The scientific study of heredity (inherited characteristics)
Biology
Embryology
Genetics
Ecology
The process of a male and female gamete coming together to create the zygote.
crossing over
fertilization
segregation
inheritance
An expressed characteristic of an individual that is determined by genes.
chromosome
DNA
genotype
trait
The offspring of parents with different traits is called a:
hybrid
clone
homozygous genotype
gamete
A segment of DNA that codes for a protein and determines a trait.
nucleotide
gene
chromosome
phenotype
Different varieties of a gene. Example: Black, white, gray, brown fur color.
chromosomes
chromatids
alleles
gametes
Mendel's principle of dominance:
The more successful traits are always dominant.
All alleles have equal chance of being expressed.
Some alleles are dominant over others and will be expressed when combined with recessive alleles.
A single allele can switch back and forth between being dominant and recessive.
The separation of alleles during gamete formation (meiosis):
segregation
crossing over
incomplete dominance
fertilization
Sex cells are called:
Somatic
Gametes
Diploid
Sex chromosomes
The genetic makeup of an organism (which alleles it has):
Blood type
Phenotype
Genotype
Characteristics
Having the same 2 alleles for a gene (YY or yy)
Homozygous
Heterozygous
Homologous chromosomes
Autosomes
Having a genotype with two different alleles for the gene (Yy)
Homozygous
Heterozygous
