What are all the possible sources of genetic variation in sexuaally repdoucing organisms?

Biology
1 answer:
Allushta [10]3 years ago
7 0

Answer:

Mutation, Gene flow/Migration/Immigration of gene and Recombination

Explanation:

For any species there are majorly three sources of genetic variations –  

a) Mutation – This leads to change in the genetic code with in the DNA of an organism. Sometimes mutation does not produce any effect on the organism. Mutation can produce both positive and negative impact. Its effect is observed in long run as its rate is slow.

b) Recombination – When an organism undergoes sex, his/her genes recombine with the genes of mating partner. The rate of recombination is faster than the rate of mutation  

c) Gene flow /Migration/Immigration of gene – In this gene travel from one set of population to the other. The frequency of gene in the mixed population lies between the original population gene frequency and the migrated or donor population gene frequency

What is the best way to prevent information from being lost when working on an important document?
Ivenika [448]
We should save the document regularly when working on the document. If the app breaks down, you'll still have the file with your progress. To be extra safe, save the document in multiple places including the computer itself, also your USB drive. just so in case if the computer breaks down, you still have your USB drive.

What is "static pressure" in Hearing Science? <br><br> I will mark brainliest!
djverab [1.8K]

Answer:

It has long been known that static pressure affects middle-ear function and conventional tympanometry uses variations in static pressure for clinical assessment of the middle ear. Middle-ear under-pressures tend to reduce the velocity magnitude more than do middle-ear over pressures.

The effect of middle-ear static pressure on the acoustic response of both structures is similar in that non-zero middle-ear static pressures generally reduce the velocity magnitude of the two membrane components in response to sound stimuli.

Who is good at biology and that can help me??????
Aleks [24]
It is kind of difficult for me even, but I know that neutral objects<span> have an even amount of opposite </span>charges<span>. When </span>brought near a charged object<span> the </span>neutral's<span> protons will lean toward excess electrons on the </span>charged<span> one. A positively </span>charged object<span> will attract the neutrals electrons to move toward it. I hope that kind of helped. Sorry if I couldn't give a direct answer! Its kind of hard for me too and I'm an A+ student in bio</span>

Different cell types can react differently to epinephrine in the human body. Choose two cell types in the human body and briefly
Ipatiy [6.2K]

Answer:

I haven't really learned about cell types but I did find this information

Explanation:

How can epinephrine have different effects on different cells? Different cells have different receptors that bind epinephrine. Different cells activate different enzymes as a result of epinephrine binding.

epinephrine induces increased vascular smooth muscle contraction, pupillary dilator muscle contraction, and intestinal sphincter muscle contraction. Other significant effects include increased heart rate, myocardial contractility, and renin release

Hope it at least helps a little :)

What is the role of camouflage in prey and predator
Luba_88 [7]

Answer:Camouflage, also called cryptic coloration, is a defense or tactic that organisms use to disguise their appearance, usually to blend in with their surroundings. Organisms use camouflage to mask their location, identity, and movement. This allows prey to avoid predators, and for predators to sneak up on prey.
