Branch of Biology that studies Heredity

Alternative form of a gene

Observable characteristics of an organism

The type of inheritance shown when a red flowering plant is crossed with a white flowering plant and only pink flowering plants are produced.

Heterozyogus alleles are also referred to as this.

Rod shaped structures where genes are located.

This blood type has the genotype of "i i"

This type of inheritance pattern is shown here.

The passing on of traits from parent to offspring.

Long wings is dominant to short wings

Stripes is dominant to spots.

What are the 4 possibe phenotypes if an insect that is heterozygous for both traits is crossed with an insect that is homozygous recessive for both traits.   

Tool used to predict possible offspring of a cross.

Single Trait Crosses

The color that will be inherrited by the offspring

This is the probability of producing a tall pea plant from a genetic cross between two hybrid tall pea plants

Trait 1: R-round , r-wrinkled

Trait 2: Green- G, yellow - g

What would the parent genotypes be if a wrinkled pea that is heterozygous for color is crossed with a pea that is heterozygous for shape and color.

Mendel used T to show the dominant allele for height, meaning tall. He used this letter to show the recessive allele

Trait of an organism that can be masked by the dominant form of a trait.

A heterozygous individual has one _________________ and one recessive allele.

A white mouse whose parents are both white produces only brown offspring when mated with a brown mouse. The white mouse is most likely _____________________    _____________________.

Green - G, Striped - g

Cross a homozygous dominant cucumber with a homozygous recessive cucumber. All of the offspring will have this genotype.

Name the man who is pictured here.

Nickname given to Gregor Mendel

Mendel's Rule of dominance states that one allele in a pair can _________________ the other.

Law of segregation states that a member of a pair of alleles seperates during ___________________________.

A dihybrid cross demonstrates this Mendelian principal

In rats, Black fur (B) is dominat to white fur (b) and long tait (L) is dominant to short tail (l). A rat that is heterozygous for color and homozygous for short tail is crossed with a white rat that is heterozygous for long tail. Show the cross and list the possible phenotypes of the offspring.
