Answer: F stands for feather R stands for red and W stands for white.
What does F mean in genotype?
Each pair of alleles represents the genotype of a specific gene. For example, in sweet pea plants, the gene for flower color has two alleles. One allele codes for purple flowers and is represented by the uppercase letter F, whereas the second codes for white flowers and is represented by the lowercase letter f.
What does F stand for in chicken genotypes?
What are the offspring genotypes? F An organism’s appearance is its phenotype. Describe the offspring’s phenotype.
What are the letters in a genotype?
genotype = the genes of an organism; for one specific trait we use two letters to represent the genotype. A capital letter represents the dominant form of a gene (allele), and a lowercase letter is the abbreviation for the recessive form of the gene (allele).
What do genotypes tell you?
Genotype refers specifically to the genes, not the traits; that is, the raw information in an organism’s DNA. … The combination of the two, and which one is dominant, determines what trait the allele will express. Genotype simply means what alleles are carried in a particular organism’s DNA.
Why do genotypes have 2 letters?
The two letters in a genotype represent the pair of alleles. The uppercase letter represents the dominant allele and the lowercase letter represents recessive allele.
What are the 3 types of genotypes?
There are three types of genotypes: homozygous dominant, homozygous recessive, and hetrozygous.
What are the six genotypes for blood types?
The different possible genotypes are AA, AO, BB, BO, AB, and OO. How are blood types related to the six genotypes? A blood test is used to determine whether the A and/or B characteristics are present in a blood sample.
What is the white chickens genotype?
In some chickens, the gene for feather color is controlled by codominance. The allele for black is B and the allele for white is W. The heterozygous phenotype is known as erminette.
What are the possible genotypes of the offspring?
Predicting the genotype of offspring
There are four possible combinations of gametes for the AaBb parent. Half of the gametes get a dominant A and a dominant B allele; the other half of the gametes get a recessive a and a recessive b allele.
Is AA a genotype?
What is a Genotype? … There are four hemoglobin genotypes (hemoglobin pairs/formations) in humans: AA, AS, SS and AC (uncommon). SS and AC are the abnormal genotypes or the sickle cells. We all have a specific pair of these hemoglobin in our blood which we inherited from both parents.
Is blue eyes a genotype or phenotype?
Finally, the genotype of an organism with two recessive alleles is called homozygous recessive. In the eye color example, this genotype is written bb. Of these three genotypes, only bb, the homozygous recessive genotype, will produce a phenotype of blue eyes.
Which allele is always written first?
The alleles are represented by letters. The letter chosen is usually the first letter of the trait.
