Answer:
I^A,I^B,and I
Explanation:
The I^A and I^B alleles are co-dominant, and the I allele is recessive.
We label the human sex chromosomes with X's and Y's. For example. A boy's chromosomes are XY. A girls chromosomes are XX. When a child is born, they get an X from their mother, and either an X or Y from their Father, thus determining their sex.
The correct statement is that "Archaea are older organisms than eukaryotes"
- Archaeans are group of organisms classified under the domain Archaebacteria. They are found in environments with extreme conditions e.g. high temperature etc.
- They are prokaryotic in nature i.e. they do not possess a membrane-bound nucleus in their cells.
- Based on this, archaea are not classified under the same domain as bacteria (domain- protista). They are unicellular organisms.
- However, archaea are older set of organisms than eukaryotes. This is the correct statement among the options provided.

Answer:
Meiosis is important because during sexual reproduction, it ensures that all produced organisms have the correct number of chromosomes. It is also responsible for producing genetic variations during the process of recombination, and it repairs some genetic defects.
The disadvantage from not having the trait normally arises only after the reproductive stage of the individual's lifecycle is mostly over. This is a special case of "no strong pressure", because evolution selects genes, not the organism. In other words the beneficial mutation does not alter the reproductive fitness.
