Question
Genotype refers to the letters used as symbols for the genes.
Let’s practice assigning letters for the tall and short phenotype. Remember, we usually use the letter of the dominant (trait).

- Which of the following is true? Question 10 options: a) A person's phenotype is a trait that is the result of the environment only. b) A person's phenotype is a trait that is the result of genes only. c) A person's phenotype is a trait that is the result of genes and the environment. d) A person's genotype is a trait that is the result of genes and the environment.arrow_forwardParents often want to know what is genetically possible for their children. If two parents are carriers for a recessive lethal trait, what are the odds that their child is also a carrier? Many times there is interest in tracking multiple traits at once (not just 1 or 2). The same probability rules apply here, you just multiple all the odds together at once. Imagine two parents. They are both carriers for red hair, one person is blood type AB, the other is type O. They want to know the odds of a daughter with red hair and type B blood. Please do no not do a giant Punnett square! Use probability or individual squares. a. What are the genotypes of the parents? b. What are the odds of each trait (daughter, red hair, type B)arrow_forwardPLEASE DO BAR GRAPHS BASED ON DATA: Procedure: Assuming both parents carry three tall genes and three short genes, you will model the inheritance of height for ten different offspring. Flip a coin six times to determine how many tall and short genes the child inherits. Heads represents a tall gene and tails represents a short gene. Record all of your data along with the class data in the tables below Data: Table 1: Group results Flip (Your Group) 1 2 3 4 5 Number of tails 0 1 2 3 4 Number of heads 6 5 4 3 2 Table 1: continued Flip (Your Group) 6 7 8 9 10 Number of tails 5 6 3 2 1 Number of heads 1 0 3 4 5 Table 2: Group and class results Flip Situation 0 T 6 H 1 T 5 H 2 T 4 H 3 T 3 H 4 T 2 H 5 T 1 H 6 T 0 H Your Group Total 1 3 6 10 9 5 1 Class Total 0…arrow_forward
- A gene has two alleles, E and e. Another gene also has two alleles, T and t. Which of the following correctly shows linkage between the two genes? Group of answer choices ET/et Te/Et Ete/T Ee/tTarrow_forwardAssumptions: . If the parent expresses the trait, they are homozygous dominant If the child/children express the trait but the parents do not, the parents are heterozygous. Traits selected: Brown Hair/Eyes And Widows Peak Write the Letters you will be using n the Punnet square for each trait: _Ww Bb_and_ww Bb_ Father Genotype: WW Bb Mother Genotype: ww Bb Parent Gametes possible gametes: possible gametes: Do you have the phenotype of either of the traits in the cross? If you do, which one? Are there any other offspring with either trait? Which trait? Which phenotypic probability did you fall into? Which phenotypic probability did other offspring fall into? Iarrow_forwardIn human beings, the gene for red‑green colorblindness (r) is sex‑linked and recessive to its allele for normal vision (R), while the gene for freckles (F) is autosomal and dominant over its allele for nonfreckled (f). A nonfreckled, normal‑visioned woman whose father was freckled and colorblind, marries a freckled, colorblind man whose mother was nonfreckled. What is the probability that the first child born to the couple will either be a freckled, colorblind boy or a non‑freckled, normal visioned girl or a non-freckled, normal visioned boy? What is the probability that the first four children born to the couple will be freckled and normal visioned girls?arrow_forward
- According to Amar J. S. Klar, is there a such thing as “left handedness”? What is the preferred term? Describe how the genetics works, according to his hypothesis. What are the alleles, and which combinations of alleles make for which type of hand use?arrow_forwardWhat’s the probability of receiving a particular gene? The Punnett Square is a tool that allows you to see the different gene combinations that are possible when two parents of any species create offspring.arrow_forwardMatch each formatting of "white" to what it represents in genetics. options: white WHITE (all capital letters) white (in italics) 1. phenotype 2. gene 3. proteinarrow_forward
- Please help to fill in the table based on the chart located to the right.arrow_forwardIf a B is a dominant allele that codes for a trait where the bearer of this allele has a black coat, and b is a recessive allele where the bearer has a brown coat, the recessive genotype will exhibit the phenotype of brown coat, the genotype will have the black coat phenotype, and the dominant genotype will have the black coat phenotype. (Use either heterozygous or homozygous in the blanks.)arrow_forwardSire Sire Parent B - First allele Sire B Parent B - Second allele b Now we take each allele from each parent and distribute it into the boxes in the appropriate row or column it borders, until each box has one gene pair - a color gene from parent A and a color gene from parent B. The completed square should look like this: Parent B - First allele B Dam Parent A - first allele Parent A - Second allele B Parent B - Second allele b Dam Parent A - first allele B BB Bb Parent A - Second allele b Bb bb This square now demonstrates the possible genotypes of the offspring if two hybrid parents mated. This table also demonstrates the likelihood of the offspring having that genotype. What are the genotypes and the likelihood (% chance) that each would be passed to offspring of these parents?
