Genetics Question
Step by step
Solved in 3 steps
- If a mother with sickle-cell anemia and a father with the sickle-cell trait havechildren, calculate the percentages of each genotype and phenotype of the offspring from the Punnett square.Would it be possible for a woman with an uncleft chinto have children with cleft chins? Use a Punnett squareand one or more hypothetical genotypes for the father todemonstrate your point.Use a Punnet Square to answer the question below. If the dad is heterozygous for freckles and the mom is homozygous for no freckles, what is the probability that they will have children with freckles or no freckles?
- Use a punnett square to calculate the following: George is the youngest child in a family that includes 4 children. All of the children have the recessive phenotype-attached earlobes. However both parents have unattached earlobes, the dominant trait. Use the letters G, g and answer the following: What is the genotype of the mother? What is the genotype of the father? What percentage of the offspring would express the recessive trait?If someone with auburn hair has children with someone with red hair (but whose mother had black hair), what are the genotype and phenotype probabilities for their children?In 1-3 sentences each define the follwing terms: complex trait, concordance, environmental variance.
