Answer:
500
Explanation:
According to the given information, the total number of albino people in the population= 1000/4 = 250.
Since albinism is an autosomal recessive trait, the genotype of albino people would be homozygous recessive. Therefore, the frequency of homozygous recessive genotype in the population (q2) = 250/1000= 0.25.
The frequency of recessive allele (q) = square root of 0.25 = 0.5
Since p+q=1. So, p (frequency of dominant allele) = 1-q = 1-0.5 = 0.5
Frequency of heterozygotes in the population= 2pq = 2 x 0.5 x 0.5 = 0.5 or 50%
Therefore, expected number of heterozygotes in the given population= 50% of 1000 = 500
the answer A, steroids ; separate the cytoplasm from the environment
Explanation:
In Hardy-Weinberg equilibrium...
p represents the dominant allele frequency
q represents the frequency of the recessive allele
q^2 = the genotypic frequency of the homozygous recessive
p^2= the genotypic frequency of the homozygous dominant
2pq= the frequency of the heterozygous genotype
Further Explanation:
Sequences of DNA make up genes which can have different forms called alleles. DNA, which makes up the genotype, is transcribed into mRNA and later translated into amino acids which are linked together by rRNA to form proteins which make up the phenotype of an organism. Mutations in DNA sequences form new alleles, and affect the corresponding mRNA and thus the protein encoded. Along with genetic drift, selective mating and natural selection, evolution may occur within populations.
Some alleles become fixed within a population over time. In Hardy-Weinberg equilibrium for a specific gene that is not undergoing evolution- allelic frequencies are stable over several generations. During this period, mutations do not occur within the population.
