Respuesta :
In genetics, the physical characteristics are referred as phenotype. Each character such as hair color in offspring is determined by a pair of genes. One gene is inherited from father and other gene is inherited from mother. The phenotype is determined by the dominant gene. The recessive gene of a pair does not show its effect in heterozygous condition. Therefore, the offspring inherits a dominant gene and a recessive gene then the dominant gene will show the character. This is called Mendel’s law of dominance.
The physical factors are referred as phenotype. Each factor such as hair color in offspring is specified by a pair of genes. One gene is inherited from father and other gene is inherited from mother.
What causes hair color changes?
Hair color changes result not only from modification of melanin production but also from alters in the hair structure itself, altering its visual properties.
A mixture of genetic, metabolic, nutritional, and developed disorders result in hair color changes.
Thus, Each factor such as hair color in offspring is specified by a pair of genes. genes are inherited from both parents.
