Plant Breeding and Genetics

Gene mapping

Gene sequencing

Identify new genes

All the above

Tall, leafy, high leaf/stem ratio

Late resistance to disease

Dwarf stature

Dwarf, late green

Epidermis

Plasma membrane

Nuclear membrane

Cellulose cell wall

Cancer

Gastrula

Zygote

New organ

All daughter cells will have different homologous chromosome pairs

All homologous chromosome pairs will separate

All dominant genes will segregate together into daughter cells

All linkage group will be disrupted

Linseed

Gram

Oat

Tomato

Dichotamy

Heterostyle

Heterospory

Dichogamy

Mather (1949)

Fisher (1918)

Wright (1921)

Smith (1936)

Small waxy and thick leaves

Deep root system

Sunken, small and less stomata

All of the above

Green plastids of male parent become nitrated

Albinism is dominant over green characters

Plastids are inherited through maternal parents

Crossing over results in structural changes in green plastids
