The degrees of freedom are equal to n – 1, where n is the number of different expected choose the correct answer from the following choices, and then select the submit answer button. answer choices phenotypes. genotypes. heterozygotes. alleles. homozygotes.

Phenotypes

Explanation:

Chi-square distribution is affected by the total number of independent categories present in an experiment. An increased number of total categories also increases the chi-square value. The total number of independent categories possible in the given experiment represents its "degree of freedom".

For example, a cross between two heterozygous tall pea plants gives a progeny of 1000 plants out of which 700 are the tall plants. And the total number of short plants would be 1000-700= 300.

Here, "tall plants" is an independent category while the number of "short plants" depends on the total number of tall plants.

Hence, the degree of freedom is calculated by following formula= "n-1". Here, "n" represents the total number of different categories, the phenotypes (tall and short plants are two possible phenotypes in the given example).

answer: 20 percent

the fish culture has become a developing commercial practice in developing countries which is already prominent in developed countries of the world. the major fish protein demand is being supplemented in developing countries is   fishing to meet the needs of the growing population. therefore, in some developing nations, the percentage of animal protein from fish in the diet can be as high as 20 percent.
