The genotypes and phenotypes that result from the cross of Aa and Aa (A = normal pigmentation and a = albinism) are O phenotypes-3 normal: 1 albino; genotypes-1 homozygous dominant: 2 heterozygous: 1 homozygous recessive. O phenotypes-50% normal and 50% albino; genotypes-all homozygous recessive. O phenotypes-1 normal: 1 albino; genotypes-1 homozygous recessive: 1 homozygous dominant. O phenotypes-1 normal: 3 albino; genotypes-1 homozygous dominant: 2 heterozygous: 1 homozygous recessive. O pon e of the answer choices are correct

Sickle cell anemia is an inheritable red blood cell disorder that results in sickle-shaped red blood cells. The sickle-shaped red blood cells can stick to blood vessel walls and cause a blockage or slow the movement of blood throughout the body.   Individuals who are heterozygous produce both normal and sickle-shaped red blood cells which gives them resistance to malaria but they do not develop sickle cell anemia (so heterozygotes are unaffected on the pedigree).Let HbS be the allele for sickle cell anemia and let HbA be the allele for normal red blood cells.   Which of the following rows provides the correct genotypes for individuals I-2, I-4, II-1, and III-1? Select one: a. I-2 I-4 II-1 III-1 HbA_ HbAHbS HbAHbS HbA_ b. I-2 I-4 II-1 III-1 HbA_  HbAHbS HbAHbS HbAHbS c. I-2 I-4 II-1 III-1 HbAHbS HbAHbS HbAHbS HbAHbS d. I-2 I-4 II-1 III-1 HbAHbA HbAHbA HbAHbA HbAHbA

Four children have the following blood types: A, B, AB, and O. Could these children have the same two biological parents?

Could someone please help me with this grade 11 bio dihybrid cross problem in detail and how to solve this question, using a strategy? Assume that curly hair (C) is dominant to straight hair. Albinism (P ) is recessive to normal skin pigmentation. A woman who is heterozygous for curly hair and albinism has a child. The father is homozygous dominant for curly hair and has albinism. (a) Determine the possible phenotypes for their child. (double-crossing, Puneet square)(b) Calculate the four different probabilities of a child beingboth a male and of each phenotype.(c) What is the probability that the child will expressalbinism and have curly hair like his father?
