A description of the pair of alleles in our DNA is called the genotype. Since there are three different alleles, there are a total of six different genotypes at the human ABO genetic locus. The different possible genotypes are AA, AO, BB, BO, AB, and OO. How are blood types related to the six genotypes?
What is genotype in Punnett Square?
▪ Genotype: The letters that make up the individual. E.g. TT or Tt. ▪ Phenotype: The physical characteristics of the particular trait. E.g. Tall or short. ▪ Dominant trait: Signified by capital letter-E.g. T.
What is a genotype and give an example?
An organism’s genotype is its specific combination of alleles for a given gene. So, for example, in the pea plants above, the possible genotypes for the flower-color gene were red-red, red-white, and white-white. The phenotype is the physical manifestation of an organism’s allellic combination (genotype).
What is the meaning of AA AS and SS genotype?
Blood genotype indicates of the type of protein (Haemoglobin) that is in the red blood cells. You could be Haemoglobin AA, AS, AC, SS or SC based on what is inherited from your parents. Individuals with blood genotype SC and SS are said to have sickle cell disease while AS is known as sickle cell trait.
Which answer is an example of a genotype?
The term just means “the genes a particular organism has.” Any example of a genotype would just be a chart of a particular living thing’s chromosomes, or DNA molecules responsible for various genetic traits.
What is ment by genotype?
A genotype is the genetic arrangement that makes up the traits that an organism inherited from its parents. Genotype can also mean the entire collection of genes an offspring inherited from its parents. … Human beings have around 20,000 genes in their DNA.
What is genotyping used for?
Genotyping determines differences in genetic complement by comparing a DNA sequence to that of another sample or a reference sequence. It identifies small variations in genetic sequence within populations, such as single-nucleotide polymorphisms (SNPs).
What is the sickness of AA genotype?
Children with genotype AA (92.3%) were more susceptible to malaria parasite than AS (5.1%) and SS (2.6%). The association of haemoglobin genotype with malaria was highly significant (p<0.001).
What does genotype GG mean?
An organism that has an identical pair of alleles for a trait is called homozygous. The true-breeding parents GG and gg are homozygous for the pod color gene. Organisms that have two different alleles for a gene are called heterozygous (Gg). … An organism’s genotype results in an organism’s phenotype.
What is a heterozygous genotype?
(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 are the genotypic and phenotypic of 2 purple flowers?
A pair of alleles—one from each parent—makes up the genotype for a trait. … In pea plants, purebred purple flowers have a genotype with two purple alleles, which produces a phenotype of purple petals. Purebred white flowers have a genotype of two white alleles, which displays the white phenotype.
What is the genotype of the male?
Male Genotype
When a sperm carrying the Y chromosome fertilizes an egg, the resulting embryo has a genotype of XY and will be a male. With rare exceptions, all other embryos will be XX or female. Although the Y chromosome codes for a male, the X chromosome is vital for normal human development.
What is the genotypic ratio?
