The answer is D. Just think how hard it would be to see a moth of that colour when just about everything during that time period is grey.
Answer:
A) 0.1 a, 0.9 A
Explanation:
According to the given information, all the individuals in the founder population had free earlobes. Since the allele for the free earlobes (A) is dominant over the one for the attached earlobes (a), the genotype of each of the homozygous dominant founder individual would be "AA". Humans are diploid and one individual has two alleles for each gene in its genome. Total number of alleles for the earlobe in the founder population = 10 x 2 = 20.
Frequency of dominant allele, A in the founder population = total number of homozygous dominant individuals x 2 + the total number of heterozygous genotype / total alleles for the earlobe in the population. There were 8 homozygous dominant and 2 heterozygous dominant individuals in the population.
So, frequency of dominant allele = 8 x 2 + 2 / 20 = 16 + 2 / 20 = 18/20 = 0.9
Since p+q=1; frequency of recessive allele "a" = 1-p = 1-0.9 = 0.1
The answer would be C.
Plants that live in the canopy get way more sunlight than the ones that are on the forest floor. They have different adaptions that i can tell u about in the comments if it’ll help with what ur studying:)
vertebrae, sacrum, coccyx, temporal, sphenoid, ethmoid, zygomatic, maxilla, mandible, palatine, inferior nasal concha, and hyoid
Because atmospheric nitrogen can't be used by plants and animals. Only by soil. nitrification it is the conversion of ammonia first into nitrites then into nitrates by nitrifying bacteria and denitrification is the conversion of nitrites and nitrates into free nitrogen. Why are bacteria important to the nitrogen cycle?
