Meiosis and Heredity Flashcards
Meiosis
the process that makes egg and sperm
Gametes
the general term for reproductive cells
Fertilization
the union of egg and sperm
Crossing Over
occurs when homologous chromosomes exchange sections of DNA during meiosis
Haploid
a cell containing one chromosome from each pair of chromosomes
Homologous Pair
matching chromosomes // a pair of chromosomes that code for the same trait
Diploid
a cell containing both chromosomes from each pair of chromosomes
Heredity
passing of traits from parents to offspring
Genes
the section of DNA that codes for a trait
Alleles
a variation of a gene
Genotype
the genetic make-up of a trait
Phenotype
the physical appearance of a trait
Zygote
the cell created from the union of egg and sperm
Heterozygous
if the alleles are different; ex. (1,2)
Homozygous
if the alleles are the same; ex. (2,2)
