Answer:
The correct answer would be B. thrombocytes.
Thrombocytes, also called platelets are the components of the blood which play important role in the process of hemostasis.
Hemostasis is the process of preventing the flow of blood from the damaged site or damaged blood vessel. It is the first stage involved in the healing of the wound.
Platelets form the platelet-plug at the site of damage which in turn activates another blood clotting factor fibrinogen.
Fibrinogen gets converted into an active fibrin (insoluble) which forms the meshwork like structure to trap more and more platelets and red blood cells. It results in the formation of a clot which completely seals the cut or damaged site.
Answer: The probability that individual 1 is heterozygous is 1.
The probability that individual 3 is heterozygous is 1.
The probability that individual 4 is affected is 0.
Explanation: Since the father was said to be affected, the genotype of the father will be homozygous recessive. Using (A) to represent the dominant allele and (a) to represent the recessive allele, we can say that the father's genotype is aa.
Since the genotype of the mother was not given, we assume that she has wild-type genotype which is homozygous dominant allele because no contrary information was given. We can then say that her genotype is AA.
A cross between aa and AA will produce offspring with genotype Aa only. Therefore, we can conclude that 1 - 4 have heterozygous alleles.
