no. The ABO system and Rh blood group are already decided the moment sperm meets ovum. It is decided by the gene we have. For ABO classification, to put it simply people with A blood type has two A gene or one A gene plus one O gene. People with B type have two B gene or one B gene plus one O gene. People with AB type has one A gene and one B gene. O type has two O genes. A father passes one of his blood gene to his child and a mother passes one as well that the child now has two, and the combination is what decides the child's blood type. Bombay type is a very rare blood type different from A, B, or O. You can only have it if your family has a very rare gene, or in other words, if one of your family has it.
a spelling
A gene is a section of DNA within the chromosome.
capital letter
Genotype versus Phenotype Genotype is your specific gene for a certain Trait. lets say B was for Tall gene and b is for small gene. your Genotype to Tall could be BB or Bb your gentype for small will be bb. Phenotype is what is the physical Appearance evne though the Genotpe has one gene that codes for big and one that codes for small for example (Bb) the physical appearnce is Tall.
Over generations, small changes in the amount of each type of gene can happen because of several processes. Those processes are Gene mutation, Gene flow, Genetic drift, and Natural selection.
Dominant gene. The gene represented by a lower case letter is called the Recessive gene.
A small letter stands for a recessive allele.
a dominant gene is symbolized by a capital letter. a recessive gene is symbolized by a lower case letter.
