Because a scientific theory is something that has been proven over the trials of many tests
Hope that helps :)
The
correct answer is the gastrocnemius muscle.
<span>The
gastrocnemius muscle is a muscle located in the back part of the lower leg of
humans. The gastrocnemius together with the soleus muscle forms half of the
calf muscle with the function is plantar flexing the foot at the ankle joint
and flexing the leg at the knee joint.</span>
Answer:
(a) Frequency of M = 0.64
Frequency of N = 0.04
Frequency of MN= 0.32
(b) Expected frequencies of M = 0.648
Expected frequencies of MN = 0.304
Expected frequencies of N = 0.048
Explanation:
(a) If random mating takes place in the population, then the expected frequencies are
f(L(M)) = p = 0.8
F(L(N)) = q
q= 1 - p
= 1 - 0.8
= 0.2
Frequency of M = p^2 = ( 0.8)^2 = 0.64
Frequency of N = q^2 = (1-p)^2 = (1 - 0.8)^2 = (0.2)^2 = 0.04
Frequency of MN = 2pq = 2 * 0.8 * 0.2 = 0.32
(b)
F = inbreeding coefficient = 0.05
f(L(M)L(M)) = p^2 + Fpq = (0.8)^2 + 0.05 * 0.8 * 0.2 = 0.648
f(L(M)L(N)) = 2 pq - 2Fpq = 2 * 0.8 * 0.2 - ( 2 * 0.05 * 0.8 * 0.2) = 0.304
f(L(N)L(N)) = q^2 + Fpq = (0.2)^2 + ( 0.05 * 0.8 * 0.2) = 0.048
The genes, which are part of DNA, contain the<u> genetic information</u> inherited from the parents determine the traits of an organism.
The ‘complete set of all the genes and the DNA’ is called the genome which stores the entire set of information of how an organism is structured and maintained.
The pattern of dominant and/or recessive traits and the genetic variations are determined by the allelles.
Explanation:
The genetic codes in the genes represent the particular amino acid codes and their linkages specific to particular protein. The amino acids link together to form long polypeptide chains of protein molecules.
These proteins determine various traits through various roles like:
Messenger proteins: Hormones like insulin, estrogen etc., control and coordinate various functions of the body
Pigments: Like melanin determines the color of the hair, skin, eyes.
Structural protein: Like keratin gives structure of hair, nails; myosin determines muscle structure
Antibodies: Determine the immunity of a person
Ion channel proteins, messenger proteins, structural proteins, receptor proteins etc.: Determine various physiological traits.
