Answer:
The correct answer is - the phenotypic ratio would be 9:3:3:1.
Explanation:
The two traits that are dominant are free earlobe and straight thumb that are denoted by the E and T on their alternative recessive alleles attached lobe and hitchhiker thumbs denoted by the e and t respectively. The heterozygous condition will be EeTt.
The cross between EeTt and EeTt will produce gametes ET, Et, eT, and et by each. The phenotypic ratio of the cross would be 9:3:3:1, which means 9 out of 16 offspring will be dominant in both trait, 3 will be free lobe and hitchhiker thumb, 3 will be straight thumb and attached earlobe, and 1 will be recessive in both traits. For the cross please check the attached image.
Thus, the correct answer is - the phenotypic ratio would be 9:3:3:1.
White meat are usually found at the breast and wings while dark meat are found at the legs of the chicken.
<h3>What are types of poultry?</h3>
Poultry is the type of meat that is gotten from birds such as the Muscovy ducks, mallard ducks, turkeys, guinea fowl, geese, quail, pigeons, ostriches and pheasants.
Poultry meat provides the body with the following nutrients:
There are different type of poultry meat which include:
The white poultry meat are located at the breast and wings of the chicken and are known to contain 10% red fibres.
The dark poultry meat are located at the legs of the chicken and are known to contain 50% red fibres.
Therefore, although both white and dark poultry meat can be found in a bird, they are quite different because they contain different quantity of red fibres.

DDT was one of the first chemicals in widespread use as a pesticide. Following World War II, it was promoted as a wonder-chemical, the simple solution to pest problems large and small. Today, nearly 40 years after DDT was banned in the U.S., we continue to live with its long-lasting effects:
The energy Earth receives off the sun is Solar radiation
The correct answer is C) carboxysomes
Carboxysomes are polyhedral inclusion bodies that contain enzyme ribulose- 1,5-bisphosphate carboxylase/oxygenase (RuBisCO). This is responsible for the fixation of carbon dioxide in cyanobacteria. Carboxysomes have evolved as a consequence of the increase in oxygen concentration in the ancient atmosphere.
Thus, <em>carboxysomes are not energy reserves</em>, unlike another offered answers.
