So you multiply the percentages, like product rule in math. Let's say we are concerned with a cross between AaBb and Aabb. First treat the A gene. You can easily tell the phenotypic ratio is 3:1 or 3/4 to 1/4. for the other gene, it is 1:1 or 1/2 and 1/2. WebTo prepare a forked-line diagram for a cross between F 1 heterozygotes resulting from a cross between AABBCC and aabbcc parents, we first create rows equal to the number of genes being considered, and then segregate the alleles in each row on forked lines according to the probabilities for individual monohybrid crosses ( Figure 12.17 ). dry cleaners for leather jackets near me

WebOct 19, 2024 · A dihybrid cross is a cross between two different plant species that results in the production of offspring that are not purebred from either parent. The process of producing these offspring is called hybridization. Dihybrid crosses can be used to create new varieties or to improve the characteristics of existing plants. http://ib.bioninja.com.au/higher-level/topic-10-genetics-and-evolu/102-inheritance/dihybrid-crosses.html
