<span>New tree species discovered with cone-like features and have seeds as its covering are called pine trees. These pine trees have pine cones which is their reproductive structure. These pine cones are seeds exposed outside the trees. The pine cones belong to the plant group called gymnosperms.</span>
So, since the trait is eye color, let's use E to represent the dominant allele (brown) and e to represent the recessive allele (blue).
I've attached a Punnett square, but let me real quick explain how I set it up. We know that both parents are heterozygous, which means that they have one of each allele. So that gave us the two sides. Then I filled in the boxes (I assume you've leaned how to do this, if message me and I can explain it).
Looking at the results we can see that 1/4 of the offspring are EE, 1/2 are Ee, and 1/4 are ee. Since the blue allele (e) is recessive, it'll only be expressed if no dominant brown alleles (E) are present. Therefore, only the ee genotype will exhibit blue eyes. So, 1/4 or 25% of the offspring will have blue eyes.
Hope that helps! If you need clarification or anything feel free to message me :)
It take about an average of about 8min and 20sec
Bellow I attached the punnet square you need. From it you can see, that the likelihood of producing an offspring with attached earlobes is 25% (ff)
