Answer:
Darwin and Lamarck's theory is different but they were also very similar. Both of them thought that the organism changed, and they are very helpful for the organism to survive. These characteristics are also passed to their young generation.
Darwin theory state that an organism gets the helpful variation before the changes in the environment, Lamarck's theory said that organism gets variation after the change in the environment.
Lamarck's stated that giraffe got long neck when the food on the ground ran out. In order to get the food they stretch out their neck to get food. Darwin thought organism changed by chance, at the time when they are born and before the change in the environment.
Answer:
Height is affected by multiple pairs of genes on different chromosomes.
Explanation:
The quantitative traits are those whose inheritance pattern is the result of the action of multiple genes that act together with the environment. The distribution of quantitative traits in the population follows a bell-shaped curve, which is referred to as normal distribution or Gaussian distribution. These traits are 'quantitative' because they vary among individuals in the population to produce a continuous range of phenotypic values. Examples of quantitative traits include, among others, metabolic rate, height, and weight.
The information that bacteriophage cocktail significantly reduces contamination of lettuce and beef with Escherichia coli o157:h7, but does not protect against recontamination was demonstrated by the group of scientists. The suggest that this might be due to unsanitary handling of the foods post processing.
