关键差异 - 基因频率与基因型频率
现在,人口由于出现的流行趋势,遗传学家已成为一个广泛研究的领域物种。Thus, population genetics can be measured through微发展where theevolution人口小人口的分析allele频率或基因频率、基因型频率nd phenotypic frequency. These calculations are done in order to determine the similarity of a population and to develop evolutionary relationships amongst different species in a population over a period of time. The frequency determines the number of times a particular gene,genotype or phenotype在特定人群中重复。基因频率和基因型频率之间的关键差异在于确定频率的特定因素。In gene frequency, it is a gene or an allele that determines the frequency while, in genotypic frequency, it is a genotype that determines the frequency.

What is Gene Frequency?
该基因是从父母转移到后代一代的遗传单位。控制后代特征的信息存储在这些基因中。每个基因都以替代对存在,等位基因是基因的另一种形式。基因频率或多或少是指等位基因频率,是在一定时间段内测量同一等位基因的重复序列的测量值。因此,基因频率(等位基因频率)指基因等位基因在人群中出现的频率。
The gene frequency can be measured in a micropopulation by using a simple formula as follows, and the value is usually given as a percentage.
等位基因的频率“ a” =人口中的等位基因“ a”的副本数量÷a/a的总数
基因频率Calculation
示例01:
Calculation of gene frequency of a flowering plant population with a主导等位基因P for purple color plants and a隐性等位基因p for white color plants is worked below.
人群中的基因总数= 1000
Gene frequency for gene P = [{(320 x 2) +160}/1000] x 100
= 80%
基因p = [{(20 x 2)+160}/1000] x 100的基因频率
= 20%
什么是基因型频率?
基因型是特定的遗传表达特征或一个特征,并涉及两个或多个等位基因,以产生特定的表达。基因型可以是纯合(alleles are of the same form – PP) or杂合(等位基因不同形式 - pp)。基因型频率测量是指特定基因型在给定时间段内在人群中表达了多少次。从而可以确定人群中的遗传关系。
基因型频率计算
As per the example given in gene frequency calculation, the genotypic frequency can be calculated in the following manner and is expressed as a percentage.
基因型的总数= 500
PP的基因型频率= [320/500] x 100 = 64%
pp的基因型频率= [160/500] x 100 = 32%
Genotypic frequency of pp = [20/500] x 100 = 4%
What are the Similarities Between Gene Frequency and Genotypic Frequency?
- 基因频率和基因型频率是在特定人群中测量的,最好是在微型人群中。
- Both percentages are measured within a particular time period.
- 两个值均表示为百分比。
- 两种测量都用于确定选定人群中的遗传关系。
基因频率和基因型频率有什么区别?
基因频率与基因型频率 |
|
基因频率是在所选时间段内重复在给定人群中重复的特定基因/等位基因的百分比。 | 基因型频率是在选定的时间内重复基因型的百分比。 |
进化率 | |
基因频率在基因库中迅速发展。 | Genotypic frequency evolves at a slower rate within the gene pool. |
结构 | |
基因频率可以主导或隐性。 | Genotypic frequency can be homozygous dominant, homozygous recessive or heterozygous. |
测量的复杂性 | |
基因频率更为复杂,因为它在等位基因水平上进行了测量。 | 基因型频率不那么复杂。 |
摘要 - 基因频率与基因型频率
The gene pool which consists of the total number of genes in a particular population constantly evolves as species undergo adaptations for environmental and other physical factors surrounding them. Hence, geneticists use changes in genes and genotypes to study the evolutionary patterns over a period of time. The gene frequency and genotypic frequency are measurements conventionally determined through Mendel’s theories but advanced with the theories put forward by Darwin on evolution. Allele or gene frequency is a measure of the relative frequency of an allele on a genetic locus in a population. Genotypic frequency is the proportion of a particular genotype amongst all the individuals in a population. This is the difference between gene frequency and genotypic frequency.
