Ans.
Albinism shows a genetic disorder, which is characterized by absence of coloration or pigmentation in individuals. It is an autosomal recessive disorder that transmits from parents to their offspring, when offspring receives both the mutated copies of gene responsible for albinism.
For a genetic disorder, dominant or wild type allele is represented by capital letter, such as 'A', while recessive or mutated allele is represented by small letter, 'a'. As 4th picture is representing male and female gametes with recessive alleles (a) , the resulting zygote will have both recessive alleles for albinism (aa), '4th zygote will develop into an albino child.'

Answer:
C. A-T rich; initiator
Explanation:
Replication origins have A-T rich DNA sequences that attract initiator proteins.
Replication origin is the DNA sequence where replication is initiated in a genome. The replication origin sequences is rich in adenine (A) and thymine (T) bases because it is easier to break the bonds between the bases compared to the bonds between guanine and cytosine. adenine (A) and thymine (T) bases have two bonds joining them as against three bonds between guanine and cytosine
The initiator proteins recognizes DNA sequences in the replication origin and helps to initiate DNA replication.
