The cell and inheritance
chromosomes and inheritance
grasshoppers have 12 pairs of chromosomes
1 chromosome from a pair comes from each parent
genes in chromosomes
alleles exist in pars in an organism
each one of the pair comes from a parent
genes are carried from parent to offspring on chromosomes.
grasshoppers body cells have 24 chromonomes
grasshoppers sex cells have 12 chromosomes
the process in which the number of chromosomes is reduced by half
what happens during meiosis
chromosome pair separate and distribute themselves to two other cells making half of the sex cell.
when creating an offspring the cell must have half from each parent so the offspring can have the normal amount of chromosomes.
meiosis and punnets squares
when the two chromosomes meet they both have an allele
the two alleles might be recessive, dominate, or both different
the dominant allele always coveres the recessive
a lineup of genes
the human body cell contains 46 chromosomes 23 from each parent
"chromosomes are made of genes joined together like beads on a string"
although you can only have 23 chromosomes they can contain 35000 genes- each gene controls a trait
