# mouse genetics 2 traits gizmo answer key

**What are the genotypes of the offspring gizmo?** – What are the genotypes of the offspring? The genotypes of the offspring are Ff Ee, ff EE, ff Ee, Ff EE. Analyze: The probability of an event is the likelihood that it will happen. Probability can be expressed as a percentage, such as 75%, as a decimal (0.75), or as a fraction (3/4).

**When traits are inherited what is the probability of each offspring’s genotype?** – Parents and Offspring By knowing the genotypes of the parents, we can predict the probability what the offspring’s genotype and phenotype will be. Essentially the key observation is that each of a parent’s alleles has the probability of 50% of being passed down to an offspring.

**How can a 4×4 square model the inheritance of two traits?** – Question: How can a 4×4 square model the inheritance of two traits? Model: Each parent mouse will contribute one allele for fur color and another for eye color. If a parent mouse is Ff Ee , there are four possible allele combinations the parent could pass to its offspring: FE , Fe , fE , and fe.

**What is the genotype of the black parent?** – Black is dominant, which means black individuals must have at least one B allele. Their genotype could be either BB or Bb.

**How do you build a DNA gizmo?** –

**Do you think most traits are inherited the way mouse fur color is?** – (BONUS) Do you think most traits are inherited the way mouse fur is, why? Yes, when the two traits from each parent are inherited the dominant trait always shows up even though a parent may have a recessive trait.

**How do you solve probability in genetics?** – One probability rule that’s very useful in genetics is the product rule, which states that the probability of two (or more) independent events occurring together can be calculated by multiplying the individual probabilities of the events.

**What is the probability that parents AaBb and AaBb will have offspring with genotype AaBb?** – Answer and Explanation: The correct answer: The probability of an aabb offspring when AaBb x AaBb parents are crossed is b. 1/16 . See full answer below.

**What is the probability that F2 offspring will be Aabbccdd?** – Answer and Explanation: The probabilities of the F2 offspring as what follows: 1. aabbccdd is 1/256 chance.

**How do you do a Punnett square with 2 traits?** –

**How do you solve Punnett Squares?** –

**How do you do a 4×4 Punnett square?** –

**Which trait is dominant and recessive?** – › biology › difference-between-domina…

**Which is dominant allele A or B?** – With eye color, for instance, “B” stands for a brown allele and “b” stands for a blue allele. An organism with two dominant alleles for a trait is said to have a homozygous dominant genotype. Using the eye color example, this genotype is written BB.

**What are the 3 types of genotypes?** – The different types of genotypes are- homozygous recessive (pp), homozygous dominant (PP), and heterozygous (Pp). The homozygous dominant and the heterozygous genotypes show the same phenotypes.
