We can use a punnett square to predict the outcome of self-fertilization for the f1 hybrids of a monohybrid cross. In this case, the punnett square should be set up as a blank 2x2 square.
Self-fertilization is the joining of male and female gametes and/or nuclei from the same haploid, diploid, or polyploid organism. It is an instance of extreme inbreeding. These are 2X2 squares with four boxes for a monohybrid cross, with each box signifying a fertilization between the parent gametes.
Selfing is widespread, ranging from simple hermaphrodite plants and animals to multicellular organisms (especially invertebrates). Selfing occurs when two individuals (or their cell nuclei) that were produced by a previous mitotic division of the same individual interbreed in unicellular organisms like protozoa.
The Punnett square is a table that lists every conceivable result of a genetic cross between two people of known genotype. The Punnett square is a square that has been partitioned into four quadrants in its most basic form.
