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:
an aerobic respiration is the type of respiration that uses oxygen to provide energy for the body
an anaerobic respiration is the type of respiration that does not use oxygen to provide energy for the body
to provide energy
carborn dioxide
glucose+oxygen =carbon dioxide +water +energy
