Scientists and farmers use selective breeding to improve the characteristics of plants and animals. This includes genetic sequencing - a process which allows scientists to determine the precise sequence of DNA nucleotides for a living organism.
Which of the following is a consequence of inbreeding?
Increased yield and increased disease resistance
Decreased yield and decreased size
Decreased yield and increased size
By what means can new alleles be introduced to a plant cultivar that is beginning to show inbreeding depression?
What is the minimum number of replicates that should be used in a plant field trial?
How many treatments should be investigated in a plant field trial?
What result would inserting the Bt toxin gene into plants have?
They would have greater tolerance of drought
They would have greater tolerance of herbicide
They would have greater resistance to pests
