If a mother is blood type O and a father is heterozygous for a blood type B, their children's blood types can be A- B or O only
B- A, B, or O only
C-A or B only
D- A, B,O, or AB only

A- B or O only, because there's no type A in the parents so the kid couldn't possibly have a blood type A.

hope this helps!!!

volcanoes (an event in the geosphere) release a large amount of particulate matter into the atmosphere. these particles serve as nuclei for the formation of water droplets (hydrosphere). rainfall (hydrosphere) often increases following an eruption, stimulating plant growth (biosphere).

small, big, or no change could occur in the phenotype. it could cause something as simple as a cats ears to curl backwards or something as frighting as death. it could also occur in the protien-coding area and have an effect on that but no effect on the amino acids. what has to occur is a changing in the hox gene or the control gene.
