IAIARr is the genotype of the mother.
<h3><u>Explanation</u>:</h3>
The blood groups are the heredity characteristics of the individual which governs what antigen will be present in blood and what antibody will be present in the blood plasma.
The blood group has the genetic characteristics where A and B are dominant characters and O is the recessive character. Co Dominance is seen in case of blood grouping. Similar characteristics is seen with Rh character too where Rh positive is the dominant character and Rh negative is recessive.
The father has both the recessive characteristics. So he needs to be genetically homozygous which means that he has genetic setup of IoIo and rr.
Two child born has character of A blood group and rh positive, but the other child is A blood grouped and rh negative.
So the mother ought to be heterozygous with respect to Rh group, but she is homozygous with respect to blood group.
So her genetic setup is IAIARr.
Answer:
nonsense mutation
Explanation:
In DNA, the uracil (U) is replaced by thymine (T). If a change in the DNA sequence, or mutation, of a gene occurs that creates a stop codon, this is called a nonsense mutation.

Answer:
In three domain system Eukarya includes organisms from more than one kingdom
Explanation:
Of the biological taxonomy, domain is one of the rankings that keeps living beings organized. It is the highest ranking of taxonomy. Eukarya is the domain that contains organisms that are eukaryotic. These organisms has cells that has membrane bound organelles and a nucleus in it.
This domain includes more than three kingdoms. These domains are- Animalia, Fungi, Plantae and Protists. The organelles that belonged to this domain are called Eukaryotes.
The media plays a very important role as a source of information,education and entertainment, whether it is radio, movies or TV. It accommodates the world in to a single village which is saturated of media-information, that cause us to wear what we do, drink what we drink and eat what we eat.
