Mendel's Pinciples

Mendel's Pinciples--not including independent assortment

specific characteristics that vary among individuals traits
the offspring of true-breeding parents, possibly having different traits hybrid
factors that determine traits ( factors was Mendel's term for these) genes
sex cells, egg or sperm gametes
the different forms of a gene alleles
the form of the gene that is expressed ( if two factors are present and one of the factors is ___ it will be expressed) dominant
the form of the gene that is hidden or masked( this will only be expressed when two of these are present) recessive
Inheritance is determined by individual units called ____ genes
the individual units that determine inheritance are passed on from parents to offspring through the parent's _______ gametes
sexual reproduction includes the cell division process of ___ and the making of a diploid zygote by the process of ____ meiosis and fertilization
with traits that have more than one form such as peas that are yellow or green.. some forms of the gene are ____ and only one gene needs to be present to be expressed dominant
some forms of genes are ____ and can only appear when that organisms has 2 of them recessive
the only way to be recessive is two have two of the same genes or alleles which is called ____ ( use proper genetic term) homozygous
If the organism has 2 different genes such as Tt they are called ___( use the proper genetic term) heterozygous
In peas if T= tall and t = dwarf , and organism that if Tt will show the ____ form of the trait and be tall dominant
An individual has ____ (#) factor(s) per trait and gives ___# factor(s) per trait to their offspring 2 and 1
If an individual is described as having 2 traits, then its genotype should have ___(#) factors 4 ( 2 per trait)
The individual's factors that are described by pairs of letters for every trait is called the ___ genotype
When gametes are formed, the pairs of hereditary factors ____ so that each sex cell can donate 1 per trait separate
What is Mendel's law of Segregation when gametes are formed the genes that are in the parent separate to make the egg or sperm .. then when fertilization occurs the gene pair will unite in a NEW offspring for the next generation
