What are the general criteria for selecting organisms to perform crosses to study the inheritance of a few traits?

A person has to perform crosses for the purpose of studying inheritance of a few traits/ characters. What should be the criteria for selecting the organisms?

True or False. If false, write the correct sentence The branch of biology which studies the transfer of characteristics of organisms from one generation to the next, and genes in particular, is called genetics.

What is Criss-Cross Inheritance

What is responsible for determining characters of the organisms as well as its inheritance.

A plant bearing yellow flowers was crossed with a plant bearing red flowers. The F_1 progeny showed orange flowers. What is the inheritance pattern followed ?

Paragraph based questions : Read the following paragraph and answer, the questions based on it. The presence or absence of organs is the first, criterion for classification of plants. The presence or absence of separate conducting tissues for conduction of water and food is the next consideration for classification. Do the plants bear seeds? If they do then, whether the seeds are enclosed in a fruit or not is also an important criterion for classification. Finally, plants are grouped depending upon the number of cotyledons in the seeds. In 1883, Eichler, a botanist, classified the Kingdom Plantae into two sub-kingdoms. As a result, two sub-kingdoms, cryptogams and phanerogams were considered for plant classification. What are the two groups based on the criteria of whether the seeds are enclosed in a fruit or not?

Enlist seven traits of pea plant selected/studied by Mendel.
