• Crossing homozygous plants with differing characteristics

  31721 Crossing homozygous plants with differing characteristics I had to cross a homozygous dominant smooth, yellow seeded plant with a homozygous excessive wrinkled, green seeded plant, and this is what I came up with: A.

• % of traits passed to progeny

  it's your standard Aa X Aa cross, which gives the genotypes: AA - 25% (homozygous dominant - dominant phenotype, i.e. all smooth peas) Aa - 50% (heterozygous - dominant phenotype, i.e. all smooth peas) aa - 25% (homozygous recessive - recessive phenotype

• Genetics problem set

  To determine if an F2 seed is heterozygous or homozygous for a dominant phenotype cross it to a recessive plant. If the seed is homozygous only plants with dominant traits are produce.

• Genotypic and phenotypic ratios in hair texture in dogs.

  Suppose WW - Homozygous wire, Ww - heterozygous wire, ww - Homozygous smooth Ww x Ww - 1WW: 2Ww: 1ww Test cross - Ww x ww - 2Ww: 2ww - ½ wired: ½ smooth

• Punnett square to predict what the offspring will look like

  In guinea pigs, black coat color (A) is dominant over white (a), short hair (B) is dominant over long (b), and rough coat (D) is dominant over smooth (d).

• Dihybrid Cross Genotype

  Solution: 24382: Dihybrid cross When the homozygous dominant genotype has the same phenotype as the heterozygous genotype a test cross is performed to distinguish between them.

• Chromosome mapping and coefficient of coincidence

  134374 Chromosome Mapping Assume that investigators crossed a strain of flies carrying the dominant eye mutation Lobe on the second chromosome with a strain homozygous for the second chromosome recessive mutations smooth abdomen and straw body.

• Cells & Plant Seed Characteristics

  Therefore, TTRR is a homozygous tall/round plant. Likewise, ttrr would be a homozygous recessive short/wrinkled plant. If we cross TTRR with ttrr, we need to find out the types of gametes produced by each plant.

• Discussion of probability and explanation of dihybrid cross

  For example, we can ask; what is the probability of getting a purple smooth corn seed from a dihybrid F1 cross of PpSs? Question is: is purple dominant or recessive? So does pp = purple, or does PP?
