Vocab flipped Flashcards
Mendelian principal explaining that because each plant has two different alleles, it can produce two different types of gametes. During fertilization, male and female gametes randomly pair to produce four combinations of alleles
Law of segregation
when there are two different alleles for a trait
heterozygous
characteristic that is inherited; can be either dominant or recessive
trait
transfer of male pollen grains to the pistil of a flower
pollination
alternative forms of a gene for each variation of a trait of an organism
Allele
passing on of characteristics from parents to offspring
heredity
major source of genetic variation among organisms caused by re-assortment or crossing over during meiosis
Genetic recombination
fusion of male and female gametes
fertilization
offspring formed by parents having different forms of a specific trait.
hybrid
when there are two identical alleles for a trait
homozygous
combination of genes in an organism
genotype
Mendelian principal stating that genes for different traits are inherited independently of each other.
Law of Independent Assortment
pattern of reproduction that involves the production of subsequent fusion of haploid cells.
sexual reproduction
failure of homologous chromosomes to separate properly during meiosis; results in gametes with too many or too few chromosomes
nondisjunction
trait of an organism that can be masked by the dominant form of a trait
recessive
