Answer:
<u>Two different alleles come together and produce both trait forms</u>. Two different alleles come together and produce a trait form that is neither dominant nor recessive. a chromosome that determines the X or Y of an organism.
The trait that is dominant or reccessive can be obtained by the use of a Punnet square or by the use of the conventional crossing of allele pairs.
<h3>What are traits?</h3>
The term traits refers to the expressed characteristics of an organism. The dominant trait is expressed while the reccessive trait is not expressed.
The trait that is dominant or reccessive can be obtained by the use of a Punnet square or by the use of the conventional crossing of allele pairs.

Answer:
Mutualism: both partners benefit. An example of mutualism is the relationship between the Egyptian plover and the crocodile. In the tropical regions of Africa, the crocodile lies with its mouth open. The plover flies into its mouth and feeds on bits of decaying meat stuck in the crocodile’s teeth. The crocodile does not eat the plover. Instead, he appreciates the dental work. The plover eats a meal and the crocodile gets his teeth cleaned. Coincidentally, the Egyptian plover is also known as the crocodile bird.
Commensalism: only one species benefits while the other is neither helped nor harmed. For example, remora fish are very bony and have a dorsal fin (the fin on the back of fish) that acts like a suction cup. Remora fish use this fin to attach themselves to whales, sharks, or rays and eat the scraps their hosts leave behind. The remora fish gets a meal, while its host gets nothing. Selfish, sure, but neither gets hurt.
Parasitism: One organism (the parasite) gains, while the other (the host) suffers. The deer tick is a parasite. It attaches to a warmblooded animal and feeds on its blood. Ticks need blood at every stage of their life cycle. They also carry Lyme disease, an illness that can cause joint damage, heart complications, and kidney problems. The tick benefits from eating the animal's blood. Unfortunately, the animal suffers from the loss of blood and nutrients and may get sick.
Explanation:
<em>An organism's genetic code is determined by the sequence of nucleotides of the DNA. </em>
What I mean is that it determines the nitrogen bases along a gene.
