chapter 3 Flashcards
what is hybridization?
mating of two distinct individuals that have different characteristics
what are hybrids?
offspring that result from such a mating
what is self-fertilization?
pollen and egg are derived from same plantwha
what is cross-fertilization?
pollen and eggs are derived from different plants
what is a single factor cross?
crossing variants that differed in only one character
what are monohybrids?
produces single character hybrids
how is the F1 generation created?
true breeding parents crossed to each other
how is the F2 generation created?
F1 generation is self-fertilized to produce the F2 generation
what is the theory of inheritance?
“units” are the determinants of genetic characters, exists in pairs and are inherited as discrete units that remain unchanged as they are passed down
what is mendels law of segregation?
during gamete formation, paired factors for a given character segregate randomly so that each gamete receives half of the factors
what are alleles?
different versions of the same gene
what does homozygous mean
an individual with two idential alleles- AA/aa
what does heterozygous mean?
an individual with two different alleles-Aa
