The surviving children would be 66.7% female and 33.3% male. Of the female children, 50% would be expected to be carriers of this gene (like their mother)
| Xg | X

X | XXg | XX

Y | XgY | XY
Pretty ugly, but the best punnet square I can do without a link. The offspring with the “g” are those that carry the lethal gene. The male child that carries it will die, but since it is recessive, the female child will live but will be a carrier for this gene. I hope this helps.
A haploid cell has half the total number of chromosomes, so the animal, which has mostly diploid cells, would have 16 chromosomes.
Hydra and Obelia are cnidarians (species of aquatic organisms) that belongs to the Class Hydrozoa.
Several ways in which Obelia differs from Hydra are;
- Hydra is a predative species that lives on substrates such as wood, while Obelia is a colonial species that lives as polyps on branched frameworks.
- Hydra is found in freshwater habitats, while Obelia is found in marine habitats.
- Hydra undergoes the medusa form in its life cycle, while Obelia undergoes the two forms (polyp and medusa) in its life cycle.
- Hydra has great regenerative powers while Obelia does not have great regenerative powers.
Answer:
A transform plate boundary
These are all forms of movements, but by definition, if they slide past each other, it's transform!
