Geometric Characteristics-Geometric characteristics refer to the basic elements or building blocks which form the language of geometric dimensioning and tolerancing. Generally, the term refers to all the symbols used in form, runout, profile and locational tolerancing. Geometrical Characteristics-Geometrical characteristics refer to the basic elements or building blocks, which form the language of geometric dimensioning and tolerancing. Generally, the term refers to all the symbols used in form, runout, and locational tolerancing. Definition Per.
Parent 1 and 2 have each 5 possible genotypes (OO, AO, BB, BO and AB). Here a Punnett square with each possibilities. I highlighted the possible parent genotypes. The total number of possible crosses is exactly 21. Note that here A = Ia, B = Ib and O = i. 1  OOxBB,OOxBO,OOxAB. 2  AOxBB,AOxBO,AOxAB.
The normal diploid number of chromosomes is constant for each species. For humans, the diploid number is 46 (23 pairs in all somatic cells). In the formation of gametes (ovum and spermatozoon), the number is reduced to one half (haploid number); i.e., the ovum and sperm each contain 23 chromosomes. Of these, 22 are autosomes and one is the sex chromosome (X or Y).
