Answer:
One offspring would have red leaves.
Explanation:
Given 
Yellow leaves are dominant and red leaves are recessive
Let us assume that the trait of Yellow color of a leaf be  represented by "Y"
and the trait of red color of a leaf be  represented by "y"
When two parent of genotype "Yy" are crossed with each other, the following offsprings are produced as shown in the punnet square below
 Y	y
Y	YY	Yy
y	Yy	yy
Total four offpsrings are produced out of which only one has red leave as red color is a recessive trait and it will appear only when both the allele in a cell are of red color. 
Thus, one offspring would have red leaves.
