You can't have a carrier with a dominant pedigree because other wise than individual or organism would be afflicted by the gene and render them incapable of being a carrier. A carrier is an individual/organism that has a normal phenotype (meaning it is not afflicted by said gene) but is carrying the gene that could cause disease or whatever the affect may be. In this case the gene would have to be homozygous recessive to be expressed. Hopefully this helps!
Buildup of organisms means that the species number is pretty high.
Gradual change means that it was a slow, calm time to make the change.
I hope this helps!!
If
you check the barometric pressure and find that [sic] it is reading
only 920 millibars ... two effects possibly responsible for this lower
than average reading are 1) elevation (~2500' MSL) or 2) a LOW
pressure weather system such as a mid-latitude or tropical cyclone. Also <span>A storm is approaching or barometer is read over a mountain</span>
