To get the most pink flowers, a red and white rose plant must be mated. Red would have two red alleles–RR and white would have two white alleles–WW. In this cross, all of the offspring would inherit one red allele and one white allele-RW and would be 100 percent pink!
What cross do you perform to produce all red flowered plants?
The crossing of a red flowered plant and a white flowered plant, produces all the offspring with pink flowers.
What is the genotype of the pink flowers?
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.
What are the phenotypes in F2 generation when two pink flowers are crossed?
The phenotype in the F2 generation results in the same ratio as proposed by Mendel, i.e., 1:2:1. The offspring phenotypes were 25% red flowers, 25% white flowers, and 50% pink flowers.
What is the name of the flower that is pink?
Dianthus family (carnation, pink, and sweet william, and especially garden pink, whence the colour got its name) Flowering plum tree. Hibiscus. Hyacinth.
When red and white flowers are crossed pink flowers are produced?
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.
What crosses will result in all dominant phenotype?
In the test cross invented by Mendel, the plant with the dominant phenotype is crossed with a plant that is homozygous for the recessive trait. If the unknown is homozygous, all offspring will have the dominant phenotype.
What is the genotype of red rose?
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.
What is the genotype of the pink four o’clock flower?
Two hybrids would be the flowers that are pink; this also means they are heterozygous with the genotype “Rr”. If these two are crossed,…
Is PP genotype or phenotype?
There are three available genotypes, PP (homozygous dominant ), Pp (heterozygous), and pp (homozygous recessive). All three have different genotypes but the first two have the same phenotype (purple) as distinct from the third (white).
What is the F2 phenotypic ratio?
Expected genotype and phenotype ratios
The phenotypic ratio of the F2 offspring of the cross is 9:3:3:1, where 9/16 of the F2 individuals possess the dominant phenotype for both traits, and 1/16 are recessive for both traits. (
What is phenotypic ratio of F2 generation?
The normal phenotypic ratio in F2 generation is 3:1 and the genotypic ratio is 1:2:1.
What are the F1 and F2 generations?
F1 generation refers to the first filial generation of the offspring from the parents, while F2 generation is the second filial generation of the offspring, generated through inbreeding of F1 individuals.
Why are many flowers pink?
Many of the actual chemicals in flower petals that give them different colors are called anthocyanins. These are water-soluble compounds that belong to a bigger class of chemicals known as flavonoids. Anthocyanins are responsible for creating the colors blue, red, pink, and purple in flowers.
