In humans, having freckles is dominant to not having freckles. What is the
Step by step
Solved in 2 steps
- In humans, having freckles is dominant to not having freckles. What is the phenotype of a homozygous dominant?In humans, having freckles is dominant to not having freckles. What are the possible genotypes with someone with freckles?Albinism is a recessive trait. Two individuals who both have normal pigmentation have one child out of three who has albinism (without melanin pigmentation). What are the genotypes of this child's parents?
- For a recessive condition, two normal heterozygous individuals have children. What is the likelihood of their children being affected by this condition? What is the likelihood of their children being carriers without the condition? What is the likelihood of their asymptomatic children being carriers? Suppose that an individual with the condition has children with a heterozygous individual, what is the likelihood of their children being carriers?In humans, having freckles is dominant to not having freckles. What is the genotype of a person without freckles?Many animals and plants bear recessive alleles for albinism, a condition in which homozygous individuals lack certain pigments. An albino plant, for example, lacks chlorophy and is white, and an albino human lacks melanin. Examples of humans with albinism include blues musicians, and brothers, Johnny and Edgar Winter. Neither one of their parents is albino. What is the genotype of Johnny and Edgar's mother? What is the genotype of Johnny and Edgar's father? What proportion of the children born to Johnny and Edgar's parents would you expect to be albino? (Draw a Punnett Square to solve this.) DIGATALLY EMASTERED O Mother Aa. Father Aa, 25% of their children are expected to bc albino O Mother AA, Father AA, 25% of their children arc expected to be albino O Mother aa, Father aa. 100% of their children are expected to be albino Mother Aa, Father aa, 50% of their children are expected to be albino
- Both red/green color blindness (R=normal, r=colorblind) and Duchenne-type muscular dystrophy (D=normal, d=muscular dystrophy) are X-linked recessive traits that map close to each other. A woman has a father who is red/green color blind. Her mother's family has a history of Duchenne's muscular dystrophy. This woman is apparently healthy with neither color blindness nor muscular dystrophy. She marries a healthy man and they have four sons and two daughters. Half the sons are healthy but color blind, the other half have normal color vision, but have Duchenne's muscular dystrophy. The daughters are both normal. What is the genotype of the woman? ** The notation is written as X/X (so the / separates the two X chromosomes in a female) Group of answer choices RD/rd rd/rd Rd/rD RD/RDIn humans, brown eyes are dominant to blue eyes, and the ability to roll your tongue is dominant to not being able to roll your tongue. If a mother who was heterozygous for eye colour and homozygous recessive for tongue rolling had a baby with a father that was heterozygous for both traits, what is the probability that their child would have blue eyes and could roll their tongue?Purple Hair is dominant. Blue hair is recessive. One parent is heterozygous; the other parent has blue hair. A.) What is the probability of them having a blue-haired child?
- A woman homozygous dominant for albinism marries a man who is homozygous recessive for albinism. What are the possible genotypes and phenotypes percentages for their offspring?In a cross between fair skin, black hair (heterozygous for all these traits) with brown skin, red hair, which of the traits is/are dominant and which is/are recessive?Hair texture is determined by gene c in an incomplete dominance inheritance pattern, where the heterozygous condition (c1c2) results in wavy hair. Hairline is controlled by gene H, where a widow's peak is dominant to a straight hairline. If a woman with curly hair and a straight hairline has a child with a man with a widow's peak and straight hair (his mom had a straight hairline), what is the chance they would have a kid that has exactly the same hair as mom? Draw the Punnett square and demonstrate the possible genotypes and phenotypes that could result from these two parents' mating.
