Allele frequency is determined by looking at the dominant and recessive allele of a genotype.
Using the given, we can come up with the following computation for the allele frequency:
allele A = 100/300 allele B = 50/300 allele O = 150/300
Hence, the frequency of allele A is 0.33 or 33%, allele B is .17 or 17% and allele O is 0.50 or 50%.
Answer:
The parent's genotypes are:
Ddpp - tall, white parent
ddPp - dwarf, purple parent.
Explanation:
This question involves two different genes coding for height and flower color in pea plants. The alleles for tallness (D) and purple color (P) are dominant over the alleles for dwarfness (d) and white color (p) respectively.
According to this question, a tall plant with white flowers is crossed with a dwarf plant with purple flowers to produce the following proportion of offsprings: 1/4 tall purple, 1/4 tall white, 1/4 dwarf purple, and 1/4 dwarf white.
Since some of the offsprings contain recessive alleles for both or either genes, the dominant traits of the parent is controlled by an heterozygous genotype. This means that the tall plant with white flowers has a genotype: Ddpp while the dwarf plant with purple flowers has the genotype: ddPp. In a cross between Ddpp × ddPp, 1/4 of each combination of alleles is produced in the offsprings (see punnet square in the attachment).
Answer:
What role does kudzu most likely play in the environment in the United States? Kudzu experiences loss due to overeating by livestock. Kudzu is very susceptible to harsh winter conditions. Kudzu outcompetes native plants for sunlight and nutrients
Explanation: yep
San Francisco has an opportunity to reap tremendous economic, environmental, and health benefits by adopting recent advances in “green building”—benefits that will only increase in value over time. Many standard building design, construction, operation, and renovation practices are outmoded, inefficient, costly, and have adverse health and economic effects. The shift to new, environmentally sensitive practices would maintain San Francisco’s status as a leader in urban planning and environmental innovation. A shift to green buildings is also vital to enhancing San Francisco’s livability for its residents, workers, and visitors.
DNA replication
DNA replication is the process by which DNA makes a copy of itself during cell division. The first step in DNA replication is to 'unzip' the double helix structure of the DNA? molecule. ... The two separated strands will act as templates for making the new strands of DNA
