Mendel concluded that pea traits like flower color were determined by separate units. From the results, Mendel proved that all traits do not blend. For instance, purple flowers mixed with white flowers did not produce pink flowers.
Since all of the offspring have the purple phenotype, this tells us that the purple allele is dominant to the white allele. ... This means that 75% of the offspring displayed the dominant phenotype of purple flowers, and 25% displayed the recessive phenotype of white flowers.
Two pea plants, both heterozygous for flower color, are crossed. The offspring will show the dominant purple coloration in a 3:1 ratio. Or, about 75% of the offspring will be purple.
Mendel's Results
Mendel noted the ratio of white flowered plants to purple-flowered plants was about 3:1. That is, for every three purple-flowered plants, there was one white flowered plant.
The answer is 46 chromosomes.
Before mitosis, cell duplicates its DNA material so there are 46 chromosomes in duplicates and in total there are 46 x 2 = 92 sister chromatids. During mitosis, sister chromatids first join in the middle of the cell and then separate towards the opposite sides of the cell. After they separate, there are 46 sister chromatids on the one side and 46 sister chromatids on the other side. Each sister chromatid at the end of cytokinesis actually represents the chromosome of the newly formed daughter cell.
Answer:
The chromosomes have coiled and become more compact.
Explanation:
Answer:
through changes in the availability or activity of the "helper"
Explanation:
This process involves many "helper" proteins, which make sure the ribosome is correctly positioned. Translation can be regulated globally (for every mRNA in the cell) proteins.
Answer:
hope it's right
Explanation:
1)Cerebrum: is the largest part of the brain and is composed of right and left hemispheres. It performs higher functions like interpreting touch, vision and hearing, as well as speech, reasoning, emotions, learning, and fine control of movement.
2)Cerebellum: is located under the cerebrum. The cerebellum receives information from the sensory systems, the spinal cord, and other parts of the brain and then regulates motor movements. The cerebellum coordinates voluntary movements such as posture, balance, coordination, and speech, resulting in smooth and balanced muscular activity.
