I am doing a test 16 questions it’s hard who has the answers I can’t find
UwU is correct on all of the immediate response questions. Not sure about the ones that have to be checked by a teacher though.
For the first question, the scientist is studying a plant species with codominant flower color genes. This means that when two different alleles for flower color are present, both traits are expressed equally. In this case, the scientist crosses a plant with red flowers (RR) and a plant with white flowers (WW).
To determine the possible flower color in the offspring, we need to consider the possible genotypes resulting from the cross:
- When the red flower plant (RR) is crossed with the white flower plant (WW), the possible genotypes of the offspring are RW (red) and RW (white).
Since the alleles for red and white flower color are codominant, the most likely outcome is that the offspring will have pink flowers (resulting from the expression of both the red and white alleles).
Therefore, the answer is C. Pink flowers.
For the second question, in order for a child to inherit a recessive genetic disease like sickle cell anemia, both healthy parents must carry the mutated gene that causes the disease.
Sickle cell anemia is caused by a recessive allele (s) that must be inherited from both parents for the disease to manifest. Healthy parents can be carriers of the disease if they have one copy of the mutated allele (Hs) and one copy of the normal allele (H).
The possible combinations for the parents' genotypes are:
- Both parents can be carriers (Hs) without showing symptoms of the disease.
- One parent can be a carrier (Hs) while the other is homozygous normal (HH).
So, the correct answer is C. Both parents must be carriers of the mutated gene that causes the disease.
