Heritability is a measure that is used to estimate the variation of phenotypic traits (observable traits) in a given population due to the variation or changes in the genetic make up (genotype) among certain individuals. some of these traits includes color blindness, tongue rolling and curly hair among others. However, some traits such as nearsightedness are caused or influenced by the changes in the environment and therefore Heritability is not a factor to consider when dealing with such traits.
Answer:
Explanation:
Hernias are cuts in the muscles that makes the body bulge out. It can occur in the stomach region where intestine lies leading to its bulging out. Hernias has been traced back to early years and until recent it still exist.
Hernia are mostly common in man with little traces in woman. Some hernia are due to some congenital defect and could be found in new born. It is characterized by heart burn,cough, pressure on the affected part.
Hernia are said to be genetic, and this has lead to the continuity in human nature and not its reduction. Hernia have claim some life's especially the severe ones if not properly treated, some people have died in the theater room while be operate upon while some people are in sever pain of the disease. Hernia as at 2015 is present in 18.5million people and has caused death of about 59,800.
Answer:
See below
Explanation:
Marie Curie died of aplastic anemia in 1934. Aplastic anemia is an autoimmune disease in which the body fails to produce blood cells in sufficient numbers. Blood cells are produced in the bone marrow by stem cells that reside there. Aplastic anaemia causes a deficiency of all blood cell types: red blood cells, white blood cells, and platelets.
Fatigue is a symptom of aplastic anemia as the blood doesn't have the necesarry red blood cells to transport the oxygen to the organs.
Rapid heart rate happens because the body senses the decrease of oxygen's concentration and the hearts beats faster to provide the organs of oxygen.
Pale skin happens because the blood vessels are contracted in order to provide oxygen to the important organs of the body as the brain and heart. It means that less blood reaches the face and it shows as pale skin.
Prolonged bleeding from cuts happens because there aren't enough platalets to produce a blood clot to stop the bleeding.
Dizziness happens because there is not enough oxygen arriving to the brain.
If she is A negative, she can only receive blood from others A negative donors, or O- donors. This is because she has antibodies to B, and to groups that have the protein Rh (+). So she can't receive blood either B nor Rh+.
Answer:
Option E, Floppy ears are dominant over straight ears; coat color is determined by incomplete dominance
Explanation:
Let the allele for floppy ears be "F" and the allele for straight ears be "f"
And Let the allele for black coat color be "B" and the color for white coat color be "b"
Now, the cross is carried out between the first group having floppy ears and white coat color (FFbb) and the second group having straight ears and black coat color (ff BB)
The 16 offspring have genotype FfBb
Phenotype of 16 offspring is Floppy ears and grey coat
Ff represents the floppy ear , thus "F" is dominant over "f"
Bb represents the grey color which is a case of incomplete dominance in which none of the real trait i.e black or white is expressed.
Hence, option E is correct
