Humans only have a few eye colors and only four abo-based blood types. how can dna tests definitively identify individuals when many people have brown eyes or type a blood?

DNA testing utilized particular regions in our DNA that are unique to every individual. These regoins are tested using tehcnques such as RFLPs (Random Fragments Length polymorphisms),  SNP (Single Nucleotide Polymorphism), STR (Short Tandem Repeats), Y chromosome (for males) and mitochondria DNA analysis (for females).

i'm gonna put a couple so you can chose from

explanation:

if you know the fur color of the offspring mice, you can use the ratios to identify the genotypes of the parents.

if either parent mouse passes a dominant allele, the offspring will have black fur.

if the parental mice has two different fur color (i.e white and black) , the color of the offspring's fur would be either black, white, or the combination of both (grey)

hope this : )

acceleration= v2-v1/t so 8m/s-3m/s / 3s =to 8/3 or

2.67 m/s^2

hope i
