Question

When does offspring show a blend of parent traits?

Answer 1

Hint: The biological process of passing of traits from parents to offsprings either through sexual or asexual reproduction is known as heredity. It is also known as inheritance or biological inheritance, in which the genetic information is passed from parents to offspring.

Complete answer:
Heredity also known as inheritance or biological inheritance is process of passing of traits from parents to offsprings either through sexual or asexual reproduction. In this process the genetic information is passed through DNA from parents to offspring. The study of heredity and variations is known as genetics.

Through the process of heredity, variations occur between two individuals and causes the evolution by the process of natural selection. In humans, eye color is a classical example of an inherited trait from parent to offspring. The traits are passed from one generation to another by DNA which encodes all the genetic information. DNA is a long polymer of nucleic acid sequences which carries the specific genetic information.

In each and every organism, genes occur in pairs and each pair is inherited from each parent. Gregor Mendel was the first person to describe how the traits are passed from one generation to another. With the help of a breeding experiment of pea plant (Pisum sativum), he proposed three laws of inheritance which described how the genetic traits will transfer from parents to offspring.

Blending inheritance is an obsolete theory in biology. This theory is about progeny inherit the average characteristic from its parent. Darwin theory of inheritance with contribution of egg and sperm implied blending inheritance. Blending inheritance was discarded with general acceptance of Mendelian inheritance.
