Depending on what trait the alleles carry, the brothers will have a different phenotype and a different genotype.
For example; Eye color. My sister is heterozygous, meaning she has brown eyes. I am homozygous recessive, meaning I have blue(green/hazel) eyes. We both have the same parents, I just happened to inherit both of the recessive eye color alleles from my parents whereas, my sister inherited both the dominant and recessive alleles.
So, since the brothers inherited different sets of alleles, their genotype for a certain trait will be different.
Answer:
Here are some. I discovered that the clean and unclean food and hygiene laws found in the Book of Leviticus have been based all this time on the God of Abraham's working knowledge of the germ theory of disease and the modern human body and other advanced fields of science unknown to mankind at that time and some fields of science still unknown to mankind today. These laws and instructions still apply to modern times for all humans to follow to help keep our bodies healthy and disease free until we grow old and die of old age.

<span>Base on a study that was undertaken in order to compare the
respiratory responses of hypnotized and non-hypnotized subjects to certain
instructions. According to a study, the 16 male volunteers were allocated to a
random experimental group to be hypnotized or to a control group. Baseline
measurements were taken at the start of the experiment. Analyzing the data,
researchers noticed that the baseline breathing patterns of the two groups were
different; One explanation proposed for this unexpected experimental the
difference of the group was more excited in the anticipation of the experience
in being hypnotized.</span>
I think it's the cuticle and the upper epidermis.
