Answer:
DNA does not support the hypothesis that coelacanth is the closest relative to amphibians.
Explanation:
After several DNA analyzes, including analysis of mitochondrial DNA sequences, scientists found that coelacanth DNA does not support the idea that it is the closest relative of amphibians. However, other molecular analyzes, looking at the DNA of other living beings, concluded that the pulmonary fish is, in fact, the closest relative of the amphibians, with Coelacanth being the closest relative of the tetrapods.

Submucosa, serosa
The submucosa layer of the gi tract wall contains glands, blood vessels, and nerves, whereas the serosa layer is the outermost layer that protects the GI tract.
The gastro intestinal tract (GI) is a series of hollow organs that extend from the mouth to the anus. The hollow organs of the GI tract include the mouth, esophagus, stomach, small intestine, large intestine, and anus. The submucosa layer of the GI tract wall contains blood vessels, glands, nerves, and lymphatic vessels. The serosa layer is the outermost layer of the GI tract. The serosa layer is made up of areolar connective tissue that protects the GI tract.
A) If red hair were a recessive trait, it could be inherited in two ways: 1) from heterozygous parents who both carry the red hair allele (the chances of having a child with red hair would be 25%), or 2) from red haired parents who are both homozygous (100% chances of red haired offspring).
B) If red hair were a dominant trait, it could be inherited only if at least one of the parents had red hair. There's 3 variables: 1) If both parents were heterozygous, they would have a 75% chances of having red haired children; 2) if one parent were heterozygous and the other were homozygous dominant, all of their offspring would have red hair; and 3) all children would be red haired if both parent were homozygous, one dominant and the other recessive.
This exercise is an example of Mendelian inheritance which states that the genes inherited from parents are separated into gametes in equal frequency. Each parent "donate" an allele to their offspring; this allele could be physically expressed or not depending on it being dominant or recessive (this means: silent) and if the parents being homozygous or heterozygous. Heterozygous individuals have two different alleles (one dominant and one recessive), while homozygous can have either 2 dominant alleles or 2 recessive ones.
