Let's use A as the dominant allele for green seed colour and a as the recessive allele for yellow seed colour.
If a yellow seeded plant is crossed with a heterozygote,
aa X Aa
the yellow seeded plant would only produce one type of gamete (a) while the heterozygote would produce two different types of gametes (A and a)
If we put this into a Punnett square, we will see that there two two possible genotypes for the offsprings. Either Aa or aa.
Since the allele for green seed is dominant, Aa will exhibit the green seed colour phenotype.
Hence, the chance of getting an offspring with green seed colour is 1/2, or 0.5
The right option is; B. performance
The performance phase of the self-regulation cycle is the actual learning phase in which the actual task is performed. During this phase, specific strategies that can help the learner become more successful is utilized. Learning is made through the self-control process which is combined with self-monitoring in order to redevelop the learning strategy and to improve the performance.
The genotype that will be given is going to big r and small r because the cross will be the same.
Answer:
E. Erwin Chargaff >> Discovered that there were equal amounts of the nitrogen bases A T and C G in a human body cell; concluded that A paired with T and C paired with G
B. Hershey and Chase>> Did experiments with viruses to determine that DNA, not protein, is the genetic material of a cell
A. Frederick Griffith>> Did experiments with S and R strain pneumonia bacteria to determine that DNA is the genetic material of a cell
C. Rosalind Franklin >> Took x-ray crystallography images of a DNA molecule.
Explanation:
Chargaff rules helped to determine the double helix structure of the Deoxyribonucleic acid (DNA), i.e., the genetic material of prokaryotic and eukaryotic organisms. Chargaff indicated that DNA from any species contains a 1:1 ratio of purine bases (Adenine and Guanine) and pyrimidine bases (Cytosine and Thymine). Hershey and Chase provided evidence that the DNA, instead of protein, is the hereditary material. Hershey and Chase used radioactive phosphorus-32 in order to label the DNA of specific bacteriophages (T2), and they discovered that the DNA was responsible to generate progeny inside infected bacteria (i.e., DNA was hereditary material). Frederick Griffith observed that DNA molecule was the transforming factor that could be transferred to innocuous <em>Streptococcus pneumoniae</em> bacteria in order to convert them into deadly bacteria. Finally, Rosalind Franklin obtained the first X-ray image that showed the diffraction pattern of a crystallized DNA molecule, which was used by Watson and Crick to propose that DNA had a double helix structure.
