• eggs or sperm

• genetic variation

• all of these

Crossing over

• is where a pair of chromosomes trade copies of the same gene

• occurs during mitosis

• reduces genetic variation

• forms new gamete cells

Reproduction

• always creates clones of the parent organism

• always creates offspring with half their dna from each parent

• does not occur in plants

• transmits genetic material into the next generation

An egg cell or sperm cell

• is formed during mitosis

• contains all the dna of the parent organism

• has 23 chromosomes in a human

• has 46 chromosomes in a human

When a gene is changed

• the protein coded for by the gene is always changed

• the organism will not survive

• the organism might not show any changes in its traits

• all of these

Radiation is a mutagen because

• it can cause changes in a cell's DNA

• it can kill babies

• it can damage skin cells

• all of these

Two sheep would not be clones if

• they did not look exactly alike

• they did not grow up in the same place

• one of the sheep experienced high levels of radiation

• their nucleotide sequence was not the same
