Scientist rely on <em>Biology </em>concepts when researching crop production and medicine.
<span>The vibrations are then sent to three tiny bones in the middle ear: the malleus, incus, and stapes. These bones then amplify the sound vibrations and send them to the cochlea, a snail-shaped structure in the inner ear. The vibrations then cause the fluid inside the cochlea to ripple along the basilar membrane. This ripple stimulates the hair cells that sit on top of the basilar membrane.</span>
Answer: The correct option is D, because a person having sickle cell anemia must be homozygous for the trait.
Explanation: Sickle cell disease is autosomal inherited disease. In this disease the shape of red blood cell change from round to crescent shape, as a result it become unable to carry oxygen because it can not pass through capillaries. When
Glutamine amino acid is replaced by
Valine the shape of hemoglobin become sickle shaped.
Genetics of Sickle cell anemia:
This disease appears in homozygous recessive from. Genes for sickle cell is represented by
"S" while for normal it is represented by capital
"A". If a carrier man marry a carrier woman then 50% of child will be sickle celled, 25% will be normal and 25% will be carrier for disease as shown in the figure
