Answer:
75% probability
Explanation:
The father have the trait of sickle cell anemia which means he is a sickle cell dominant with a trait of dominant SS ( meaning he has displays the severe symptoms of sickle cell disease that occur in a person who has two copies of that allele i.e homozygous). While the mother is heterogygous which means that she has one abnormal allele of the hemoglobin beta gene represented as As.
Based on this notion, upon crossing of the traits the probabilities are<em> 75% Heterogygous trait and 25% homoxygous traits (i.e As, As, As, SS)</em>. Meaning 75% of the children will be unaffected by the Sickle cell anemia, while 25% will be affected by the anemia.
Answer:
D
Explanation:
I had this question before and this is the guaranteed answer
Explanation:
<h3> Possesses a well-developed brain and a vertebral column with eyes at the front of its head, - Possesses a four chambered heart and lays eggs, - It is an aboral herbivore, with a row of spines running down its back to its tail. Classify organism ‘A’ into is corresponding Phylum, Class and Genus. State clearly the features .</h3>
Chromosomes are thread-like structures located inside the nucleus of animal and plant cells. Each chromosome is made of protein and a single molecule of deoxyribonucleic acid (DNA<span>). Passed from parents to offspring, </span>DNA<span> contains the specific instructions that make each type of living creature unique.</span>
The start signal is AUG which codes fo methionine. The amino acid sequence will be as follows: <span>Met-Phe-Pro-Ser-Tyr-Pro-Lys-Asp-Lys-Lys-Glu. The first codon (GCC) codes for alanine but not in the amino acid sequence because it is not a start codon (the only start codon is AUG which codes for methionine).
