Ответ:

2(A0)и 3(B0)

Объяснение:

Так как 1 группа крови 00, а 4 AB мы может сделать вывод, что оба родителя гетерозиготны по признаку группы крови, т.к если бы, например у матери была 2 группа крови АА, то не мог бы родиться сын с 1 группой крови.

Killer quakes rattle Japan
Powerful earthquakes jolted central and eastern Japan Saturday evening, killing 18 person in Niigata Prefecture, injuring about 900 others, destroying a number of buildings and causing a bullet train to derail, government and police officials said.
The initial temblor that struck at 5:56 p.m. registered upper 6 on the 7-point Japanese scale in Ojiya, Niigata Prefecture, followed by aftershocks of the same scale, the Meteorological Agency said. It warned of further powerful aftershocks.
At 6 p.m., the government established a disaster task force at the prime minister's official residence.
In Tokamachi, Niigata Prefecture, a man in his 30s died after being buried under the rubble of a wall that collapsed at a restaurant. Some 50 to 60 injured people have been admitted to Niigata Prefectural Tokamachi Hospital, local government officials.
In Ojiya, one person was confirmed to have been killed in the disaster. A house collapsed and a landslide triggered by the quake buried a number of cars. About 30 injured people were rushed to a local hospital. Police officers rushed to the landslide scene to rescue people trapped in a car while trying to confirm if anybody in the collapsed house was injured.
Ojiya Municipal Government officials cannot immediately confirm the extent of damage because many roads in the town have been damaged, according to national government officials.
The Fire Defense Agency received a report that several people were buried alive in Kawaguchi, and is trying to confirm the information, officials said.
In Nagaoka, a fire broke out at three houses, municipal government officials said. One of the fires has already been extinguished. The local fire department dispatched ambulances to 20 locations to transport residents injured in the quake.
Two coaches of a 10-car-long bullet train, Toki No. 325 superexpress that left Tokyo for Niigata, derailed between Urasa and Naganoka station on the Joetsu Shinkansen Line and is at a standstill, its operator, East Japan Railway Co. said. However, the train did not topple over as it was slowing down toward Nagaoka Station, and none of some 150 passengers or crewmembers was injured in the accident.
All the expressways in Niigata Prefecture have been closed. Electric power supply has been completely suspended to at least some 250,000 households in extensive areas of Niigata Prefecture, including Ojiya and Kashiwazaki.
The focus of the quake, which is estimated at 6.8 on the open-ended Richter scale, was located about 20 kilometers below the ground in central Niigata Prefecture.
The temblor was followed by aftershocks, three of which registered upper 6 in some areas of Niigata Prefecture. (Compiled from Mainichi and wire reports, Japan)
