Consider the production of flower color in the Japanese morning glory (Pharbitis nil). Dominant allelesof either of two separate genes (A_bb or aaB_) produce purple petals, A_B_ produces blue petals, andhomozygous recessives for both genes produce scarlet petals.

In guinea pigs, short hair is dominant to long hair. Also in guinea pigs, black eyes aredominant to red eyes. A male guinea pig that is heterozygous for both traits is crossedwith a female that is long haired and red eyed. What are the expected phenotypes oftheir offspring? Provide the phenotypic ratio as well.
In guinea pigs, the black coat (B) is dominant over the white coat (b), and straight hair (H) is dominant over curly hair (h). Using a Punnett square, complete the cross between a heterozygous black, curly-haired individual and a homozygous straight-haired, white individual. State the parent genotypes and gametes, and the F1 phenotypes and genotypes.

Mendel crossed two Pea plants for plant height and flower color Tall plant (T) is dominant to Short Plant (t). Purple Flower (P) is dominant to white flower (p). Using the following information perform the dihybrid cross using punnett squares that will predict all possible genotypes of the offspring and list the number and description of the phenotypes of the offspring. A. One plant homozygous dominant for plant height and flower color crossed with another plant homozygous recessive for plant height and heterozygous for flower color.
Red eyes is the wild-type phenotype in Drosophila, and severaldifferent genes (with each gene existing in two or more alleles) affect eye color. One allele causes purple eyes, and a different allelecauses vermilion eyes. The purple and vermilion alleles are recessive to red eye color. Two types of crosses provided thefollowing data:Cross 1: Males with vermilion eyes × females with purple eyes354 offspring, all with red eyesCross 2: Males with purple eyes × females with vermilion eyes212 male offspring with vermilion eyes221 female offspring with red eyesExplain the pattern of inheritance based on these results. Whatadditional crosses might you make to confirm your hypothesis?
In the progeny of controlled crosses,recognize phenotypic ratios diagnostic ofsingle-gene inheritance (1:1 in haploids, and3 :1, 1 : 2 :1, and 1:1 in diploids).
Consider these two crosses and assume that independent segregation is exhibited by all gene pairs: RrmmTT x RRMmTtFfGg x FfGg Derive the gametic ratio of the second parent in each cross using the branching method. What proportion of the offspring in each cross will be heterozygous for all gene pairs? Derive the genotypic ratio for the offspring from each cross using the branching method. Show complete solutions.
A common houseplant called a pothos sometimes have streaks of yellow on their green leaves. Assuming this is caused by codominance where the leaves of the plant can be green yellow (GY). What are the genotypic and phenotypic ratios that would result from a cross between two heterozygous plants?

Purple (P) flower color is dominant to white (p) flower color. Cross two heterozygous parents using a Punnett square. What are the genotypes and phenotypes of the resulting offspring? Express the results as ratios.
Mendelian ratios are modified in crosses involving autotetraploids.Assume that one plant expresses the dominant trait greenseeds and is homozygous (WWWW). This plant is crossed to onewith white seeds that is also homozygous (wwww). If only onedominant allele is sufficient to produce green seeds, predict theF1 and F2 results of such a cross. Assume that synapsis betweenchromosome pairs is random during meiosis.
Consider this cross in pea plants: Tt Rr yy Aa × Tt rr Yy Aa, whereT = tall, t = dwarf, R = round, r = wrinkled, Y = yellow, y = green,A = axial, a = terminal. What is the expected phenotypic outcomeof this cross? Have one group of students solve this problem bymaking one big Punnett square, and have another group solve it bymaking four single-gene Punnett squares and using the multiplication method. Time each other to see who gets done first.
