Understanding Genetic Inheritance: A Two or Three Point Test Example

AI Thread Summary
A two or three-point test in genetics is primarily used for mapping linked genes. Participants in the discussion seek clarity on how to conduct these tests, emphasizing the importance of understanding parental genotypes and the results of single versus double crossovers. An example is provided with gamete frequencies to illustrate the process, encouraging individuals to engage with the material independently for a deeper understanding. The conversation highlights the significance of practical application in grasping genetic mapping concepts.

Hi everyone. Can someone please explain me how a two or three points test can be made, in the field of genetics? I've read of it in many books, but I'm looking for an explanation as clear as possible. Thanks in advance :)

I didn't understand your question
You want to conduct the 3 point test As in?
If I'm not wrong this 2-point 3-point test is to map linked genes right? Or are you referring to something else?
 
Correctly ...It's the test related to map the genes
 
Easier to do it with an example.[emoji4]
Try it out on your own first, you'll enjoy trying to figure it out on your own
Take this, simple-
The gametes
ABC-390
abc-374
AbC-27
aBc-30
abC-8
ABc-5
Abc-81
aBC-85

Firstly start off by identifying parental genotype and then which is the result of single cross and which double cross.

The study provides critical new insights into the African Humid Period, a time between 14,500 and 5,000 years ago when the Sahara desert was a green savanna, rich in water bodies that facilitated human habitation and the spread of pastoralism. Later aridification turned this region into the world's largest desert. Due to the extreme aridity of the region today, DNA preservation is poor, making this pioneering ancient DNA study all the more significant. Genomic analyses reveal that the...
Whenever these opiods are mentioned they usually mention that e.g. fentanyl is "50 times stronger than heroin" and "100 times stronger than morphine". Now it's nitazene which the public is told is everything from "much stronger than heroin" and "200 times stronger than fentany"! Do these numbers make sense at all? How do they arrive at them? Kill thousands of mice? En passant: nitazene have already been found in both Oxycontin pills and in street "heroin" here, so Naloxone is more...
