ch 4 science

science ch 4

the basic form of heredity; indicates the traits or characteristics found or displayed by an individual genes
includes an individual's traits that are passed down from parents heredity
condensed DNA; each has several genes chromosomes
genetic material that is passed down form parents to offspring DNA
a pair of chromosomes, may have alleles homolog
the two different copies of the same gene alleles
where the genes are found on the chromosome loci
the genotype has two dominant alleles; shown in the phenotype when only one dominant copy is present homozygous dominant alleles
the genotype has two recessive alleles homozygous recessive alleles
a genotype that has one dominant and one recessive allele heterozygous allele
the names of genes that you cannot see; inherited form family genotype
an outward visible characteristic that genes are responsible for phenotype
used to determine the possible genotype of the resulting phenotype punnet square
the father of genetics Gregor Mendel
What our bodies use to fight off a virus? Antibodies
We inherit traits characteristics
simple outward characteristics, what you can see clearly qualitative
traits that you cannot see very clearly quantitive
Mendelian characteristics were ___________ traits qualitative
have half as many chromosomes as the parent cell gamete
cell division with 1 replication of chromosomes but with 2 divisions of cell producing gametes meiosis
determines the phenotype even when only one copy is present dominant gene
two copies must be present to be seen as the phenotype recessive gene
produced by meiosis; egg/sperm reproductive cells; 1/2 the number of chromosomes gametes
body cell division; daughter cell have the same number of chromosomes as the parent cell mitosis
combining of egg and sperm to produce offspring fertilization
pair of chromosomes homolog
produced from mitosis and the cells contain all chromosomes diploid
produced from meiosis and the cells contain 1/2 chromosomes haploid
