The probability that their son exhibits the 'color blind' trait is 0%. It is a type of inheritance linked to the X chromosome.

<h3>Inheritance linked to the X chromosome</h3>

In men, the patterns of inheritance linked to the X chromosome don't follow conventional mendelian inheritance because men have only one X chromosome.

Conversely, women have two X chromosomes, thereby the inheritance pattern resembles Mendelian inheritance.

It is important to highlight that color blindness is a recessive trait on the X chromosome.

In this case, the mother is a carrier, thereby the probability of passing this trait as a carrier to her son is 50%, whereas the father is normal, thereby the probability of passing this trait to his son is 0%.

sasho [114]

Dominance is not inherent to either an allele or its phenotype. It is a relationship between two alleles of a gene and their associated phenotypes; one allele can be dominant over a second allele, recessive to a third allele, and codominant to a fourth.

Insulin is made by pancreatic cells, packaged in small vesicles, and then released into the bloodstream. this describes what sor
aksik [14]

According to the research, the correct option is exocytosis. Insulin is made by pancreatic cells, packaged in small vesicles, and then released into the bloodstream. This describes <u>exocytosis</u> cell transport.

What is exocytosis?

It is the expulsion, by cells, of particles that, due to their size, cannot pass through the cell membrane.

In this sense, it is the process by which different types of molecules contained in a cytoplasmic vesicle of a cell are secreted. Insulin is released to the outside by exocytosis, intervening in the process of glucose entry into cells.

Therefore, we can conclude that according to the research, the correct option is exocytosis. Insulin is made by pancreatic cells, packaged in small vesicles, and then released into the bloodstream. This describes <u>exocytosis</u> cell transport.
