Chpter 15.1 mendelian Inheritance has its physical basis in the behavior of chromosomes

Question 1

Mendel’s term for gene

Answer 1

hereditary factors

Question 2

THE CHROMOSOME THEORY OF INHERITANCE

Answer 2

According to this theory Mendelian genes have specific loci ( positions) along chromosomes , and it is the chromosomes that undergo segregation and independent assortment.
. a specific gene is carried on a specific chromosome e.g. eyecolor gene on the x chromosome.

Question 3

THE LAW OF SEGREGATION

Answer 3

The 2 alleles for each gene separate during gamete formation ( Homologous pair)

Question 4

THE LAW OF INDEPENDENT ASSORTMENT

Answer 4

Alleles of genes on honhomologous chromosomes assort independently during gamete formation

Question 5

WILD TYPE

Answer 5

The phenotype for a character most commonly observed in natural populations

Question 6

MUTANT

Answer 6

Opposite of wild type:

Question 7

What 3 processes of chromosomes lead to genetic variation

Answer 7

.independent orientation of chromosomes in meiosis
.crossing over of chromosomes in meiosis
.random fertilization
