Why are the offspring flowers pink?
Incomplete dominance The F1-hybrid plants have a different phenotype (pink flowers) than either of the true-breeding parents. This is an example of incomplete dominance. When the F1-hybrid plants are self-fertilized, both parental phenotypes (red flowered plants and white flowered plants) reappear in the F2 generation.
What color flower is dominant?
Explore
| Trait | Dominant Expression | Recessive Expression |
|---|---|---|
| Color of seed albumen (Y) | Yellow | Green |
| Color of flower (P) | Purple | White |
| Form of ripe pods (I) | Inflated | Constricted |
| Color of unripe pods (G) | Green | Yellow |
What happens when you cross the offspring of a red and white flower?
Explanation: Incomplete dominance is an example of a non-mendelian trait (doesn’t follow the genetic rules established by Gregor Mendel). When two parents mate and produce offspring, the offspring is a blend of the two parents. So, a red flower and a white flower would make a pink flower.
When pink flowered plants were crossed they produced offspring with red pink and white flowers in a ratio of 1 2 1 This is an example of?
variegation
When pink-flowered plants were crossed they produced offspring with red, pink, and white flowers in a ratio of 1:2:1. This is an example of: a. variegation.
What is the genotype of white colored flower?
When ever the R gene is present in the genotype of a plant, the flower color is always red. The mutant form of this gene, which is recessive, is often written r. Plants with the genotype RR or Rr have red flowers. Plants with the genotype rr have white flowers.
What percentage of offspring will be red?
Alright, you know that the RR genotype gives red flowers. This happens in one combination, so 1/4 of the offspring will have red flowers.
How can two purple flowered parents produce white flowered offspring?
If Purple is dominant, then white is recessive. In order to have a plant with recessive traits it must be homozygous recessive; therefore, the plants will be white.
What is it called when red and white flowers make pink?
Incomplete dominance is when the phenotypes of the two parents blend together to create a new phenotype for their offspring. An example is a white flower and a red flower producing pink flowers. Codominance is when the two parent phenotypes are expressed together in the offspring.
How many of the offspring will be pink?
What percentage of offspring flowers are pink? The pink flower donates the r allele and produces pink flowers in 50% of the offspring.
