Color in snapdragons is of equal influence (Incomplete Dominance). Cross a red with a white and give the phenotypic ratios. Cross two pink and find the ratios.

Homework Answers

Answer #1

Incomplete dominance is when the dominant allele (R) responsible for red colour of the flower does not able to completely suppress the character of the recessive allele (r) express white colour, as a result of this a new combination is produced with pink colour (Rr).

Many types of snapdragons show incomplete dominance with reference to flower color. If a pure breeding line of red snapdragons is crossed with a pure breeding line of white snapdragons, the offspring will all be pink in color. A.

In snapdragons, two genes control flower color, which can be red, pink, or white. Gene A encodes an enzyme that makes a precursor to red pigment, and gene R encodes the enzyme that makes the red pigment from the precursor. This makes Gene A epistatic to Gene R (if there is no precursor made, there can be no red pigment). Allele A (pigmented) is completely dominant to a (no pigment, white), and R isincompletely dominant to r. What would be...

Tallness (T ) in snapdragons is dominant to dwarfism (t ), while red (R ) flower color is incompletely dominant to white (R' ). The heterozygous condition results in pink (RR' ) flower color. The genes for these traits occur on separate chromosomes. A dwarf, red snapdragon is crossed with a plant homozygous for tallness and white fowers. a) Determine the genotypes of the parents. b) Determine all the types of gametes each parent can produce. c) Complete the Punnett...

In snapdragons, the plant height gene and the flower color genes are located on different chromosomes. Tall (T) is dominant to dwarf (t). Red flowers (FR) are incompletely dominant to white (FW), with the hybrid being pink. A homozygous tall-white is crossed to a homozygous dwarf-red,. The F1 plants are then self-fertilized to produce an F2 generation. a. What is the genotype and phenotype of the F1? b. What proportion of the F2 will have pink flowers? c. What proportion...

A population of plants displaying incomplete dominance for flower color (determined by one gene with only two alleles) has 60 individuals with red flowers (RR), 20 individuals with pink flowers (Rr), and 20 plants with white flowers (rr). What would you expect the phenotypic ratios to be in the future assuming the population is allowed to move to Hardy-Weinberg equilibrium? (show your work). The population of deer is currently 2,000 individuals. The population can be described by a logistic model...

Please show WORK! In some horses, coat color is autosomal and exhibits incomplete dominance, with palamino coloration intermediate to both chestnut and cremello coloration. Horses can also exhibit an immunodeficiency syndrome inherited as an X-linked recessive allele. You are a horse breeder, and cross a palamino female carrier for immunodeficiency syndrome with a normal, cremello male. 1. Use appropriate genetic notation to describe genotypes of the cross. 2. If you conducted this cross many times, what would be the expected...
