Genetic engineering involves the use of recombinant DNA technology, the process by which a DNA sequence is manipulated in vitro, thus creating recombinant DNA molecules that have new combinations of genetic material

What process provides the genetic variability that natural selection acts on during evolution?
The ultimate source of variation is mutation. However, recombination, or crossing over, can produce enormous amounts of variation by shuffling alleles into different combinations. Combined, the two processes produce the variation upon which natural selection can act, and which results in evolution.
An advantage of sexual reproduction is?
An advantage of a sexual reproduction is that it is able to produce more offspring because of the mate. Children are different from the parents and more genetic variation species.
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 .
Why cross pollination produces more genetic variation in the offspring than self pollination produces?
Cross-pollination produces more genetic variation in offspring because it is a different set of DNA that is breeding with the parents DNA to produce the offspring (known as sexual reproduction). In asexual reproduction, the parent plant uses a clone DNA to self pollinate thus creating an exact copy of the parent. Asexual reproduction inhibits genetic variation because the offspring will never develop mutations that could help natural selection.
How does most bacteria reproduce?
*** they do, through a process called conjugation. which is where bacteria join and share and exchange genetic materials. once the genetic materials are exchanged, each baterial cell will go through binary fission to produce an offspring with a new genetic makeup.
Ability of bacteria to produce insulin was result of?
Genetic engineering of the bacteria.
How does natural selection produce genetic variation within a species?
It's mainly mutations in the DNA and recombination of chromosomes that produce the genetic variation. Natural selection then favors those changes that give rise to greater reproductive success.
Crossing over and the separation of duplicated homologous chromosomes in the first division produce genetic variation?
true
Tetracycline is used in genetic engineerin experiments as a way to?
Produce stronger strains of bacteria
How could people use the genetic variation in wild roses to create roses that produce large flowers?
cross breed them
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.
In regards to taxonomic classification of bacteria what is the relationship between physiological and genetic differentiation of bacteria?
You're lame typing the answer as exactly as it is on the lab manual......I.V. Genetic differences between bacteria causes specific physiological differences among the bacteria, such as certain morphological characteristics as well as what compounds the bacteria can ferment and produce as by-products in this process.
Which description does not apply equally well to both sexual and asexual spores?
The ability to undergo meiosis and produce genetic variation does not apply equally well to both sexual and asexual spores. Sexual spores are formed through meiosis, which shuffles genetic material and leads to genetic variation. Asexual spores, on the other hand, are produced by mitosis and do not contribute to genetic diversity.
Four examples of genetic engineering?
Genetic engineering can be done with animals, produce and bacteria. Organisms that undergo genetic engineering are called genetically modified organisms. Some of the earliest GMOs were bacteria and mice. Food products, glofish and zebra fish are some of the more recent GMOs.

An advantage of a sexual reproduction is that it is able to produce more offspring because of the mate. Children are different from the parents and more genetic variation species.
What Transgenic bacteria can be used to produce?
Genetically modified bacteria can be used to produce. This is a transgenic bacteria.
