Monohybrid Cross
“A monohybrid cross is the hybrid of 2 individuals with homozygous genotypes that result in the opposite phenotype for a certain genetic trait.”
“The cross between two monohybrid traits (for instance, TT and tt) is called a Monohybrid Cross.”
How To Carry Out A Monohybrid Cross?
These are the steps used in order to calculate a monohybrid cross:
- Indicate the alleles operating characters – dominant alleles can be indicated by upper case letters while recessive alleles can be indicated by lower case letters.
- Note down both the genotype and the phenotype of the parents or the parental generation that are being crossed.
- Markdown the genotype of the gametes from the parental generation – As an outcome of meiotic division, the gametes will be haploid.
- Tabulate a Punnett square to arrange the probable combinations of the gametes – Any combination is possible as the process of fertilization is at random.
- The genotype and the phenotype ratios of the prospective offspring can be written. The outcome hence acquired is known as the F1 generation. The F2, F3, etc, generations form the subsequent generations.
