Allele

Alternative forms of a gene for each variation of a trait of an organism

Dominant

Observed trait of an organism that masks the recessive form of a trait.

Fertilization

Fusion of male and female gametes

Gamete

Male and female sex cells,sperm and eggs

Genetics

Branch of biology that studies heredity.

Genotype

combination of genes in an organism

Heredity

Passing on of characteristics from parents to offspring.


Heterozygous

When there are two different alleles for a trait

Homozygous

When there are two identical alleles for a trait

Hybrid

Offspring formed by parents having different forms of a trait

Phenotype

Outward appearance of an organism regardless of its gene

Pollination

From male reproductive organs to female reproductive organs of plants,usually within the same species .

Recessive

Trait of an organism that can be masked by the dominant form of a trait.

Trait

Characteristics that is inherited can be either dominant of recessive

Zygote

Diploid cell formed when a sperm fertilizes an egg

Crossing over

Exchange of genetic material between consisted chromatids from homologous chromosomes during prophase I of meiosis ,results in New allele combinations

Diploid

Cell with two of each kind of chromosomes ,is said to contain a diploid ,or 2n ,number of chromosomes

Egg

Haploid female sex cell produced by meiosis

Haploid

Cell with one of each kind of chromosomes ,is said to contain a Haploid or n,number of chromosomes .

Meiosis

Type of cell division where one body cell produced 4 gametes ,each containing half the number of chromosomes as a parents body cell

Law of independent assortment

Mendelian principle staring that genes for different traits are inherited independently of each other.

Law of segregation

Mendelian principle explaining that because each plant has 2 different alleles,it can produce two different types of gametes.during fertilization ,male and female gametes randomly pair to produce four combinations of alleles.

Mitosis

Period of nuclear cell division in which two daughter cells are formed, each containing a complete set of chromosomes
