Various forms of the same gene are called ________________________.
The spot on a chromosome where a particular gene is found is a ________________.
Pairs of matching chromosomes are called _______________________.
Organisms with two haploid sets of chromosomes are called ___________________.
All your chromosomes that are not sex chromosomes are ____________________.
Sex cells are called _______________________.
Body cells are called ____________________ cells.
An organism that has two copies of the same allele for a gene is ___________________
or also known as _______________________ .
An organism that has two different alleles for the same gene is
_____________________.
A cross between two true-breeding parents following the inheritance of only one genetic
locus is called a __________________ cross and when looking at two loci it is a
___________________ cross.
The first generation in either cross above is the ______ generation, the second generation
is the __________ generation and the third generation is the _______ generation.
The fact that the two alleles in a diploid organisms go into separate gametes during
gamete formation is called the Law of ________________________________________.
The fact that every pair of alleles (in Mendel’s experiments) separates as above, and does
so unaffected by every other pair of alleles is the Law of
___________________________________________
The physical traits of an individual are the ___________________, while the genetic
makeup is the _______________________.
When the phenotype of an individual is intermediate between that of the homozygous
dominant and the homozygous recessive then those alleles are said to exhibit
_______________________________________.
When both alleles are fully expressed in a heterozygote, then the alleles are said to be
_________________________________________.
When the presence of a dominant allele masks the presence of the recessive allele in a
heterozygote, this is a case of _________________________________.
When one locus has an effect on more than one character, even seemingly unrelated
characters, this is called _________________________.
When one character is affect by many multiple loci, this is called
____________________________.
When there are more than two alleles for a gene in a population, this is a case of
_______________________________________.
Polygenic characters vary along a __________________ and are also called
________________________ characters (rather than discrete). They are also affected by
the ________________________ and not just the genetic makeup of the individual.
In simple Mendelian Genetics (discrete characters, only two alleles with complete
dominance) monohybrid crosses produce an F2 generation with a phenotypic ratio of
______:________ and a genotypic ratio of ______homozygous dominant to _____
heterozygotes to _______homozygous recessive.
In a dihybrid cross, the phenotypic ratio will be _____:_____:_____:_____ if there is
independent assortment.
Humans do not adapt well to planned genetic experiments, so genetics in humans are
often analyzed using family __________________.
In pedigrees, circles represent _________________, squares represent ___________. A
horizontal line between a circle and a square represent _______________________. The
___________________ are listed below in birth order from left to right. The genetic trait
that is being followed in designated by a _____________ symbol.
Three recessive diseases that are fairly common in humans:
_____________________, ______________________ and ________________________
Three dominant disorders/traits that are fairly common in humans:
_____________________, ______________________ and ________________________
When events must occur simultaneously to produce a particular outcome we use the Rule
of _______________________________ to calculate the probability of that outcome
being produced.
When a particular outcome can come about in more than one way, we calculate the
probability of each independent way and then use the Rule of ____________________ to
calculate the probability of that the outcome will be produced.
In a mating where both parents are heterozygous, what proportion of their offspring are
expected to be heterozygous also? __________________
In a mating where one parent is heterozygous and one is homozygous recessive, what
proportion of their offspring are expected to be heterozygous? ___________________
When two genes are found on the same chromosome they are called ______________.
These genes will not assort independently and in a dihybrid cross there will be many
more ________________ types of offspring produced and many fewer ______________
types of offspring than would be expected from a similar cross when the genes are NOT
on the same chromosome.
