What is genetics?
The study of heredity.
100

The passage of genetic instructions (traits) from parent to offspring and determines how a tiger may get his stripes?

heredity/inheritence

100
Reproduction that is not complex, budding, never involves the formation of gametes, identical?

asexual reproduction

100
Some genes can be hidden or covered up by another. These are considered to be-
Recessive
100

The phase where chromosomes line up along the center and attach to spindle fibers?

Metaphase

200
Where are genes located?
In the chromosomes
200

An example of a homozygous or "purebred"

BB, bb

RR, rr


200

Name two traits that could be inherited from a parent. 

What is: hair color, eye color, skin, height, freckles, widows peak. 

200

What is used to determine the outcome of genetic crossings.

Punnett Square

200

The phase where cells form a new nuclei and begin to split?

Telophase

300
What are the threadlike structures of DNA that carry genes called?
Chromosomes
300

Two alleles or genotypes that are not the same?

heterozygous and/ or hybrid

300

Reproduction that is complex (has genetic variation)?

Sexual Reproduction

300
A black chicken (BB) is crossed with a black chicken (BB). What percentage of offspring will be black?
100%
300

The time a cell is growing, replicating DNA and preparing for cell division? 

HINT: before mitosis and/or meiosis

Interphase

400

How are inherited traits passed from parents to offspring?

through genes and chromosomes during reproduction

400
The physical trait observed in an offspring is known as it's -
Phenotype
400
For some traits, only one copy of a particular gene is needed to show a given trait. These genes are referred to as-
Dominant
400
Having dimples is dominant (D). Not having dimples is recessive. (d) Both parents are heterozygous for the dominant trait. What percentage of the children will NOT have dimples?
25%
400

Phase where the center splits, pulled to each opposite sides by spindle fibers and chromosomes separate?

Anaphase

500
What do we call the genetic make up of the individual, represented by a set of letters?
Genotype
500
How many chromomsomes do humans have?
46 or 23 pair
500

Two dark brown rabbits have four offspring. Three of the offspring are dark and one is white. What does this tell you about the parents' genes for fur color? (geno/pheno)

Dark brown is dominant and white fur is recessive. Both parents are heterozygous.

500
Long ears are dominant (E) in rabbits. If one parent is homozygous dominant for the long ear trait and the other homozygours reccessive (e), what is the only possible genotype of the offspring?
Ee
500

Phase where chromosomes or chromatids line up on the equator and attach to spindle fibers?

Metaphase
