In a plant, gene ‘A’ is responsible for tallness and its recessive allele ‘a’ for dwarfness. ‘B’ is responsible for red flower colour and it’s recessive allele ‘b’ for white flower colour. A tall and red flowered plant with genotype (AaBb) is crossed with dwarf and red flowered plant (aaBb).
What is the genotype of a red snapdragon?
We are told that the genotype of red snapdragons is CR CR. The C means color and the R means red. Remember, the set of alleles an organism possesses for a characteristic is their genotype.
What is the genotype for red flowers?
Plants with the genotype RR or Rr have red flowers.
What is the genotype of a white snapdragon?
In snapdragons, the color of the flower is controlled by incomplete dominance. The two alleles are red (R) and white (W). … 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.
What is the genotype of flower?
Each plant’s genotype contributes to its phenotype, which, in this case, is the outward appearance of its flowers. A particular genotype is described as homozygous if it features two identical alleles and as heterozygous if the two alleles differ. The process of determining a genotype is called genotyping.
What is the allele for a red Snapdragon?
In snapdragons, flower color is controlled by incomplete dominance. The allele for red is Rand the allele for white is W.
What are the genotypes of the pink red and white flowering plants?
3. Now let’s say that R and r are codominant. The Rr genotype results in a pink flower-color. Out of four offspring, how many will have pink flowers.
Is red flower a genotype or phenotype?
Answer and Explanation: The genotype of the flowers is the combination of alleles they get. The red flower has a heterozygous genotype because it gets one dominant allele, represented by a capital letter, and one recessive allele, represented by a lower case letter.
What is genotype example?
A gene encodes eye color. … If the child inherits two different alleles (heterozygous) then they will have brown eyes. For the child to have blue eyes, they must be homozygous for the blue eye allele.
What is red rose genotype?
Lastly, you know that the Rr genotype results in pink flowers. This happens in two combinations, therefore 1/2 of the offspring have pink flowers. This means that among four offspring, on average, 1 has red flowers, two have pink flowers, and one has white flowers.
What is genotype for black chickens?
The black color is represented by allele B and white color by allele W , as neither of these allele can dominate over the other. On mating a black chicken with white chicken, the offsprings will inherit B allele from black parent and W allele from white parent. The genotype of offsprings will be BW.
What are the heterozygous genotypes?
(HEH-teh-roh-ZY-gus JEE-noh-tipe) The presence of two different alleles at a particular gene locus. A heterozygous genotype may include one normal allele and one mutated allele or two different mutated alleles (compound heterozygote).
What would the heterozygous genotype be of a flower that is white and red if these traits were said to have incomplete dominance?
In snapdragons, flower color is controlled by incomplete dominance. The two alleles are Red (R) and White (W). … The two alleles are Red (R) and White (W). The heterozygous genotype is expressed as pink.
What is genotype AA?
The term “homozygous” is used to describe the pairs “AA” and “aa” because the alleles in the pair are the same, i.e. both dominant or both recessive. In contrast, the term “heterozygous” is used to describe the allelic pair, “Aa”.
What is my genotype?
In a nutshell: your genotype is your complete heritable genetic identity; the sum total of genes transmitted from parent to offspring. There are four hemoglobin genotypes (hemoglobin pairs/formations) in humans: AA, AS, SS and AC (uncommon).
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.
