a man with blood group A marries a woman with blood group O and their daughter has blood group O. Is this information enough to
Nonamiya [84]
This information is not enough to tell which of the traits-blood group A or O is dominant.
It is known that blood groups A and B are codominant, which means both will express if found together in a heterozygote. However, blood group O is recessive. But from this information, you can conclude that blood group O is dominant. Why is that so?
Let's imagine that father's genotype is AA and mothers' genotype OO and cross them:
Parents:               AA    x    OO
Offspring:      AO    AO   AO    AO
Since we have information that daughter has blood group O, we can conclude that O is dominant over A and mask it. This is not true! In this case, the daughter will have blood group A.

Mother's genotype surely is OO (because O allele is recessive, so to express a recessive trait both alleles must be recessive). But, the father cannot be AA, because it must give O allele to the daughter so she can have genotype OO and blood group O. So, the father's genotype is AO.  Let's take a look at that crossing:
Parents:         AO   x    OO
Offspring:   AO   AO   OO   OO
Thus, in this case, daughter can have genotype OO and blood group O.

summary of 2 main parts of photosynthesis (light-dependent reactions and light-independent reactions/Calvin Cycle). Be sure to e
Alex_Xolod [135]

Explanation:

Photosynthesis is a process taking place in the green plants which are involved in the formation of the glucose molecule using Carbon dioxide and water in the presence of sunlight.

The process of photosynthesis takes place in two phases:

1. Light-dependent phase

2. Light independent phase

<u>Light-dependent phase </u>

Light-dependent phase takes place in the thylakoid membrane where the Photosystem I and II are present.

The photosystem II absorbs the sunlight of 680 nm wavelength which excites the electron of the chlorophyll. The electron moves in the photosystem and through the reaction center-exit the photosystem and enters the electron transport chain.

The electron is then transferred via the electron carriers like plastoquinone, cytochrome, and plastocyanin and is transferred to photosystem I which absorbs the light at 700 nm. From here the electron is taken by ferrodoxin and form NADH.

The electron then reaches the ATP synthase and forms the ATP molecules thus ATP and NADPH are formed in the reaction but the loss of electron in chlorophyll is fulfilled by the water molecule which on hydrolysis provides the electrons and stabilize the structure.

<u>  Light independent phase </u>

The phase during which the Rubisco enzyme binds with the carbon dioxide and forms 3-PGA. This 3 PGA is then reduced to G3P which requires the 6 ATP molecules. The G3P molecule then forms 1 molecule of glucose and the Rubp is again regenerated.

Genetic variation makes individuals within a species different. Fertilization results in each offspring having a copy of each ge
murzikaleks [220]

Genetics is a branch of biology concerned with the study of genes, genetic variation, and heredity in living organisms.[1][2][3]

The discoverer of genetics is Gregor Mendel, a late 19th-century scientist and Augustinian friar. Mendel studied "trait inheritance", patterns in the way traits are handed down from parents to offspring. He observed that organisms (pea plants) inherit traits by way of discrete "units of inheritance". This term, still used today, is a somewhat ambiguous definition of what is referred to as a gene.

Trait inheritance and molecular inheritance mechanisms of genes are still primary principles of genetics in the 21st century, but modern genetics has expanded beyond inheritance to studying the function and behavior of genes. Gene structure and function, variation, and distribution are studied within the context of the cell, the organism (e.g. dominance), and within the context of a population. Genetics has given rise to a number of subfields, including epigenetics and population genetics. Organisms studied within the broad field span the domains of life (archaea, bacteria, and eukarya).

Genetic processes work in combination with an organism's environment and experiences to influence development and behavior, often referred to as nature versus nurture. The intracellular or extracellular environment of a cell or organism may switch gene transcription on or off. A classic example is two seeds of genetically identical corn, one placed in a temperate climate and one in an arid climate. While the average height of the two corn stalks may be genetically determined to be equal, the one in the arid climate only grows to half the height of the one in the temperate climate due to lack of water and nutrients in its environment.
