Hey there! :)

To solve a Punnett square, we need to master the fields in the attached picture

In the question, the given keys are:
Dominant allele Y → yellow
Recessive allele y → green

                    Y      |       y

      Y     |    YY            Yy

      Y     |    YY            Yy

This would be the Punnett square for this question
  
Percentage of offspring to have yellow seeds?

Yellow is Y, then we should count which alleles had YY as a genotype?

YY = 2 out of 4, then 50%

Explain what would happen if water did not expand when freezing. How would this impact aquatic life?
Lapatulllka [165]

Explanation:

If water did not expand when freezing, then it would be denser than liquid water when it froze; therefore it would sink and fill lakes or the ocean from bottom to top. Once the oceans filled with ice, life there would not be possible.
