What is the genotype of a heterozygous person with a cleft chin?

Answer:

Cc

Explanation:

A cleft chin is an example of a trait that is controlled by genetics. A cleft chin is when there is a dimple in the chin which arises when the two sides of the jaw don’t completely fuse together. Famous people with cleft chins are Henry Cavill, John Travolta and Niall Horan.

A cleft chin is generally thought to be a dominant trait. That means, if an individual carries one copy of the cleft chin gene (heterozygous), then they will display the trait.

There are three options: an individual can be homozygous dominant (CC), homozygous recessive (cc) or heterozygous (Cc). A heterozygous person will always have 2 different alleles (for any trait, not just cleft chin). In this case, a heterozygous person will have a cleft chin, because it is dominant. Therefore, an heterozygous person with a cleft chin will be Cc

Remember, the letter doesn't matter - they could also be denoted as Bb, Qq, Rr, Ff. The letter is arbitrary.

Explanation:

As illustrated in this question, Gregor Mendel used the color trait of pea plant to discover his law of dominance.

The results Mendel obtained during his experiments. It showed that if you cross two plants that were true breeding for different colors (purple and white), the offspring or first generation (F1) would be HETEROZYGOUS (Pp) instead of true-breeds, and all were PURPLE in color.

Interestingly, when he crossed two of these F1 plants (Pp × Pp), their offspring did not all come out PURPLE, instead he obtain a ratio of 3 purple-flowered plant for every 1 white-flowered plant. He concluded that the “heritable factor” for the RECESSIVE trait (white flowers) was not destroyed in the F1 generation. Instead it had been MASKED by the “heritable factor” of the DOMINANT trait (purple flowers).

Difference and axplanation of MI and cardiac arrest
kondaur [170]

In myocardial infarction, blood flow is blocked in the heart, causing a heart attack to occur.

In cardiac arrest, the heart malfunctions and causes the heart to stop beating unexpectedly.

You can think of a myocardial infarction (MI) as a circulation issue, whereas cardiac arrest is an electrical issue.

zvonat [6]
The answer for the above question is the Avascular Necrosis. It occurs as an interruption in the blood flow within the bone resulting in the death of the hematopoietic cells, osteocytes, and marrow fat cells making up the bony structure. It is also called osteonecrosis or ischemic bone necrosis, which occurs when there is loss of blood to the bone, since the bone is a living tissue that needs blood, this interruption of blood supply will result to the death of the bone.

Setler [38]

Answer:

Yes

Explanation:

If both of the parents have a recessive trait that decides fur color, then there is a 25% chance that the offspring will receive the recessive traits from each parent and will not receive either of the dominant traits.
