DESCRIBE THE PROCESS OF PHOTOSYNTHESIS AND RESPIRATION

1 answer:

3 0

IgorLugansk [536]

Answer:

0.0177

Explanation:

Cystic fibrosis is an autosomal recessive disease, thereby an individual must have both copies of the CFTR mutant alleles to have this disease. The Hardy-Weinberg equilibrium states that p² + 2pq + q² = 1, where p² represents the frequency of the homo-zygous dominant genotype (normal phenotype), q² represents the frequency of the homo-zygous recessive genotype (cystic fibrosis phenotype), and 2pq represents the frequency of the heterozygous genotype (individuals that carry one copy of the CFTR mutant allele). Moreover, under Hardy-Weinberg equilibrium, the sum of the dominant 'p' allele frequency and the recessive 'q' allele frequency is equal to 1. In this case, we can observe that the frequency of the homo-zygous recessive condition for cystic fibrosis (q²) is 1/3200. In consequence, the frequency of the recessive allele for cystic fibrosis can be calculated as follows:

1/3200 = q² (have two CFTR mutant alleles) >>

q = √ (1/3200) = 1/56.57 >>

- Frequency of the CFTR allele q = 1/56.57 = 0.0177

- Frequency of the dominant 'normal' allele p = 1 - q = 1 - 0.0177 = 0.9823

Explanation:

Homozygous individuals have two copies of the same allele for a gene. Homozygous dominant individuals carry two copies of the dominant allele, while homozygous recessive individuals carry two copies of the recessive allele.

Further Explanation:

DNA sets contain genes that may have different forms named alleles. DNA, which is the genotype, is transcribed into mRNA and later translated into amino acids which are connected together by rRNA to form proteins which constitute the phenotype of an organism. DNA sequence mutations form new allles, impacting the resulting mRNA, and thus the encoded protein. Within species, there may be adaptation, along with genetic drift, preferential breeding, and natural selection.

Within a population certain alleles are fixed over time. In Hardy-Weinberg-allelic frequencies, the equilibrium for a particular gene is not undergoing evolution, being stable for several generations. Mutations, during this time affect the corresponding mRNA, and thus the encoded protein. Evolution may occur within populations, along with genetic drift, selective mating, and natural selection.

Over time, certain alleles become fixed within a population. Equilibrium for a specific gene is not undergoing evolution in Hardy-Weinberg-allelic frequencies are stable for several generations. During this period, mutations do not occur within the population, this is shown as

$p^{2} + 2pq +q^{2} = 1$ ....(eqn i)

where...

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= frequency of the heterozygous genotype

and simply p+q= 1 ...(eqn ii)

The allelic freq. of r is denoted by q and the allelic frequency, R is denoted by p...

The total number of individuals= 32+ 68= 100

Thus q= √ $q^{2}$ = homozygous recessive individuals (white flowers)

Since there are 32 white flowering plants , freq rr= 32÷ 100= 0.32

...thus $q^{2}$ =0.32

and q= √ $q^{2}$ = √0.32= 0.566
