Gene is the correct answer
Answer:
C. 40
Explanation:
Pure-breeding means that the individuals are homozygous for the genes being analyzed.
From Mendel's Law of Dominance we know that the traits that appear in the F1 are the dominant ones.
I will call:
P_ = purple flowers
pp = red flowers
L_ = long pollen
ll = round pollen
Initial cross:
P Pl/Pl x pL/pL
F1 Pl/pL
<u>Test cross</u> (cross with a homozygous recessive individual):
Pl/pL x pl/pl
<u>Expected progeny:</u>
Pl/pl = Parental (purple flowers, round pollen)
pL/pl = Parental (red flowers, long pollen)
PL/pl = Recombinant (purple flowers, long pollen)
pl/pl = Recombinant (red flowers, round pollen)
20% of the offspring have purple flowers and long pollen (PL/pl).
Every time crossing over happens in the meiosis of the F1 individual, both a <em>PL</em> gamete and a <em>pl</em> gamete form. That means that 20% of the offspring will also be pl/pl, and the total proportion of the offspring that will be recombinants will be 40%.
A distance of 1 map unit corresponds to a recombinant frequency of 1%.
A recombinant frequency of 40% therefore means that 40 map units separate the glower color and pollen shape genes.
The sounds of music are related to trigonometric functions in the fact that the sound can be measured according to the angles of the sound waves.
<h3>What is sound?</h3>
Sound is a disturbance on a specific media (e.g., air) that travels with a particular frequency and amplitude.
Sound amplitude is represented by the height of the wave, whereas sound frequency is referred to as the period of time between waves.
In conclusion, the sounds of music are related to trigonometric functions in the fact that the sound can be measured according to the angles of the sound waves.
The graph below shows how trigonometric functions are associated with sound waves.
The trigonometric function used in the graph to understand the movement of sound waves is Y=sin(X).
