Answer:
d. Character displacement
Explanation:
Character displacement is the phenomenon in which the similar species living in the same geographical region with similar niches differentiate in order to reduce their niche overlap and avoid competitive exculsion. Just like in this case of two- spot and three -spot avenger beetles as their timmings for hunting is different where their ranges overlap. So it's the good example of character displacement,
Answer:
yes/no
Explanation:
1. looks correct!
2. i think that is the third choice because I learned that during interphase, the cell grows and makes a copy of its DNA. I learned this a while ago so I'm not 100% sure its correct. :)
I believe the answer is 172,800,000,000 per day (24 hours)
How I Got That Answer:
I calculated 2 million times 60
=120000000 per minute
Then I calculated that times 60 again
=7200000000 per hour
Then I calculated that times 24
=172800000000 per day
Answer:
a) The expected phenotype of the F1 plants is 100% RrBb, red kernels.
b) The expected phenotypic classes in the F2 are: 9:3:3:1
9/16 R-B-, 3/16 rrB-, 3/16 R-bb, 1/16 rrbb
Proportions 9:6:1.
9/16 Red kernel (R-B-), 6/16 Brown kernel (rrB- + R-bb), 1/16 White kernel (rrbb)
Explanation:
<u>Available data:</u>
- brown kernel: R-bb or rrB-
1º Cross) RRBB x rrbb
F1) 100% RrBb (red kernels)
2ºCross) RrBb x RrBb
Gametes) RB RB
Rb Rb
rB rB
rb rb
Punnet Square) RB Rb rB rb
RB RRBB RRBb RrBB RrBb
Rb RRBb RRbb RrBB Rrbb
rB RrBB RrBb rrBB rrBb
rb RrBb Rrbb rrBb rrbb
F2) Phenotypic classes:
<em>9/16 R-B-</em>
<em> 3/16 rrB-</em>
<em> 3/16 R-bb</em>
<em> 1/16 rrbb</em>
Phenotypic proportions:
<em>9/16 Red kernel (R-B-)</em>
<em> 6/16 Brown kernel (rrB- + R-bb)</em>
<em> 1/16 White kernel (rrbb) </em>
