◉ dihybrid cross
Answer: cross involving two traits
◉ Mendel- four main principles
Answer: -alternative forms of genes are responsible for variation in
inherited characteristics
-the two alleles for each character segregate during gamete
production
-for each character, an organism inherits two alleles, one from each
parent
-if alleles of a gene differ, one is dominant and one is recessive
◉ Mendel's law of segregation
Answer: -pairs of alleles segregate during gamete formation
-allele pairs are restored during random fusion of gametes
,◉ test cross
Answer: cross individual with unknown genotype to homozygous
recessive
◉ Laws of Probability
Answer: -random events are independent of one another
-rule of multiplication
-rule of addition
◉ rule of multiplication
Answer: the probability that independent events will occur together
is the product of their individual probabilities
◉ rule of addition
Answer: the probability of an event that can occur in two or more
different ways is the sum of the independent probabilities of those
ways
◉ Mendel's Law of Independent Assortment
Answer: each allele pair segregate independently of other allele
pairs during gamete formation
◉ gene
, Answer: unit of heredity
◉ gene locus
Answer: place on the chromosome
◉ allele
Answer: form of a gene
◉ P generation
Answer: parent generation
◉ F1 generation
Answer: first generation of offspring
◉ F2 generation
Answer: second generation of offspring
◉ law of independent assortment
Answer: in a dihybrid cross, the alleles segregate independently
◉ pedigree
