Could someone please help me with this grade 11 bio dihybrid cross problem on how to solve this question, using a strategy in detail! 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, Punnet square) (how to display the traits) (b) Calculate the four different probabilities of a child beingboth a male and of each phenotype. (steps in solving this) (c) What is the probability that the child will expressalbinism and have curly hair like his father? (steps in solving this)

Clara has polydactyly, an autosomal dominant that is 80% penetrant. Clara inherited her polydactyly from her mother, her father had no polydactyly in his family. She has an extra toe on her left foot. Her husband Ralph has no polydactyly in his family. A) What is the chance that Clara will have a child that will inherit polydactyly? B) What is the chance that the child will express polydactyly. You can leave these as un-calculated equations.

a) A woman has a rare abnormality of the eyes called ptosis, which makes it impossible for her to open her eyes completely. The condition has been found to be caused by a single dominant autosomal gene (P). Her father has ptosis, but not her mother. Her father's mother had normal eyelids.   What are the genotypes of the woman, her father, and her mother?  If this woman marries a man who is a normal individual for this eyelid condition what will be the phenotypic and genotypic ratio of their offspring?     b) Draw a small pedigree, noting sex of each individual as well as whether or not they are affected with ptosis.

If a girl has ptosis and then she marries a man who is a normal eyes, what will be the phenotypic and genotypic ratio of their offspring?   2) Create a small pedigree, noting sex of each individual as well as whether or not they are affected with ptosis

Consider a couple: a woman who is homozygous for a recessive mutation that causes X-linked colorblindness, and a man with full color vision (he does not carry a copy of the mutation).   a) What is the probability that a son of this couple will be colorblind? b) What is the probability that a daughter of the couple will be colorblind?

Freckles is determined by a single gene and having freckles is dominant over not having freckles. If a man with freckles and a woman without freckles have a child that does not have freckles then a)the man is heterozygous for the freckles gene. b)the child is heterozygous for the freckles gene. c)the woman and man are both heterozygous for the freckles gene. d) the woman is heterozygous for the freckles gen
