Answer:
1/4
Explanation:
Given that the F2 cross produces offspring according to the expected 9:3:3:1 ratio.
YyRr X YyRr:
Let us break the dihybrid cross into individual monohybrid crosses.
Yy X Yy :
Y y
Y YY Yy
y Yy yy
2/4 or 1/2 of the offspring are heterozygous for the trait.
Similarly, in Rr X Rr cross, 1/2 of the offspring are heterozygous for the trait.
Together, 1/2 * 1/2 = 1/4 of F2 plants are expected to be heterozygous for both traits.
Answer:
Derived traits shared among the species or other groups in a dataset are key to helping us build trees. As shown above, shared derived traits tend to form nested patterns that provide information about when branching events occurred in the evolution of the species.

Answer:
As objects move around over time, the energy associated with them—e.g., kinetic, gravitational potential, heat—might change forms, but if energy is conserved, then the total will remain the same. Conservation of energy applies only to isolated systems.
Explanation:
Since Australia is located in the Pacific ocean, extremes of weather and climate happen throughout a season. El Niño is traditionally defined as a dry climate with reduced rainfall; in this happens to be more extreme in Australia because of its location. La Niña on the other hand is traditionally defined as a wet or cool climate with lots of rainfall; and this is indifferent as La Niña in Australia tend to be more extreme too.
Where are the questions cuz I don’t seem them either
