In plants, green color dominates over white. When crossing green plants, 44 offspring were obtained, of which 11 were white and died. What was the genotype of the parents? What was the green in the offspring? What kind of white plants?
Let us designate the gene that leads to the development of green color in the considered plants as C, then the gene for their white color will be designated as c.
The splitting obtained when crossing green plants – 3: 1, is characteristic of the Mendelian type of crossing heterozygotes.
Let’s write the parent green plants as Cc. They produce C and C germ cells.
The offspring are represented by the following options:
white plants that die (cc) – 25%;
green plants – homozygotes (CC) – 25%;
green plants – heterozygotes (Cc) – 50%.
