Show the phenotypical type and genetical ratios with the aid of a Punnet square for a dihybrid cross of TTBB (Female) x ttbb (Male), where T and B represents big Teeth and big Body and t and b representing small teeth and small body respectively of the organism. For easy understanding these traits of this organism only appears in two forms (big and small).
Answers
Respiration is a process in which glucose is broken down with the help of oxygen and energy is released along with the production of carbon dioxide and water.
Answer:
Below is a sampling of Punnett Square problems that you will be expected to solve. In order to do this, you will have to understand the meaning of the terms below.
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. If the traits you are using are dominant or recessive, this trait will "overpower" the recessive trait and will be expressed. E.g. Tt
Recessive trait: Signified by small case letter-e.g. t. An organism with a recessive allele for a particular form of a trait will have that form only when the dominant allele for the trait is not present
Homozygous: Has same letters. E.g. TT or tt (same alleles for trait)
Heterozygous: Has different letters. E.g. Tt (different alleles for trait)
Purebred trait: Also known as true breeding. Individuals genotype is homozygous and will only make one type of gamete. E.g TT will always produces T, and T. tt will always produce t, and t.
