The process by which plants are bred to produce larger fruits and longer rowing time is called

• dominant breeding

• recessive breeding

• offspring breeding

• selective breeding

What is the name used to describe a cross between two varieties of plant used in an attempt to create new variety of with traits from both parents

• cloning

• hybridization

• polyploid planting

• selective breeding

What is the name of the method whereby developing pure lines, breeders, preserve desirable traits?

• hybridization

• inbreeding

• cross pollination

• mass selection

in a test cross, if one parent's genotype is homozygous dominant

• all the offspring will have the dominant genotype

• 3/4 of the offspring will have the dominant phenotype

• 1/2 of the offspring will have the domiant phenotype

• 1/4 of the offspring will have the dominant phenotype
