Answer:

The correct answer would be - the ratio of phenotypes in an organism cross will tell if the genes are linked or not.

Explanation:

In this question, we perform a test cross with a fruit fly that is heterozygous If we perform a test cross between two parents with identical heterozygous genomes AaBb.

If there is no recombination found in the offspring of this cross it means there are no linkage of genes present.  And if there are new or recombinant phenotypes present it means that there are genes linked together.

1. How can we identify a market for vegetables? Write.
Ratling [72]

1.

Marketing is one of the most important factors in determining the success of any fruit and vegetable farming enterprise. Marketing includes all the operations and decisions made by producers. These decisions range from deter-mining the most marketable crops for production to deciding how to best deliver quality produce to the consumers at a profit. However, contrary to popular belief, marketing does not begin after a crop is produced. Instead, marketing alternatives need to be considered even before production takes place.

2.

Recent environmental and food safety concerns in the United States produce sector have brought about increasing interest in organic fruit and vegetable production as an alternative to traditional fruit and vegetable enterprises. As a result, the production and marketing of organic crops has expanded steadily during the 1980s. However, as more organic producers enter the industry and it becomes more and more competitive, existing producers are forced to become better growers and more effective marketers.
