These are called multiallelic traits. If GGHHII was crossed with gghhii, what would the genotype for every offspring be?
GenaCL600 [577]

Answer:

In the crossing of individuals with multiallelic traits, the crossing of a GGHHII individual with a gghhii individual would produce offspring of hybrid individuals for all three traits whose genotype would be GgHhIi (option c).

Explanation:

The individuals GGHHII and gghhii are pure lines for each of the traits —multiallelic traits— they express, one of them having the three dominant traits and the other three recessive traits. The product of crossing two pure lines with dominant and recessive traits is an offspring of 100% heterozygous individuals.

This can be tested by making a Punnett square for this cross:

<u>GGHHII X gghhii</u>

Alleles     GHI        GHI

ghi         GgHhIi   GgHhIi

ghi         GgHhIi   GgHhIi

Thus the offspring in the cross of two individuals, dominant and recessive, for multiallelic traits G, H and I is GgHhIi

Which events take place in the light-dependent reactions of photosynthesis?
borishaifa [10]

The correct answer is : Light energy is captured by plants; light energy is converted to chemical energy.

In the process of photosynthesis, special pigment molecule called chlorophyll can capture the energy of the light, more specifically the photon. When a particle of light (a photon) with a specific energy reaches this pigment in the leaves of plants, the energy is transferred from the particle to the molecule, and the molecule becomes excited. This is the phase where the energy of the light is captured and transformed into chemical energy that can later be used to make sugars.

All of the later chemical processes that transfer the energy from the excited chlorophyll to the sugar molecules are not dependent on the light and can happen during the night as well.

<h2>Synthesizing antibodies</h2>

Explanation:

  • Antibodies are have proteins that are created by the insusceptible framework because of remote atoms that enter the body. These outside particles are called antigens, and their atomic acknowledgment by the safe framework brings about particular creation of antibodies that can tie the particular antigen. Antibodies are made by B-lymphocytes and circle all through the blood and lymph where they tie to their particular antigen, empowering it to be cleared from dissemination.  
  • Antibodies are explicit proteins that perceive almost any substance structure. During in vivo vaccination B cells are enacted by antigen. Antigen‐specific cells multiply and some separate into antibody‐secreting plasma cells. Quickly, B cells with explicitness for a realized antigen were combined with myeloma to make them everlasting. Hybridomas develop in culture uncertainly and emit monoclonal antibodies (mAbs) of an ideal particularity. Hybridoma innovation and counter acting agent building have contributed in Biomedicine to the analysis of malignancies, tissue composing, distinguishing proof of individual cell types, identification of cytokines, development variables and hormones.

TRUE OR FALSE: DNA sequences are exactly the same for organisms that are related to each other. (If false please explain).
aev [14]

Answer: False

Explanation:

DNA sequences can be similar for organisms that are related to each other but through various steps of meiosis like crossing over and law of independent assortment we can get genetic variations that lead to slight differences. We can also get differences in DNA sequences due to mutations.
