What happens when a homozygous red and white flowers are crossed?
All (100\%) of the offspring from the cross of a homozygous red-flowered plant with a homozygous white-flowered plant will have red flowers.
When a red flowering plant crossed with a white?
Mirabilis, a homozygous plant with red flowers, if crossed with another homozygous plant with white flowers, produces pink-plowered progency.
When a pure pea plant with red flower is crossed with pure pea plant with white flower What will be the characteristics of offspring in first filial generation?
So, genotype of pure red flower is represented by RR while genotype of pure white flower is represented by rr. The offspring in the first filial generation are phenotypically red(RR) and genotypically both red and white(Rr). This can be verified from the Mendel’s first law also called law of dominance.
What will be the color of a flower resulting from the cross of a red and a white pea plant flowers?
In a cross between a red flowered plant and a white flowered plant, all offsprings produced bear pink flowers.
When a red flower RR and a white flower RR are crossed all of the offspring are pink this is an example of?
Incomplete dominance
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 happens when a red Coloured homozygous antirrhinum is crossed with a homozygous white Coloured plant work out the genotypes and phenotypes?
A homozygous red colored flower plant (RR) is crossed with homozygous white coloured flower plant (rr). If red flower is dominant over white flower, then the genotype and phenotype of their offspring is: Genotype – Rr, Phenotype – Pink. Genotype – RR, Phenotype – Red.
What does it mean when pea plants are described as true breeding?
Mendel’s Crosses The result is highly inbred, or “true-breeding,” pea plants. These are plants that always produce offspring that look like the parent. By experimenting with true-breeding pea plants, Mendel avoided the appearance of unexpected traits in offspring that might occur if the plants were not true breeding.
What is the genotype of a red flowered pea plant?
1. Starting with the pea plants, let’s say that the red flower-color allele is dominant and is denoted as R, and that the white flower-color allele is recessive and is denoted as r. You have one parent with genotype RR and the red phenotype. The other parent has genotype Rr, and the red phenotype.
When a red RR flowered plant is crossed with white WW flowered plant all the off spring of generation are pink it indicates that R gene is?
incomplete dominance
Correct Option – C incompletely dominant Explanation- The offsprings Rr are pink due to partial expression of both alleles i.e. incomplete dominance.
