B. Solve the following problems in non-Mendelian inheritance using the Punnett 1. Butterflies come in different colors. Some of them exhibit incomplete dominance. The three colors that show this trait are dark blue (B), white (W), and light blue (BW). Find the following: a. Genotypic and phenotypic ratios when a dark blue butterfly is crossed with a light blue butterfly square. b. Genotypic and phenotypic ratios of the F, generation when dark blue and white butterflies are crossed

In horses, assume that there are three colors affecting genes with the following effects: AA is lethal, Aa is white (albino), and aa allows color. B_ is black and bb is chestnut. D_ is solid and dd has white spots on color. (Albino would not show spots). A stallion that is heterozygous for all three genes and a mare of genotype AaBbdd are mated.a. What color is the mare and what are the genotypes of the gametes she produces?b. What is the color of the stallion and what are the genotypes of the gametes he produces?c. Construct a Punnett square and determine the frequencies of phenotypes that would be expected in the LIVE offspring.
3) In the snail Capaea nemoralis, an autosomal allele causing a banded shell (B®) is recessive to the allele for an unbanded shell (B°). Genes at a different locus determine the background color of the shell; here yellow (C') is recessive to brown (CBw). A banded, yellow snail is crossed with a homozygous brown, unbanded snail. The F1 are then crossed with banded, yellow snails (a test cross). a. What will the results of the testcross be in the loci that control banding and color ARE linked with NO crossing over.
Mendel's Eggs Predict the Inheritance Patterns of the offspring by observing the parent's Egg color. dominant to Pink (p).

At a different gene locus, the allele for hitchhikers thumb (D) is dominant to the allele for non-hitchhikers thumb (d).

Mendel's law of independent assortment states that the alleles of two (or more) different genes get sorted into gametes independently of one another. In other words, the allele a gamete receives for one gene does not influence the allele received for another gene. Assuming that during Metaphase 1 you have possibility 1 see picture below. Sketch possibility number 2 by using red and yellow color pencils. and upload possibility 2. Note: if you do not color pencils label them yellow and red. Possibility 1 Sketch Possibility 2 # Two equally probable arrangements of chromosomes at metaphase I
Assumptions: . 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? I

Mendel crossed a plant that was heterozygous for height and heterozygous for pea shape with a plant that was homozygous dominant for height and heterozygous for shape. What are the possible genotypes and phenotypes of the offspring? Dominant for height= T (tall) Recessive for height =t (short) Dominant for pea shape = R (round) pea %3D Recessive for pea shape =r(wrinkled) P1: Genotypes: Phenotypes: Genotypic Ratio: Phenotypic Ratio
