transmission of traits from one generation to the next is called |
inheritance or heredity |
|
|
inherited similarity but not all siblings are the same copy because of |
variation |
|
|
the scientific study of heredity and hereditary variation |
Genetics |
|
|
coded information in the form of hereditary units called |
genes |
|
|
reproductive cells |
gametes |
|
|
all cells of the body excluding the sex cells and their precursors |
somatic cells |
|
|
a genes specific location along the length of a chromosome is called the gene's |
locus |
|
|
a single parent passes copies of all its genes to its offspring without the fusion of gametes |

|
two parents give rise to offspring that have unique combinations of genes inherited from both parents |
sexual reproduction |
|
|
generation to generation sequence of stages in the reproductive history of an organism, from conception to production of its offspring |

|
|
a display of the chromosome pairs of a cell arranged by size and shape |
