Question
One homozygous fruit variety produces fruit averaging 18g in weight, while another homozygous fruit variety produces fruit averaging 8g. The F_1 obtained by crossing these two plants has fruit weight ranging from 11 to 15g . The F_2 produces plants with fruit weight ranging from 8 to 18g. Which generation shows the greatest amount of variation, the F_1 or F_2? How much does each contributing allele add to the mass to the fruit in grams (assume that every allele is equally contributing ie. each allel adds the same mass)?Explanation / Answer
1. There seems to be 4 gene contributing the mass of fruit.
2. generation F2 shows max variation.
3. one fourth of mass is expected to be influenced by allele.
