No it is not clear cutting is more beneficial
I think it is A if not it is B
Answer:
A. Genotypes: Rr
Phenotypes: All Pink
B. Genotypes in the F2 generation: RR, 2Rr, rr
Phenotypes: red, pink and white
C. 1RR (red): 1Rr (pink).
D. 1Rr (red) : 1rr (white).
Explanation:
This question involves one gene coding for flower color in snapdragon plants. The allele for red color (R) is incompletely dominant over the allele for white color (W), to form an intermediate pink color (RW).
A. If a red-flowered plant (RR) is crossed with a white-flowered plant (rr), the genotypes of the offsprings will be Rr with a pink color phenotype.
B. In the F2 generation i.e. Rr × Rr, the following will be produced: RR (red), 2Rr (pink), and rr (white).
C. if a red-flowered plant is crossed with a pink-flowered plant, the following will be produced: 1RR (red): 1Rr (pink).
D. if a pink-flowered plant is crossed with a white-flowered plant, the following will be produced: 1Rr (red) : 1rr (white).
Answer:
See the answer and explanation below, please.
Explanation:
The plasma membrane is composed of:
- Lipid bilayer (highlights: phosphoglycerides such as phosphatidylethanolamine or cephalin, phosphatidylcholine or lecithin, phosphatidylinositol and phosphatidylserine; sphingolipids formed by ceramide and fatty acids, and cholesterol)
- Proteins: integral, peripheral and membrane fixed to lipids.
- Glucids: covalently bound to proteins or lipids; they can be poly or oligosaccharides. They form the glycocalix on the outside of the membrane and its function is to support the membrane and cell recognition.
