Explanation:

The X chromosome is the female sex chromosome and when you have a pair of X chromosomes (XX), then that would denote that the subject is female. Now when it comes to x-linked traits, for a female to be affected, she would have to have the allele on both chromosomes, or in this case, homozgous for color-blindness. (If it is found only on one, she would be a carrier, but she won't be affected.)

So the answer would be: XᵇXᵇ

amber has allowed scientists to study dna that has been preserved over millions of years.

the nitrogen cycle provides nitrogen to the ecosystem from the atmosphere, ground and oceans. nitrogen is an important component of complex molecules such as amino acids and nucleotides, which lead to the creation of proteins and dna, the building blocks of all life. plants absorb nitrogen in the form of ammonium, nitrate ion and, on rare occasions, as amino acids. animals receive nitrogen necessary for biological processes from feeding on living or dead organic matter.
