<h2>
The correct answer is: Both parent must be PP.</h2>
Explanation:
- The given question states that for flower color of the violet plants there are three phenotypes possible, purple, light purple and white.
- The flower color coding gene is governed by two variants or alleles in which there is an absence of complete dominance of one allele over the other as, if complete Mendelian dominance was there, only two phenotypes for flower color would have existed, purple and white, without the existence of any intermediate color, light purple.
- This indicates the existence of a Non-Mendelian pattern of inheritance with respect to the gene encoding for the violet flower color.
- As the intermediate phenotype of flower color is light violet, it indicates that in these plants neither of the two alleles are capable of showing dominance and this is an example of Incomplete dominance.
- Let the two alleles of the flower color coding gene be: P and p.
- Then the possible genotypes are: PP, Pp, pp.
- The corresponding phenotypes are: Purple, Light purple and White.
- Crossing all possible parents,
1. P P
P PP PP
Phenotypes (Purple) (Purple)
P PP PP
Phenotypes (Purple) (Purple)
2. P P
P PP PP
Phenotypes (Purple) (Purple)
p Pp Pp
Phenotypes (Light Purple) (Light Purple)
3. P p
P PP Pp
Phenotypes (Purple) (Light Purple)
p Pp pp
Phenotypes (Light Purple) (White)
4. P P
p Pp Pp
Phenotypes (Light Purple) (Light Purple)
p Pp Pp
Phenotypes (Light Purple) (Light Purple)
5. P p
p Pp pp
Phenotypes (Light Purple) (White)
p Pp pp
Phenotypes (Light Purple) (White)
6. p p
p pp pp
Phenotypes (White) (White)
p pp pp
Phenotypes (White) (White)
- According to the results of the above crosses, we find that the plant breeder should use such parents which are homozygous for the P allele, that is, both the parents must have the PP genotype. Then only all the offspring produced by crossing these parents will develop purple colored violet only.
Answer:
The appearance of the mycobacterium is like rod shaped.
Explanation:
The structure of mycobacterium is rod liked and it is purple in color. The meaning of the word mycobacterium is fungus bacteria because it resembles with the fungus in its structure and appearance. Cell wall is the cell component which correlate with mycobacterium. The structure of cell wall is thick and made up of several layers of peptidoglycan which is formed from sugar and amino acid molecules.
The mitosis is an interesting process, in which we have a type of cell division were the end result is two identical daughter cells, both of which have the same amount of chromosomes as the parent cell.
This process can be found in the growth of the tissue.
The process of mitosis can be seen as a sort of cellular immortality because the cell is able to divide itself, thus create two identical cells from itself. Those two cells are able to do the same, and they can constantly double and create more and more cells that identical to them, which in a way comes as an extension of the life of the initial parent cell all the way.
1. Nevada day is a hold day in the state of Nevada and it’s celebrated bc it’s a state holiday
3. Carbon cycle is a series of the environment going in a process of how the earth invokes
Answer:
1. A block start in 50M freestyle:ATP-CP
2. An all day walkathon - Fats
3. A marathon- carbohydrates and ATP-CP
4. A soccer match - carbohydrates and fats
5. A 5KM run - carbohydrates
Explanation:
Creatine phosphate, CP is a small source of energy which depletes ver fast but is backed up by ATP storage. This is why they are used in very low exercises that is, it can be resynthesized to ATP by the enzyme creatine kinase to replenish depleted ATP levels.
But the major sources of energy during exercise are carbohydrates and fats.
During the medium to low intensity exercise, the bulk of energy required by the muscle is provided by oxidation of fatty acids while for high intensity exercises, carbohydrates are needed so as to be broken down to give glycogen with the generation of ATP.
