alien. They have 12 offspring. If purple is dominant over green, how many of the 12 offspring would you expect to be green?

Do a Punnett square to be sure!

Heterozygous Advantage

Chromosome Inactivation

Autosomal Recessive

Those persons with SS have a particular disease while those with AS do not show

the disease and in fact are more

resistant to another disease. What is this

referred to as?


Complete Dominance






Multiple Alleles


Autosomal Recessive

Some traits are governed by several

different genes. When this occurs,

we say it is this type of inheritance.


Complete Dominance






Multiple Alleles


Autosomal Recessive

The kind of inheritance like that

of a snapdragon, where the

heterozygous color is a blend of the dominant and

recessive colors.


Complete Dominance






Multiple Alleles


Autosomal Recessive

Some traits are governed by more than two possible versions of a gene. In this case, we say

the trait is controlled by...


Complete Dominance






Multiple Alleles


Autosomal Recessive

Some phenomena like that of the

calico cat are caused by expression of a

different chromosome in

different cells. This is known as...


Complete Dominance






Multiple Alleles


Autosomal Recessive

Which of the following states...

Principle of Dominance

Law of Segregation

Product Rule

Law of Independent Assortment

Gene-chromosome Theory

Chromosome Theory of Inheritance

The probability of two independent

events occurring together is the

product of their individual

probability of occurring alone



Law of Segregation

Product Rule




Mendel’s factors are genes carried on chromosomes; the

segregation and independent assortment of chromosomes during meiosis accounts for the patterns of inheritance



Law of Segregation

Product Rule




when individuals with contrasting

traits are crossed, the offspring will express only the dominant trait



Law of Segregation

Product Rule




genes exist at specific sites (loci)

arranged in a linear fashion along chromosomes



Law of Segregation

Product Rule




inherited traits are determined by pairs of "factors“ which separate in

the gametes, giving one in each gamete



Law of Segregation

Product Rule




if crossing over doesnot take place, genes that are located on

different chromosomes will assort

independently while genes that are located

on the same chromosome will be inherited together
