See the answer with the explanation below.
Explanation:
Assuming the allele for sickle cell disease is represented by S and the alternate, non-sickle cell version is A; AA would be <em>homozygous normal</em>, AS would be <em>heterozygous normal</em>, and SS would be a <em>sickler</em>.
a. <em>The genotype of the father in the first generation would be </em><em>AS</em>.
The father is heterozygous, since the mother is affected and the couple produced an affected child. The cross can be illustrated thus:
AS (father) x SS (mother) = AS, AS, SS, SS
b. <em>The genotype of the daughter in the second generation would be </em><em>SS</em><em> </em>since she is phenotypically affected for the disease.
c. <em>The genotype of individual 3 in the second generation would be heterozygous, </em><em>AS</em>.
The cross between the the heterozygous normal father and the sickler mother can only produce one of heterozygous normal individuals or sickle cell diseased individuals. Hence, individual 3 has to be heterozygous since he appeared phenotypically normal in the pedigree.
Answer:
No, light dependent reaction does not depend on Calvin cycle.
Explanation:
Calvin cycle occurs in the second phase of photosynthesis i. e. light independent reaction. In this process, carbondioxide fixation takes place in the leaves of the plant. Light dependent reaction occurs first in which ATP and NADPH are produced which are used in Calvin cycle of light independent reaction for the production of sugar molecule such as glucose. So light dependent reaction does not depend on Calvin cycle.
