CHROMOSOMES-
a tightly wound bundle of DNA and proteins found in the nucleus of most
living cells

GENES-
the basic unit of heredity in a living organism; a segment of DNA or RNA

GENOTYPE-
internal genetic coding passed on from one generation to the next

8.
Genetic Factors-
Genetic factors are used to study how a disease progresses through a family or population by
looking at if there is a specific genetic composition to the disease

ALLELES-
One member of a pair or series of genes on specific chromosomes in
specific positions

of a given cross

Purebred (Homozygous)-
Having identical alleles at one or more loci in homologous chromosome
segments

12.
Hybrid (Heterozygous)-
Having two alleles that are different for a given gene

13.
Dominant Trait (T- represented by a capital letter)-
A genetic trait passed from parent to child that is more likely to be expressed

14.
RECESSIVE TRAIT (T- REPRESENTED BY A LOWER CASE LETTER)-
A genetic trait that lacks the ability to manifest itself when a
dominant gene is present

WHERE CHROMOSOMES ARE FOUND...
Chromosomes are found in the nucleus.

CHROMOSOMES ARE MADE OF DNA, WHICH IS MADE UP OF GENES
