According to mendel's law of assortment, the phenotypic ratios between them should be 9:3:3:1, it's a dihybrid cross and Law of Independent Assortment. The law states that "each allele pair segregates independently during gamete formation" It's given by mendel who's also known as "father of genetics"
Traits are determined by the genes. Genes have segments known as DNA and RNA. An allele is an alternative version of gene expression inherited. We find out about f1 and f2 generation.

Answer:
Magnetic renosance imaging (MRI) scan
Explanation:
Magnetic renosance imaging scan uses large magnets, radio waves and computer to produce well detailed image of the body.
An MRI scan usually about 15-90 minutes depending on the size of the body being scanned and how many images is needed. So for the doctors to get a detailed 3 dimensional structure of Milo brain structure, the technique to be used is the MRI scan.
