To describe:
The trait that appears to run in an individual’s family.
Introduction:
Any individual’s characters, behavior, and appearance are the expression of traits which organism contains. A trait can be made up of two similar allele and termed as homozygous, and the heterozygous allele made-up of two different allele.
To describe:
The trait runs in individual family because inheritance or the environmental factors that is common to family members.
Introduction:
Inheritance is the method by which the alleles get transferred along the generations. Inheritance is a sharing of characters between parents and their child.
To distinguish:
The possibilities that the trait runs in individual family because inheritance or the environmental factors that are common to family members.
Introduction:
An allele represents different form of a particular gene, present on chromosome. A gene is responsible for a trait and variation in that particular trait is shown by different alleles. The genotype is the genetic content of the organism which determines the phenotype. On a larger extent a phenotype is defined by genotype and environmental factor
