Answer:
Frequency of B allele is 0.6681
Explanation:
If p represents the frequency of dominant allele and q represents the frequency of recessive allele, according to Hardy-Weinberg equilibrium:
p + q = 1
p² + 2pq + q² = 1
where p² = frequency of homozygous dominant genotype
q² = frequency of homozygous recessive genotype
2pq = frequency of heterozygous genotype
Given that number of recessive chestnut horse = 28
Total horses = 226 + 28 = 254
frequency of b² genotype = 28/254 = 0.1102
frequency of recessive b allele = √0.1102 = 0.3319
So, frequency of B allele =
1 - 0.3319 = 0.6681
Hence frequency of B allele is 0.6681
Answer:
a. Light and carbon reactions occur in separate cells.
b. ATP is used to move a three-carbon ferry molecule from bundle-sheath cells back to mesophyll cells.
c. They require less water to live.
g. These plants function better in the hot, sunny environments.
Explanation:
The plants which carry out C₄ pathway or Hatch and Slack pathway are called C₄ plants. Examples are maize, sugar cane, sorghum. They live in hot, dry or arid habitats. C₄ plants have dimorphic chloroplast. The chloroplast is in bundle sheath cells does not have grana and in the spongy mesophyll cells have chloroplasts with grana. So, light and carbon reactions occur in separate cells. C4 plants are more efficient in photosynthesis than the C₃ plants. There is no photorespiration in C₄ plants as Phospshoenol pyruvate (PEP) carboxylase enzyme.
