Heredity Flashcards
Trait
Characteristic that is inherited
Genetics
The study of heredity
Gamete
Male and female sex cells; sperm and eggs
Fertilization
male and female gametes coming together
Zygote
diploid cell formed when a sperm fertilizes an egg
Pollination
From male reproductive organs to female reproductive organs of plants
Hybrid
Offspring formed by parents having different forms of a trait
Allele
forms of a gene for each variation of a trait
Law of segregation
Mendelian principle explaining that each plant has 2 different alleles and male and female gametes pair to produce four combinations of alleles
Phenotype
physical appearance of an organism
Heredity
Passing on of characteristics from parents to offspring
Law of independent assortment
Principle founded by Mendel stating that genes for different traits are inherited independently of each other
Genotype
genetic code represented by two letters which are the alleles
what is the rule of unit factors
alleles and genes both determine traits of an organism
rule of dominance
dominant is observed, recessive is masked
