between bacteria via contact between individuals?
the word is conjugation
What occurs when chromatids exchange some DNA and this results in genetic variety?
crossing-over occurs and random fertilization
Prior to cell division each chromosome replicates it genetic material The products are connected by a centromere and are called?
Sister chromatids
Reproduction that occurs with an exchange of genetic material is?
sexual
Genetic mixing of genes that result from crossing-over?
Recombination is the genetic mixing of genes that result from crossing over.
What is a plasmid exchange?
Plasmid Exchange is the transfer of genetic material between bacteria through direct cell to cell contact, or through a bridge-like connection between the two cells.
What is sexual reproduction where there is an exchange of genetic material?
by a asexuall reproduction
