Two brothers have X‑linked red–green colorblind vision, and their parents have normal color vision. The first brother's karyotyp
zhenek [66]

Answer:

The answer is mother in meiosis II

Explanation:

nondisjunction can be defined as the failure of the segregation of the child chromosomes in meiosis I and meiosis II resulting in gametogenes. This results in abnormal gametes with some chromosomal imbalance being formed and subsequent fertilization of these gametes results in a generation of abnormal individuals.

According to exercise, red-green color blindness follows an X-linked recessive pattern and the phenotype is only expressed. the father cannot bring the possibility of color blindness to his children, and the nondisjunction, defined earlier, cannot occur in either meiosis I or meiosis II. As a conclusion we can say that it may have a place in meiosis I or meiosis II corresponding to the mother and although the mother's condition may be normal, the first child would be compromised with color blindness, therefore, the mother is the carrier.

Which fields can NMR technology be applied? Any help would be appreciated. Thanks in advance!
prohojiy [21]

Answer:

Nuclear magnetic resonance (NMR) technology can penetrate materials without destroying samples, and has the advantages of fast, accurate and high resolution. As a means of studying material properties, it has been widely used in the fields of environment, medical imaging, material structure identification, biochemical analysis, food analysis, coal chemistry, soil science and so on. In the field of soil science, the carbon in soil organic matter samples from forest surface was analyzed by solid NMR technology Dignac, etc. With the help of various experimental techniques, the functional relationship between carbon-nitrogen ratio and element content was obtained, and the change rule of carbon-nitrogen content was confirmed in specific areas. In medical imaging, image formation is the spatial distribution of longitudinal relaxation time and transverse relaxation time and the display of nuclear density reflected by NMR signals. In the field of polymer materials, NMR technology can be used to study the adsorption, desorption and diffusion of polymers in solvents containing different particles. In the field of environment, nuclear magnetic resonance (NMR) has shown its unique importance in studying water uptake in soil and soil wettability.
