Answer:
organelles are very similar to present-day bacteria, suggesting a common ancestor.
Explanation:
Some evidence suggests that some organelles like mitochondria and chloroplasts within eukaryotes were once used to be independent eukaryotes.
Endosymbiosis theory says that ancestral prokaryotic cells engulfed bacteria like cyanobacteria which with time evolved into mitochondria and chloroplast. Molecular evidence also proves that these organelles were once prokaryotic organisms because they show similar genetic makeup and ribosome type.
So these organelles are similar to present-day bacteria showing that they have a common ancestor.
Hello!! I always remember recessive genes as someone having a passive personality and dominant genes as having an assertive personality. Therefore, dominant genes would mask others when present because they have that assertive personality. If you think about it as babies, when their dad has darker hair and the mother has lighter hair, the baby will most likely have darker hair because the darker hair is the dominant gene. I would say that the answer would be false. If you are having trouble understanding, you can always make a Punnett square and see what your outcomes are. I hope I helped. Have a great day!!
