What is a marine protected area?

In a particular family, one parent has Type A blood, the other has Type B. They have four children. One has Type A, one has Type

AlladinOne [14]

Answer:

The correct answer is -

Parental genotypes: AO & BO

Children genotypes: AB, AO, BO, and OO

Explanation:

In the human blood group system, more than two types of alleles are present that lead to the existence of four blood groups in the human population.

Here, A and B alleles are co-dominant while the O allele is recessive to both A and B alleles in the ABO system.

The cross depicting the genotypes of children is

IA IO

IB IAIB IBIO

IO IAIO IOIO

In this cross, we get the same result as given in the question -

One parent has A and the other has B type blood while the children have all four types of blood groups One has Type A, one has Type B, one has Type AB, and the last has Type O. It is possible only when parents are heterozygous in their genotypes and not expressing codominance.

Which hold water until it is needed?

Svetradugi [14.3K]

B, reservoirs.

Dams are used to conserve water and to convert it into hydroelectric energy.

Aqueducts are used to move water from one source to another, think sort of like irrigation.

Valleys are plains of grass, has nothing to do with water.

Reservoirs however, are used to <u>reserve</u> water, <u>Reserve</u>oirs.

How does teaching the public about energy conservation help decrease air pollution?

Dimas [21]

It reduces the demand of electricity because if people want to decrease the amount of air pollution they would stop using things that would cause pollution for example, people stopping to use gasoline powered cars and use electric cars more, therefore the demand for electricity will go low since lesser people will be using it.

Explain how you could determine wheater seeds in packets of round pea seeds have a genotype rr or rr

mezya [45]

I think you mean Round could be RR or Rr (round is dominant to wrinkled)
R=round
r=wrinkled
RR would be round phenotypically
Rr would be round phenotypically
To determine if they are RR or Rr you should perform a backcross with a wrinkled mutant!
I put a picture to demonstrate this.
If they are RR then if you cross with rr you would only get phenotypically Round pea plants.
If they are Rr then if you cross with rr you would get 50% round and 50% wrinkled. Any wrinkled? Definitely the heterozygote Rr!!
