Advantages

Emails are delivered extremely fast when compared to traditional post.
Emails can be sent 24 hours a day, 365 days a year.
Webmail means emails can be sent and received from any computer, anywhere in the world, that has an internet connection .
Cheap - when using broadband , each email sent is effectively free. Dial-up users are charged at local call rates but it only takes a few seconds (for conventional email, eg text only) to send an email.
Emails can be sent to one person or several people.

What are contributions of Mendel for inheritance of traits?

Posted by Gm Ahmed 5 years, 7 months ago

CBSE > Class 10 > Science

1 answers

Meghna Thapar 5 years, 7 months ago

Gregor Mendel, through his work on pea plants, discovered the fundamental laws of inheritance. He deduced that genes come in pairs and are inherited as distinct units, one from each parent. Mendel tracked the segregation of parental genes and their appearance in the offspring as dominant or recessive traits. Mendel carried out his key experiments using the garden pea, Pisum sativum, as a model system. Pea plants make a convenient system for studies of inheritance, and they are still studied by some geneticists today.
