By injecting mice with pneumococcus bacteria that had first been heated, Griffith proved genetic material was environmentally heritable. Please see link below for detailed treatment.
The allele frequency in a population determines the genotype frequency. Allele frequency refers to how often a particular version of a gene appears in a population, while genotype frequency is the proportion of individuals with a specific genetic makeup. Changes in allele frequency can lead to changes in genotype frequency within a population over time.
Frederick Griffith was a British bacteriologist. In January 1928, he reported what is now known as Griffith's Experiment, the first widely accepted demonstrations of bacterial transformation, whereby a bacterium distinctly changes its form and function.
Phenotype does not determine genotype. Actually a genotype includes an organisms entire hereditary information. A phenotype is simply the organisms actual observed properties including appearance, development and behavior.
No, the genotype for a gray bodied fly cannot be determined just based on its phenotype alone. Grey body color could result from different genetic combinations, such as a homozygous dominant genotype (GG), a heterozygous genotype (Gg), or other genetic variations. Additional information or genetic testing would be needed to determine the specific genotype for the gray body color.
no not always due to some phenotypes having more than one gene sequence that affects it, eg; the base sequence for a certain enzyme's synthesis could be TTT but by substituting a T with a C to make TTC in mutation could still be a code for the same enzyme...
Horizontal gene transfer is the process of genetic material being transferred between organisms that are not parent and offspring. This transfer can lead to changes in both the genotype (genetic makeup) and phenotype (observable characteristics) of the receiving organism.
Bacteria and viruses change the genotype of an organism through mutation. Mutations are heritable changes in DNA and RNA that changes the genes..
Mutations can cause changes in the genotype by altering the DNA sequence. These changes can then affect the phenotype by influencing the expression of certain traits or characteristics in an organism.

The genotype of a particular trait may be changed by the environment that the organism lives in. The organism has to adapt, and therefore, the characteristic changes slightly, passing this change on to the next generation.
Yes, but the animals are uncomfortable about this fact because Mr. Frederick (who represents Germany) is a human. At first, Napoleon is against Frederick and changes the slogan from "Death to Humanity" to "Death to Frederick". He later changes it to "Death to Pilkington" without warning.

Because peoples appearances changes as their body changes.
A company changes accounting principle.
gwapo c FREDERICK ^^
Yes, the ratios of genotypes for a specific trait can change if allele frequency changes.
It will die off if the environmental condition changes drastically. This is because if the gene pool is large, i.e. lots of variation in the genotype, natural selection causes some to die off but others can still survive if they have characteristics adapted to the new conditions. But if the genotype is limited, they sadly don't have "other forms" of genes, so if the new condition is bad for them, the population is equally affected and they die.
