Organisms possess two types of genome viz; prokaryotic genome and eukaryotic genome. The eukaryotic genome is possessed by cells with a well-defined nucleus, where their genetic material (DNA). The prokaryotic genome, on the other hand, lacks a membrane-bound nucleus. The major organization or content between these two genomes are:

- Prokaryotic genomes generally have less DNA and fewer genes than eukaryotic genomes.

- Prokaryotic genomes have fewer repeated sequences and noncoding, intragenic sequences than eukaryotic genomes.

- Most prokaryotic genomes are contained in one circular chromosome while most eukaryotic genomes are contained on several linear chromosomes.

- In general, eukaryotic genomes contain many introns, repeated sequences, and transposable elements.

Based on this, all of the above options are TRUE

A man has blood type O, Rh negative. These are both recessive traits. He is married to a woman who has blood type A, Rh positive

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.
