Are mutations the only way to add new genes to a gene pool?
yes. independent assortment and crossing over in mitosis will add new combinations of alleles to the DNA but only mutations will create new genes.
Crossing over is an efficient way to produce?
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.
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.
Is re-assortment of a chromosomes can occur during meiosis by crossing over of non-sister chromatin's or by independent segregation of homologous chromosomes true or false?
true the assortment is called genetic recombination
What process produces genetic diversity through random distribution of chromosomes?
The random distribution of homologous chromosomes during meiosis is called independent assortment
Are mutations the only way to add new genes to a gene pool?
yes. independent assortment and crossing over in mitosis will add new combinations of alleles to the DNA but only mutations will create new genes.
How does meiosis introduce genetic variation into offspring?
1 by crossing over in prophase I , 2 by independent assoartment and 3 by mutations in s phase .1 by crossing over in prophase I , 2 by independent assoartment and 3 by mutations in s phase .Meiosis produces variation in gametes by crossing over & independent assortment also called reshuffling of genetic material . Such gametes after fertilization produce offspring with different characters .
Crossing over is an efficient way to produce?
independent assortment
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 are three ways to get genetic variation?
Independent assortment of chromosomes, crossing over and Random fetiliztion
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 causes continuous variation in humans?
There is variation among humans because of sexual reproduction, crossing over, assortment, and mutations.
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.
What is the genetic recombination of the kingdom animalia?
Meiosis, which includes crossing over and 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.
