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.
The answer is C. <span> Accessibility to nutrients makes the mouth a favorable habitat.

Answer:
The object's velocity is increasing
Explanation:
From the graph above, we can deduce that the velocity is increasing. From the first stage, v=m/s=0.
At the third stage, v=20/2= 10m/s.
At the 5th stage, v=80/4=20m/s.
This shows velocity is increasing.
It allows the individual in a populations to survive and have offspring with the desire trait needed to live while those without will die out
