Karyotyping is used to:
study chromosomes.
treat Down syndrome.
repair chromosomes.
diagnose genetic diseases.
Answer:
True
Explanation:
The linkage relation of two genes can be determined on the basis of calculating recombination frequency.
If the recombination frequency value is greater than 50% then the genes are not linked and if the value is less than 50% then the genes are linked.
In the given question, the crossover gametes formed will be Ab = 100
and aB= 106.
Therefore,
Since the recombinant frequency value is larger than 50% therefore the genes do not show linkage.
Thus, True is the correct answer.
The greenhouse gases effect the environment by leading to climate change and global warming.
Due to green house gases the earth become warmer than normal.This affect weather patterns which led to global warming and climate change.In the last 3 million years the amount of greenhouse gases in our atmosphere is the highest which led to global warming.
