WebThe cross between the true-breeding P plants produces F 1 heterozygotes that can be self-fertilized. The self-cross of the F 1 generation can be analyzed with a Punnett square to predict the genotypes of the F 2 generation. Given an inheritance pattern of dominant–recessive, the genotypic and phenotypic ratios can then be determined. WebApr 9, 2024 · Silent Changes. After mutagen treatment, the vast majority of base pair changes (especially substitutions) have no effect on the phenotype. Often, this is because the change occurs in the DNA sequence of a non-coding region of the DNA, such as in inter-genic regions (between genes) or within an intron region. Also, even if the change …
