What is the phenotypic ratio of the offspring when a man who has type A blood, and whose mother had type O blood, marries a woma
Vladimir [108]

Answer:

The correct answer is - 2 type A : 1 type AB : 1 type B

Explanation:

The pattern of the inheritance in the ABO blood group system is the example of the multiple alleles and codominance. There are three alleles in this sytem that determines what blood group would be in an indvidual that are; IA, IB, and IO. The allele IO is a recessive allele to both IA, and IB alleles whereas IA and IB are show codominance when present in heterzygous condition.

Genotype of a person with “A” blood group can be IA IO  or IA IA but as it is given that the mother of the male with A bglood group is O blood group which means there must be a IO allele would be present in the male too so the genotype would be IAIO.

The genotype of AB blood group mother would be IAIB as shows codominance. so the cross between these woulde be as follows:

IA IO  x IA IB

Gametes :

IA  IO , and IA  IB

  IA       IO

IA    IAIA    IAIO

IB    IAIB    IBIO

phenotypic ratio = 2 A group : 1 AB group : 1 B group

What phase comes after the production of a sporophyte in the alternation of generations?
AleksAgata [21]
The gametophyte era starts with a score created by meiosis. The spore is haploid, and every one of the cells gotten from it is likewise haploid. At the appointed time, this multicellular structure produces gametes — by mitosis — and sexual proliferation then creates the diploid sporophyte era.

Precise measurements are important for scientific accuracy. Use the game to explain why precise measurement of reactants is impo
lys-0071 [83]

Answer: Precise measurements are important for Scientific Accuracy in order to get correct results

Explanation:

Precision is how close the Agreement is between repeated measurements under the same conditions. For example, if a measured value 36.7cm has three digits, or significant figures. Significant figures indicate the precision of a measuring tool that was used to measure a value

Accuracy is how close a measurement is to the correct value for that measurement.

When taking scientific measurements it is very important to be both precise and accurate. Bad equipment, human error can give inaccurate results.
