. In foxgloves, three different petal phenotypes exist:white with red spots (WR), dark red (DR), and lightred (LR). Two different kinds of true-breeding WRstrains (WR-1 and WR-2) can be distinguished bytwo-generation intercrosses with true-breeding DRand LR strains:F2Parental F1 WR LR DR1 WR-1 × LR all WR 480 39 1192 WR-1 × DR all WR 99 0 323 DR × LR all DR 0 43 1324 WR-2 × LR all WR 193 64 05 WR-2 × DR all WR 286 24 74 a. What can you conclude about the inheritance ofthe petal phenotypes in foxgloves?b. Ascribe genotypes to the four true-breeding parental strains (WR-1, WR-2, DR, and LR).c. A WR plant from the F2 generation of cross 1 isnow crossed with an LR plant. Of 500 total progeny from this cross, there were 253 WR, 124 DR,and 123 LR plants. What are the genotypes of theparents in this WR × LR mating?

Inheritance and Mendelian Genetics

Inheritance means the passing of traits to offspring from parents. These traits could be passed either through asexual reproduction or sexual reproduction. The offspring receives the genetic material from the parents. Mendelian inheritance is a certain biological inheritance that follows the rules and principles laid down by Gregor Mendel in 1865. The initial hypothesis was considered wrong, but other inheritance theories modified the concept of inheritance and thus genetics.
