Document Summary
Kolreuter concluded that both parents make equal genetic contributions to their offspring. Gregor mendel, born in 1822, is now considered the father of genetics. Gamete is used to describe the haploid reproductive cells that fuse to form a zygote. Mendel wanted to carry out self-fertilization, which means that the pollen and egg are derived from the same plant (peas naturally produce by self-fertilization) Cross-fertilization requires that pollen from one plant be placed on the stigma from another plant. The general characteristics of an organism are called characters. The terms trait or variant are typically used to describe the specific properties of a character: for example, eye color is a character of humans and blue eyes is the trait. A variety that continues to produce the same trait after several generations of self-fertilization is called a trued-breeding strain or true-breeding line. A cross in which an experiment observes one character is called a single-factor cross.
