Flashcards For Biology Unit 14

Front 1

Definition of Gene Definition of allele

Back 1

Factors that are passed from parents to offsprings are called Gene and the Alleles are the different Form Of Gene.

Front 2

Gregor Mendels Principle of Inheritance

Back 2

Individual characteristics are determined by factors that are passed from one parent generation to the next.

Front 3

Dominant vs Recessive Alleles

Back 3

Most likely outcome of the two alleles. The trait that was not expressed is the recessive

Front 4

Purebread vs HYBRID

Back 4

100%- generation after generation of the same identicle trait. Parents with different traits are considered Hybrid

Front 5

HOMOZygous vs HETEROZygous

Back 5

SAME SEX- Same Seed and Individual that offspring from different traits are HETEROZYGOUS

Front 6

Genotype vs Phenotype

Back 6

Genetic makeup of an individual, but the apperance or way the trait is expressed in an individual is the Phenotype

Front 7

"Short" is an example of Genotype or Phenotype

Back 7

Phenotype

Front 8

"tt" is an example of Genotype or Phenotype

Back 8

Genotype

Front 9

Gametes VS Fertilzation

Back 9

Gametes are formation of the Sex Cells and fertilization produces a new cell. Gametes seperates and fertilization brings it back together

Front 10

Traits

Back 10

The specific characteristics such as Height or color

Front 11

Mendels F1, F2, P1

Back 11

P1 PARENTAL or First Generation, F1- second generation, F2- is the third generation

Front 12

Genetics

Back 12

The scientist study of heredity

Front 13

Probability Vs. Punet Square (Expected vs Reserved Results)

Back 13

The likley hood that a particular event will occur. Punnet Square

Front 14

Incomplete Dominance

Back 14

Case in which a allele is not complety dominant over the other. BLENDING

Front 15

Codominance

Back 15

Case phenotype are clearly expressed. An example of this a chicken with black feathers is Co Dominant with alleles for White Feathers. BOTH APPEAR

Front 16

Multiple Alleles (Blood Group)

Back 16

A gene with more than two alleles are said to have multiple alleles

Front 17

Apply Mendels Principles

Back 17

???

Front 18

Genetics and Environments

Back 18

When the environment has a role in how the gene determines the traits. Western white butterfly is an example that the environment CAN effect the PHENOTYPE or gene expression.

Front 19

Meiosis

Back 19

In the diploid cells of most adult organisms contain two complete sets of genes.
