A feature of a pedigree that indicate that a certain trait is a dominant trait is that one of the parents always have to have the trait.
There are, however, autosomal dominance and X-linked dominance.
For an autosomal dominant trait:
- Appears equally frequent in both sexes.
- Both sexes transmit the trait.
- Present in all generations.
- When one parent has the trait and the other doesn't, approximately half of the offspring will present the trait.
For a X-linked dominant trait:
- Both male and females can present the trait, but more females usually present it.
- Sons with the trait always have a mother that presents the trait as well.
- Daughters with the trait always have either a mother or father that presents the trait, or both.
- Fathers with the trait always have daughters with the same trait.
The double helix is a description of the molecular shape of a double-stranded DNA molecule. In 1953, Francis Crick and James Watson first described the molecular structure of DNA, which they called a "double helix," in the journal Nature.
In eukaryotic cells, the theoretical maximum yield of ATP generated per glucose is 36 to 38, depending on how the 2 NADH generated in the cytoplasm during glycolysis enter the mitochondria and whether the resulting yield is 2 or 3 ATP per NADH.Jun 26, 2001
Answer: Sea walnuts are marine invertebrates. They belong to the genus Mnemiopsis.
Explanation:
These animals have stinging tentacles like jelly fish and they often cast up or come to the sea shores where if they come in contact with humans can harm them by stinging.
The barrier if kept along the side of the sea shore and not allowing humans to reach to the shore can help in preventing the harm from these animals. The introduction of the predatory animals in the sea can also help in reducing their population.
The three benefits for removing the sea walnut:
1. The population of other species will increase as sea walnut is an invasive species.
2. The balance of the marine ecosystem can be maintained.
3. Humans can be protected from the harm caused by these animals.
Answer:
how old the star is
Explanation:
There are many characteristics that affect the brightness of stars. If two stars are the same temperature, same age, and same distance from the Earth, the larger one will appear brighter. If the temperature, age, or size is different, the one closest to Earth will appear brighter, even if that is the smaller one.
