Answer: could you tell me the methods and its discription?
Answer:
6 in total; 3 viable and 3 non-viable
Explanation:
Robertsonian translocation is one of the types of structural alteration in chromosomes, in other words, a rearrangement between chromosomes, which can occur between five pairs of acrocentric chromosomes (chromosomes with the centromere close to the end of one of the "arms"): 13, 14, 15, 21 and 22.
An individual who has Robertson's translocation between chromosomes 14 and 21 generally has only 45 chromosomes.
In addition, a carrier of this type of translocation can theoretically produce 6 types of gametes, however 3 of them are not viable.
As for the three remaining gametes: One is normal, and among the other two, one is balanced and the last is unbalanced.
So, theoretically, when combining a normal gamete, the probability of a child with down syndrome being born through these conditions is 1/3 (considering that the probability of producing a certain type of gamete is equal for the three types).
Biotic:
Animals: animals are consider biotic because they are living things, they breath, walk, eat, sleep, reproduce, and drink water. and since biotic means living things, the animals are under the biotic category.
Plants: same as animals, but with plants they reproduce asexually meaning it requires only one organism to produce another life. Anything with cells in them are consider a living thing.
bacteria: same as plants and animals, they have cells so they are consider a living thing.
There are other types of biotic factors out there like producers, consumers and decomposes. Here are the ten things of biotic:
1. Bamboo plants (producers)
2. Banana Trees (producers)
3. orchids (producers)
4. Seaweeds (producers)
5. anteater (consumers)
6. Bears (consumers)
7.zooplankton (consumers)
8.bacteria (decomposers)
9. earthworms (decomposers)
10. termites (decomposers)
Those are the ten examples of biotic.
Abiotic:
Some of the examples include temperature, sunlight, soil, gases and atmospheric, these are consider the non-living things but here are 5 examples of abiotic factors in the ecosystem.
1. Altitude
2.pollution
3.soil
4.wind
5. Ph
Hope this helped :)
Have a great day
Answer:
ATG
Explanation:
T (thymine) pairs with the base A (adenine) and C (cytosine) pairs with the base G (guanine)
The examination above is called Cohort Observational Study. The cohort study is a sort of restorative research used to explore the reasons for the malady, building up joins between chance variables and wellbeing results. Partner ponders are as a rule forward-looking - that is, they are "forthcoming" studies, or arranged ahead of time and did over a future timeframe
