The answer is: <span>A- Genes for body and wing size were on the same chromosome and inherited together</span>
Answer:
.................................
Answer:
<h2>A</h2>
Explanation:
1. Sickle cell anemia is an inherited condition, disorder (disease).
2. It is a recessive condition, in which red blood cell become mutated and converted to a sickle like shape, and there aren't enough healthy red blood cells to carry oxygen throughout the body.
3. This condition normally occur when, there is inheritance of two abnormal or mutated copies of the β-globin gene, one allele from each parent.
4. β-globin gene makes haemoglobin.
5. Sickle cell anemia results when glutamic acid being substituted by valine at position 6 ( in short E6V substitution).
6. So, it a single base-pair substitution in the gene encoding the beta subunit.
The complementary strand<span> for </span>DNA<span> must follow the base pairing and polarity rules. Pairing means that A=T and G=C. Polarity means that the </span>strands<span> have to run in opposite directions. First </span>write<span> the correct base pairing </span>below the original sequence<span> and label the 5' and 3' ends.</span>
