Answer: Option B.
Necessary for the transport of dietary lipids
Explanation:
Lacteals are specialized lymphatic capillaries that are finger like projections that extend into the small intestine. They are found in the intestinal villi of small intestine.
They transport absorbed dietary fats from the small intestine into the blood stream.
The insects obvi bc they need food
Answer: The frequency of GG is 0.64
Explanation: using Hardy-weinberg equation
g^2 + 2Gg + G^2 =1 ................(1)
And the sum of the alleles at the locus must be 1.
Therefore:
G + g = 1 ..............................(2)
Since
G=0.8
g= 0.2
G^2 =GG (Homozygous G gene)
g^2 = gg (Homozygous g gene)
Using equation 1
GG+ (2×0.8×0.2) + gg =1
Therefore
GG + 0.32 + gg = 1
GG + gg = 0.68...............(3)
Solving equation 2
G + g = 1
g = 1 - G
Square both side
g^2 = (1 - G)^2 ...............4
Where g^2 = gg
Therefore gg = (1 - G)^2.............(5)
Substitute equation 5 into equation 3
GG + (1 - G)^2 = 0.68
Therefore
GG = 0.68 - (1 - G)^2
GG = 0.68 - (1 - 0.8)^2
GG = 0.68 - 0.04
GG = 0.64
Answer:
Epistasis is a phenomenon in Genetics in which mutations on one gene locus are dependent on the mutations on some other genes locus. In other words, the expression of a phenotype of one gene is dependent on the presence or absence of mutations on other gene.
Dominance is phenomenon in genes in which a particular genotype masks the expression of alternative genotype and expresses itself due to complete takeover over other.
