Why are snapdragons pink?
A heterozygous Tt will produce a pink flower, and the homozygous tt results in a white flower. It is also important to note that the single allele trait displayed in the snapdragon is not dominant, which allows for the pink flower when a red (T) and a white (t) allele are present.
Why a cross between the red flowers snapdragon plants and the white flowers Snapdragon produced pink flowers?
Figure 21: A cross between a red and white snapdragon will yield 100% pink offspring. This pattern of inheritance is described as incomplete dominance, meaning that neither of the alleles is completely dominant over the other: both alleles can be seen at the same time.
Why heterozygous condition in antirrhinum produces pink flowers instead of red?
The two alleles are not expressed in a way to hide the effect of the other allele; instead, the phenotype is in between the two and intermediate. Thus, the heterozygote is one that produces flowers with a pink color.
What occurs when true-breeding white and red snapdragons are crossed and offspring have pink flowers?
In Snapdragon, a cross between true-breeding red flowered (RR) plants and true breeding white flowered (rr) plants showed a progeny of plants with all pink flowers. (a) The appearance of pink flowers is not known as blending.
What is the genotype of the pink Snapdragon?
The genotype for the pink flower is Rr and the genotype for the white flower is rr. This would lead to a 50% chance of the offspring having a phenotype of pink.
When the pink snapdragon is self pollinated what phenotypes were produced?
A genetic cross of inbred snapdragons with red flowers with inbred snapdragons with white flowers resulted in F1-hybrid offspring that all had pink flowers. When the F1 plants were self-pollinated, the resulting F2-generation plants had a phenotypic ratio of 1 red: 2 pink: 1 white.
When pink-flowered plants were crossed they produced red flowered pink-flowered and white flowered plants in a ratio of 1 2 1 This is an example of?
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 probability of getting a red snapdragon if a pink snapdragon is crossed to a white snapdragon?
Red and white in 3 : 1 ratio.
What is the probability of two pink flowers producing a red flower?
In this case, if two pink-flowered pea plants are mated ("crossed" is a better word than "mated" for plants), the offspring plants are independent of each other, and each has red flowers with probability 1/4, pink flowers with probability 1/2, and white flowers with probability 1/4.
When a cross was made between red flowered and pink flowered antirrhinum?
When a cross is made between two purebreds i.e dominant red flower-bearing plant with recessive white-bearing plant, all the progeny are hybrids i.e they all bear pink-colored flowers.
What is the difference between a heterozygous phenotype produced by incomplete dominance and a heterozygous phenotype produced by codominance?
What is the difference between a heterozygous phenotype produced by incomplete dominance and a heterozygous phenotype produced by codominance? In incomplete dominance, the heterozygous phenotype is somewhere between the two homozygous phenotypes. In codominance, the heterozygous phenotype shows both traits.
What are the two alleles from flower color in Snapdragon?
In snapdragons, flower color is controlled by incomplete dominance. The two alleles are red (R) and white (R'). The heterozygous genotype is expressed as pink.
Is Snapdragon pink flowered plants are produced when red flowered plants are crossed with white flowered plants this type of inheritance can best be described as?
Option b. is incorrect as pink flowering plants are produced in snapdragons when red flowering plants are mated with white flowering plants. If the red allele dominates over the whiter allele then it is said to be the law of complete dominance. ... Instead, the alleles are mixed to form a new different trait.
What phenomenon is shown by the production of pink flowers?
when a red flower and white flower produces a pink colour flower as its offspring the condition is known as incomplete dominance. usually a pink offspring is produced due to the the recombination of the the two genes one of which is the dominant gene and the other is the recessive gene.
Why genotype will produce pink plant?
Since the snapdragon is controlled by incomplete dominance, one allele for red (R), and one for white (W), would result in a pink flower. ... The genotype for the pink flower is RW, and the genotype for the white flower is WW. This would lead to a 50 percent chance of the offspring having a phenotype of pink.
