- Problem 3: In snapdragons, the inheritance of flower color and size of leaves are examples of Incomplete Dominance. When red flowered plants are crossed with white, the offspring have pink flowers. Similarly, when a plant with broad leaves is crossed with plants having narrow leaves, the offspring have intermediate leaves. Regarding a cross between a homozygous red-flowered, broad- leaved plant with a homozygous white-flowered, narrow-leaved plant. What are the phenotypes and their ratio in the F1 generation? Construct a Punnett square. What are the phenotypes and their ratio in the F2 generation? Construct a Punnett square.Dihybrid Cross Problem 1: Predicting combinations of alleles in gametes of plants heterozygous for two traits. A pea plant is heterozygous for both seed shape and seed color. S is the allele for the dominant, spherical shape characteristic; s is the allele for the recessive, dented shape characteristic. Y is the allele for the dominant, yellow color characteristic; y is the allele for the recessive, green color characteristic. What will be the distribution of these two alleles in this plant's gametes? A. 50% of gametes are Sy: 50% of gametes are sY B. 25% of gametes are SY; 25% of gametes are Sy: 25% of gametes are sY; 25% of gametes are sy. C. 50% of gametes are sy: 50% of gametes are SY D. 100% of the gametes are SsYy E. 50% of gametes are SsYy: 50% of gametes are SSYY.punnett square practice 1. Let's say that in seals, the gene for the length of the whiskers has two alleles. The dominant allele (W) codes long whiskers and the recessive allele (w) codes for short whiskers. a.

Two unlinked loci effect mouse hair color. AA or Aa mice are agouti. Mice with genotype aa are albino because all pigment production is blocked. regardless of the phenotype at the second locus.

Complete the Punnett square for a cross between a black chicken (BB) and a white chicken (WW). Give the phenotype of the offspring in the F1 generation. Кey BB – black ww- white F1 BW – checkered Phenotype:PROBLEM 3: Using the Punnett square, determine the different combination of gametes with the genotypes G9MM (paternal) and ggmm (maternal). G is dominant for having a widows peak and g is recessive for not having a widow's peak. M is dominant for having the ability to roll the tongque and m is recessive for not having the ability to roll the tongue. Determine the following: a. What are the offsprings phenotype: b. What are the offsprings genotype: c. Probability of widow's peak and can tongue roll d. Probability of offspring with no widow's peak but can roll its tonque e. PUNNETT SQUAREBackground Problem N° 6 Objective: To illustrate the differences between the dominant/recessive model vs. partial (or incomplete) dominance model. In incomplete dominance, the phenotype is neither dominant nor recessive, but intermediate instead. a. Explain why a monohybrid cross of snapdragon plants carrying white flowers with red-flowered plants produces all pink flowers in the F1 generation. [Hint: What makes flowers red, purple, yellow, etc.?] b. What are the genotypic and phenotypic ratios of snapdragon flowers in the F2 generation? True breeding individual = Homozygous for either trait.
