Answer: The correct option is B.
Will genetically modified crops increase profit for farmers?
Explanation:
This is because genetically modified crops are produced to achieve a particular advantage. Genetically modified crops are produced with some traits that are beneficial to Agriculture. Farmers choose genetically modified crops in order to increase yield, and produced crops that are resistant to certain diseases. These genetically modified crops are produced because of the traits that increase crop yield when farmers plant them it will increase the profit of farmers.
Answer:
chromosomes.
Explanation:
Chromosomes occur as strands of long-chain protein molecules called DNA. Chromosomes are made up of two strands each called chromatid . The chromatids are joined at a point called centromere. During prophase, the chromosomes become tightly coiled and so appear shorter and thicker. Parts of chromosomes form functional units called genes which determine different activities of the cell. Genes are hereditary and can be transmitted from parent to off-spring.
The expression which is the correct way to calculate the frequency of the dominant allele is 134/200. Thus, the correct option is D.
<h3>What is Allelic frequency?</h3>
The allelic frequency may be defined as the sum total of all the alleles of a gene in a population. It represents the overall genetic diversity within a population.
The allelic frequency is calculated by the formula when the genotypes are given in number. It is as follows:
2 × Number of Purebred dominant + Number of heterozygous/ 2× Total number of individuals in a population.
∴ Allelic frequency of dominant allele = 2 × 50 + 34/ 2× 100 = 134/200 = 0.67.
The allelic frequency of the Dominant allele is 0.67 while the allelic frequency of the recessive allele is 0.33.
Therefore, it is well described above.
