Answer:
See the answers below
Explanation:
Assuming that D (d) represents the allele for wing type and E (e) represents the allele for body type, crossing DdEe with DdEe will yield the following offspring according to the Punnet's square (see the attached image):
(a) <em>9/16 D_E_ wild type </em>
<em> 3/16 D_ee wild wing, ebony body</em>
<em> 3/16 ddE_ dumpy wing, wild body</em>
<em> 1/16 ddee dumpy wing, ebony body</em>
(b) Chi square 
= 
, where O = observed frequency and E = expected frequency.
Phenotype O E
Wild type 473 9/16 x 830 = 466.875 
= 0.08
wild w/ebony b 156 3/16 x 830 = 155.625 
= 0.0009
Dumpy w/wild b 149 3/16 x 830 = 155.625 
= 0.28
dumpy w/ebony b 52 1/16 x 830 = 51.875 
= 0.0003
Total = 0.3612
Degree of freedom = 4 - 1 = 3
Tabulated value of (0.05)= 7.815
(c) <em>Since the calculated Chi square value is less than the tabulated value, we conclude that the observed outcome agrees with the expected outcome and that the cross followed the standard Mendelian pattern.</em>
Answer: The correct answer for the blank is-
evens out genetic differences between populations
Gene flow or migration of gene can be described as a process of transfer of genetic variation from one population into another population. This process leads to change in the frequency of a gene variant ( that is called allele) in a particular population and it reduces the genetic differences between population.
If the process of gene glow is high, then the two population will be considered equivalent in genetic diversity.
Thus, Gene flow evens out genetic differences between populations
Photosynthesis removes carbon dioxide from the atmosphere while cellular respirations puts back the carbon dioxide.

You Asked ➤ The goal of basic science is:
↴ OUR CHOICES ↴
A: To increase our understanding of general principles.
B: To improve a specific situation.
C: To solve a particular problem.
D: To use technology to improve quality of life.
------------------------------------------------------------------------------------
Answer ➤ A: To increase our understanding of general principles.
Explanation: One of the major goals of basic science is understand what the key principals that make it up. We learn how it functions and understand what make science part of our world.
••• HUH? WHY IS IT NOT THE OTHER CHOICES? •••
⇢ <u>B and C:</u> While basic science does help improve situations and solve problems, that is not the main reason why it is studied.
⇢ <u>D:</u> Science has helped us use more technology, but those levels are more advanced than the general basics.
I hope this answer is helpful to you, but please let me know if you have any other questions regarding it.
