consider blue eyes (b) in humans to be recessive to brown eyes (B). Show the genotypes of a -eyed woman and a brown-eyed man whose mother had blue eyes. In a Punnett square show the genotypes of the expected offspring of the man and woman. Indicate the genotype ratio of the offspring. What percentage of the offspring should have blue eyes? (2 points) hat percentagoffspring of the other had blues (B). Show the offspring shound womano e in a pune...
The probability that brown-eyed parents, both with the recessive gene for blue, will have a child with brown eyes is 0.65. If such parents have 6 children, what is the probability that they will have (A) All blue-eyed children? (B) Exactly 5 children with brown eyes? (C) At least 5 children with brown eyes?
7) In humans, brown eyes (B) are a simple dominant trait over blue eyes (b). What is the genotype of a brown-eyed woman who has a blue-eyed child? A)bb -B)Bb С)ВВ D)BBB E) BbBb 8) The ability to roll the edges of the tongue upward in a U-shape is inherited as a dominant allele at a single gene locus, Which of the following genotypes would produce an individual that can roll their tongue?

i need this quick pls 3. A father with brown eyes marries a woman with blue eyes, and all of their children have brown eyes. (We are going to assume that this is a monogenetic trait, but in reality, t is not.) a. Assign symbols for the possible alleles. Brown:_ b. Which allele is dominant? Complete a Punnett square for the cross that results in all the offspring (the F1 generation) Blue having a brown-eyed phenotype C. What are the...
are recessive. A blue-eyed, left-handed 2. Blue eyes (b) and left-handedness (h) are recessive. A blue-eyed, len woman marries a brown-eyed, right-handed man who is heterozygous to both traits. Work the problem to answer the question below. Genotypes: b b hhxBb H h woman man Gametes: 0000 0000 What is the probability of their having a blue-eyed, left-handed child
I need c and d 13. Genetics. Hereditary characteristics are determined by pairs of genes. A gene pair for a particular characteristic is transmitted from parents to offspring by choosing one gene at random from the mother's pair, and, independently, one at random from the father's Each gene may have several forms, or alleles. For example, human beings have an allele (B) for brown eyes, and an allele (b) for blue eyes. A person with allele pair BB has brown...
also draw the punnet square 6. A brown-eyed man, whose mother was blue-eyed, marries a blue-eyed woman. The man is red-green colour blind and his wife has normal colour vision although her father was also colour blind. (Note: brown eyes is dominant over blue eyes and eye colour is inherited autosomally. Red-green colour blindness is a sex-linked recessive trait). a) What are the genotypes of the man and his wife with respect to these two traits? Ger b) Complete the...

1.My wife has black color eyes, the dominant trait. All of her family and relatives have dark eyes too. I have light color eyes (blue), the recessive trait. We are hoping for a blue-eyed baby. What is the probability we will have a baby with blue eyes? What is the probability we will have a baby with dark eyes? 2. In humans, tongue rolling is a dominant trait, those with the recessive condition cannot roll their tongues. Bob can roll...
8. Dihybrid Genetics: In humans, Brown hair (R) is dominant while red hair (r) is recessive. Freckles (6) is dominant while no freckles (f) is recessive. % Harry Potter is homozygous dominant for freckles and heterozygous for red hair. What is his genotype? What is his phenotype? What gametes could he produce? Ginny Weasley is heterozygous for freckles and has red hair. What is her genotype? What is her phenotype? What gametes could she produce? What is the chance that...
