WebApr 9, 2024 · If the genes are linked, there will often be two phenotypic classes that are much more infrequent than any of the others. In these cases, the rare phenotypic classes are usually those that arose from two crossover events, in which the locus in the middle is flanked by a crossover on either side of it. WebMar 1, 2024 · Dominant inheritance. Dominant gene variants are misspellings (mutations) that occur in one copy of the gene pair while the other copy of the gene is spelled correctly. Dominant variants can cause HI in a person even if the other copy of the gene is normal. Sometimes a dominant gene variant is inherited from a parent, and sometimes it is a new ...

WebApr 9, 2024 · Crossing over begins with the breakage of DNA of a pair of non-sister chromatids. The breaks occur at corresponding positions on two non-sister chromatids, and then the ends of non-sister chromatids are connected to each other resulting in a reciprocal exchange of double-stranded DNA (Figure 7.4. 4 ).
