Crossing over is the event in which non-sister chromatids of homologous chromosomes swap or exchange DNA segments. This produces new gene combinations and only occurs in prophase 1 when tetrads form. independent assortment is the random orientation of pairs of homologous chromosomes at metaphase 1

Crossing over is an efficient way to produce?
independent assortment
Describe two ways in which genetic recombination occurs during meiosis?
The independent orientation of chromosome tetrads in prophase I. Simplified diagram, FM FM or FM MF Crossing over also in prophase I. A part of the female chromosome and a part of the male chromosome, aligned together, swap places; genetic material.
Compare the process of crossing-over and independent assortment?
Crossing over is the exchange of DNA between homologous chromosomes where as Independent assortment is the process in which the chromosomes pair align themselves at the equator of the cell.
What is the mechanism for the production of genetic recombinants?
Crossing over and independent assortment
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 is the genetic recombination of the kingdom animalia?
Meiosis, which includes crossing over and independent assortment
What process produces genetic diversity through random distribution of chromosomes?
The random distribution of homologous chromosomes during meiosis is called independent assortment
In what two ways does meiosis provide genetic variation?
The two sources of genetic variation in a cell during Meiosis are crossing-over during synapse and independent assortment.
The calculation of offspring includes only variation resulting from?
crossing over, random fertilization, and an independent assortment of chromosomes
Explain the exchange of chromosome segments between chromatids of homologous or non-homologous chromosomes?
a. crossing over b. independent assortment or c. random fertilization
What are the steps of meiosis directly responsible for some of the genetic variation seen in a given population?
Independent assortment, crossing over.
What are two main sources of genetic?
Crossing over of choromosomes and Mutation in cells. The law of independent assortment help as well.
