Answer: The newly found orchid species is Dioecious
Explanation:
Definitely, the new orchid species has female and male reproductive organs on the different plants (though of same species), thus the MALE wasps are attracted to it in order to aid POLLINATION by:
- transferring the already collected pollen grains collected from the anther of its male reproductive organs on another plant of the same species located in a different location.
Sex linked traits can only be held on the X chromosomes, so males only need one while females need two. Since the daughter has it, it must mean the mother is a carrier and has one normal X chromosome and another with the recessive trait (c).

Answer:
<h2>The cell will not pass the M checkpoint because its chromosomes will not associate with spindle fibers. or if the cell goes complete division, then the homologous chromosomes will go into either daughter cell.</h2>
Explanation:
As in the cell cycle, there are various checkpoints, which checks the cell in many steps like G1/S checkpoint, G2, M etc. They check the integrity of the genome, if there is any defect in the DNA/chromosome, it arrest the cell cycle.
Centromere is the region on the chromosome which binds with spindle fibers and is used in the separation of chromosomes during anaphase of cell cycle. If there is deletion of centromere, then the separation of chrmosome will be affected. Then the homologous chromosome can either go into one of the daughter cell, so one cell will get 2n+1 and other will get 2n-1.
Circumpolar. Circumpolar constellations are visible all year round. In the northern hemisphere, the famous circumpolar constellation is Ursa Major (The Big Dipper) which rotates around the North Star Polaris which always stays in the same place.
