1

What factors played a significant role in Mendel's success in developing the basic principles of inheritence?

proper experimental model, his approach and anaylzed results, studied easily differentialed characteristics

2

Medal worked with

peas... he looked at specific characters that could be easily differentiated.

3

homozygote

an individual organism possessing tow of the same alleles at a locus

4

heterozygote

an individual organism possessing tow different alleles ata locus

5

phenotype or triat

the apperance or manifestation of the characteristic

6

character

an attribute or feature

7

Genes exist in different veriosns called

alleles

8

each allele encodes different

characteristics

9

Different alleles for a particular gene...

occupy the same locus on homologus chromosmes

10

monohybride cross

a cross btw two parents that differ in a single characteristic

11

each individual diploid organism possesses two alleles for any particular characteristic. These two alleles segregate when gametes are formed, and on allele goes into each gamete

Principle of segregation (mendel's first law)

12

when two differetn alleles are present in a genotype, onyl the trait encoded by one of them, the dominant allele- is observed in the phenotype

the concept of dominance

13

segregation results from?

the separation of homologous chromosomes in meiosis

14

When does independent assortment occur?

anaphase I
