Dutch elm disease was spread by a fungus embedded on wood
This causes a net force on the object acting upwards. ... So, for objects that weigh less, per unit of volume than water, the buoyancy force will cause the object to float. For objects that weigh more, per unit of volume (i.e: are more dense) the buoyancy force can't quite win out and the object will sink.
Answer:
9/32 Pink, Tall and Normal individuals Rr Tt Nn
Explanation:
<u>Available data:</u>
- Red color RR
- Pink color Rr
- White color rr
- Normal NN and Nn
- Symmetrical nn
- Tall TT and Tt
- Dwarf tt
1st Cross:
Parental) rr TT NN x RR tt nn
F1) 100% RrTtNn
2nd Cross:
Parental) Rr Tt Nn x Rr Tt Nn
Knowing that these three genes assort independently, then we can infer that the F2 will have the next phenotypic proportions for each gene:
RR= 1/4 Red
Rr= 2/4 Pink
rr=1/4 White
TT + Tt= 3/4 Tall
tt=1/4 Dwarf
NN + Nn = 3/4 Normal
nn=1/4 Symmetrical
- The proportion of the F2 plants that will resemble Rr Tt Nn (Pink, tall, Normal) in Phenotype
Rr= 2/4 pink
TT + Tt= 3/4 Tall
NN + Nn = 3/4 Normal
2/4 x 3/4 x 3/4 = 18/64= 9/32
