Answer: For decreased chances of rejection

Explanation:

The three higly polymorphic MHC 1 genes in human beings are HLA-A, HLA-B and HLA-C.

These determine the compatibility of the organ or tissue in the recipient's body each by the help of many alleles that segregates in a population.

There are very less chances that a random chosen donor will match the a recipient six allele genotype.

This is the reason parent  may be the best donor for organ transplantation or tissue transplantation.

Answer:

i would like to choose sublimation process to explain about water cycle.As mentioned, sublimation is the process in which snow melts and water get vaporized. Ice melts and turns into water which flows to the seas and oceans.When the temperature increases during the day time, water gets vaporized.Water vapour begin to move upward.As we know, temperature decreases with the increase in height.Due to which water vapour rises,cools and then changes into tiny water molecules.Those water molecules forms cloud.Then the clouds get heavier and begin to collide with each other.As a result rain fall occurs.

Evapotranspiration has also the same process but the difference is that it involves vaporization of water from some biological factor like plants and physical factor like from soil .

i think its my first longest answer which i answered here.Thank you for the amaizing question. Its simple but most important topic

Explain how you determined the genotype of Maria and Juanita, even though you did not test their DNA.
polet [3.4K]
The answer is a pedigree chart.

<span>Pedigree charts are used to explain the occurrence of particular genes from one generation to the next. It gives enough information about family disease history. They are used in families to find out the probability of inheriting some disease. So, if Maria and Juanita are cousins and the genotypes of other members of their family are known, the pedigree chart could predict their genotypes. Still, it is not as precisely as DNA test.</span>
