Having two different alleles for a trait

heterozygous

The basic unit that makes up DNA. Consists of a phosphate group, a deoxyribose sugar, and a nitrogenous base.

nucleotide

sex cell formed in the female reproductive organs that contains half the number of chromosomes as body cells.

egg cell

sex cell formed in the male reproductive organs that contains half the number of chromosomes as body cells

sperm

All nucleotides contain which of the following?

sugar, phosphate, nitrogen base

A pair of nucleotides - either adenine-thymine linked together, or guanine-cytosine linked together.

nitrogen base pair

A chart that shows all possible combinations of alleles.

punnett square

An organisms genetic makeup, or allele combinations

genotype

Cell division where the chromosomes in a cell nucleus are separated into two identical sets of chromosomes, each in its own nucleus.

mitosis

Cell division that halves the number of chromosomes when forming sex cells

meiosis

Any chromosome that is not a sex chromosome

autosome or somatic

An allele that is masked when a dominant allele is present

recessive allele

Aa x Aa

25% AA, 50% Aa, 25% aa

aa x AA

0% AA, 100% Aa, 0% aa

trace phenotypes in families and reveal modes of inheritance.

pedigree

XX is what gender?

female

unites gametes and restores the diploid number producing the first cell of the next generation

fertilization

the passing of traits from parents to offspring

heredity

AA x Aa

50% AA, 50% Aa, 0% aa

Chromosomes with similar length, similar positions of centromeres, and similar loci (locations of genes).

homolgous chromosomes

both alleles of a gene are present in the phenotype

codominance

A cell containing both sets of chromosomes

diploid

An allele whose trait always shows up in the organisms when the allele is present

Dominant allele

Coiled chromatin, 46 are found in human body cells

chromosome

A blended phenotype. One allele is not completely dominant over the other

incomplete dominance

when traits are determined by alleles on the sex chromosomes

sex-linked

A visual depiction of the number, size and shape of chromosomes found in a cell of an organism.

karyotype

The physical traits that appear in an individual as a result of its genotype

phenotype

The different forms of a gene

Allele

a cell containing only one set of chromosomes - gametes

haploid

DNA sugar

deoxyribose

Having two identical alleles for a trait

homozygous
