Practice Setting up the Punnett Squares: In dogs, short hair (H) is dominant to long hair (h). Complete the Punnett Square cross to show the combinations of a heterozygous mom and a heterozygous dad could create. EGG Identify the Dominant trait: What letter represents the dominant trait: Identify the Recessive trait: What letter represents the recessive trait: After you complete the Punnett Square cross, answer: What percentage of the dogs will likely have long hair? What is the phenotypic ratio of short hair to long hair? Short hair: long hair SPERM

Indicate the nature of the trait and type of inheritance involved in each of the following situations. (a) Children who exhibit this trait have at least one parent who exhibits the same trait. (b) Children exhibit this trait even though neither parent does. (c) The trait is expressed more commonly in sons than indaughters. (d) Tongue-rolling is expressed equally in both daughters and sons.
A is a dominant gene for normal pigment, and a is its recessive allele for albinism (and pink eyes). B is a dominant gene for brown eyes, and b is its recessive allele (blue). What is the mother's genotype if two brown-eyed parents have fraternal twins, one with blue eyes and one with pink eyes (albino)? a. AaBb b. AaBB c. aaBb d. aabb e. AABB
Like brown eyes, presence of dimples and cleft chin are dominant traits. Sarah has brown eyes and dimples, but no cleft chin. Her father has blue eyes but no dimples. She just married James who has blue eyes, dimples, and cleft chin. His mother has no cleft chin and his father has no dimples. What is the probability that Sarah and James will have a baby girl with blue eyes and dimples? What is the probability that they will have a baby boy with brown eyes and cleft chin?
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?
What will thr possible offspring from a dad who is heterozygous for freckles and a mom who is homozygous recessive for the freckles trait? Having freckles is the dominant trait while no freckles is recessive. Include Punnett square, genotypic and phenotypic ratios.
Hypothetically speaking, of course, right handedness is dominant to left handedness and brown eyes are dominant to blue eyes. Bob is a Dad. Bob has blue eyes and is right handed. His wife Barb has brown eyes and is also right handed. Their daughter Jenny has blue eyes and is left handed. What is everyone’s genotype?
Define and explain the relationship between genotypes and phenotypes (50 words) and dominant and recessive traits (50 words).
The gene for eye color has several alleles. The allele for brown eyes is symbolized with B and the allele for blue eyes is symbolized with b. A father has the phenotype of blue eyes (recessive trait) and a mother has a phenotype of brown eyes (dominant trait.). If they have a child, what is the most likely genotype? Bb bb BB none of these
Define blending inheritance and contrast it with preformationism.
Imagine that you are a doctor in a maternity ward. During your last shift, 20 babies were born. 10 had blue eyes, and 10 had brown eyes. Remember genotypes are the two alleles given for each trait, written with a letter. For this activity B =brown eyes b= blue eyes. Phenotypes are the physical appearance of the trait. Considering the possible genotypes you listed in question 3, what traits would the parents of brown-eyed and blue-eyed children have to have?
Describe the two possible versions of the traits for all of the characteristics you found in Pod shape, Pod color, Pea shape, Pea color, Flower color, Position of the flower. Give the ratio of the traits in the F2 generation for each (Mendel actual ratio). List the trait that was considered dominant first and the recessive trait second, for each pair of traits. Show the shorthand code for each trait. See the example below for plant height to see an example of how you can write your answer. Make sure your answer includes all six of the other historical ratios besides plant height. Example: Plant Height = 3 Tall (T) for every 1 short (t) plant = 3 T:1 t (Note: more precisely, Mendel’s result was 2.84 T:1 t).
Define quantitative trait locus.
