Which type of inheritance pattern is when there are two or more alleles for one gene?
multiple allele
Polygenic Trait
Incomplete Dominance
Linked genes
What type of inheritance is where there are two or more genes that code for a trait?
Multiple Allele
polygenic traits
linked genes
What are genes that are physically located on the same chromosome and typically inherited together?
Polygenic Traits
Multiple Allele
Linked genes
Genotypes
What is the only way for linked genes not to be inherited together?
If they independently assort away from each other
during synapsis
if they swap during crossing over
if nondysjunction occurs
What are traits that are found on the X chromosome called?
Multiple Allele
Polygenic Traits
Sex-linked Traits
Autosomes
If a mother is a carrier for a sex-linked disorder can she pass the trait on to her offspring?
yes
no
What is a person that is not affected or a carrier of a sex-linked trait called?
Normal
Affected
Carrier
A person
Why do males tend to be more affected by sex linked traits than females?
Males only have one X chromosome so if they inherit the disorder they will show it.
Males are carriers and therefore not affected.
Males have a Y chromosome that overshadows the X chromosome.
Females are immune to all sex-link disorders.
Which sex chromosomes does a female have?
XX
XY
YY
Which sex chromosomes does a male have?
XX
XY
YY
Which sex chromosome does a father pass on to his sons?
X
Y
In Labrador retrievers some puppies have pink noses and some have black. Most dogs that have black fur have black noses. Which inheritance pattern is this an example of?
Multiple Allele
Epistasis
Linked Genes
Sex-linked traits
Why can't men be carriers of sex-linked traits?
Because they only inherit one X
Because the Y is always dominant
Because they never inherit sex-linked traits
Drag the following trait from the scenario to the correct genotype:
A red flower is crossed with a white flower and the offspring are pink.
FF
Red
F'F'
White
FF'
Pink
Drag the following trait from the scenario to the correct genotype:
Sickle Cell anemia is inherited when you inherit a normal gene and an abnormal gene.
NN
Normal
AA
Abnormal
NA
Sickle Cell
Drag the sex-linked genotype to the correct phenotype:
