The scientific study of heredity and hereditary variation.
a genetically determined characteristic
a strand of DNA that carries the genes in a specific order
segments of DNA that carry the instructions for traits that are passed from parents to offspring (kids)
a copied section of DNA that helps make proteins in the cell
Human Genome Project
the goal of this is to determine the job of each of the genes located on the 23 pairs of human chromosomes
the study of the impact of technology and science on human society
the passing of traits from parents to offspring (kids)
each gene in a pair of genes
a table that can be used to predict what traits offspring will have based on the traits the parents have
the set of alleles an organism has for a trait
an organism's appearance
the chance that something will happen
a permanent change in the DNA sequence that makes up a gene
a technology in which the genome of a living cell is modified (changed)
the genetic material found in a cell's nucleus
a trait that is passed on from one generation to the next ie. a feature that is coded for in genes of DNA.
(ex. freckles or not)
inheritance of sex
males are xy females are xx so it is the male Y gamete that forms male offspring when fertilizing one of the female X gametes
non inherited characteristic
a trait that is not passed on from one generation to the next ie. a feature that is not coded for in genes of DNA. eg scars.piercings, dyed hair
The sum of all chromosomes in a cell of a given type. 46 in body cells of humans. 23 in a sex cell.
red blood cell
_______________ has 0 chromosomes as it does not have a nucleus
the human male gamete the _______________ has 23 chromosomes ,
____________ is a fertilized egg. It is a single diploid (2N) cell. A diploid cell contains a set of chromosomes from each parent cell.
