Introduction:
In a population of 5000 individuals, 450 individuals show a recessive trait. We need to determine the number of heterozygous individuals in this population.
Explanation:
To find the number of heterozygous individuals, we first need to understand the inheritance pattern of the recessive trait. Let's assume that the trait is determined by a single gene and follows a simple Mendelian inheritance.
Mendelian Inheritance:
In Mendelian inheritance, each gene has two alleles, one inherited from each parent. There are three possible genotypes for a single gene: homozygous dominant (AA), homozygous recessive (aa), and heterozygous (Aa).
- Homozygous dominant individuals (AA) will not show the recessive trait.
- Homozygous recessive individuals (aa) will always show the recessive trait.
- Heterozygous individuals (Aa) will not show the recessive trait but can pass it on to their offspring.
Calculating the number of heterozygous individuals:
Since 450 individuals show the recessive trait, we can assume that they are homozygous recessive (aa). The remaining individuals (5000 - 450 = 4550) must be either homozygous dominant (AA) or heterozygous (Aa).
Since heterozygous individuals do not show the recessive trait, the number of heterozygous individuals can be calculated by subtracting the number of homozygous recessive individuals (aa) from the total population.
Number of heterozygous individuals = Total population - Number of homozygous recessive individuals
Number of heterozygous individuals = 5000 - 450
Number of heterozygous individuals = 4550
Therefore, the number of heterozygous individuals in this population is 4550.
Conclusion:
In a population of 5000 individuals, with 450 individuals showing a recessive trait, the number of heterozygous individuals is 4550. This calculation is based on the assumption that the recessive trait follows Mendelian inheritance, where heterozygous individuals do not show the recessive trait but can pass it on to their offspring.
