Flashcards in Heredity Deck (12):
1

1902

Theory proposed

Chromosomes are carriers of genes

2

Mutants

Carriers of genetic variant

3

Independent Assortment could not hold if

Chromosomes lined up in a specific order
I.e.
Paternal and maternal copies

4

Wild Type

Normal phenotype

5

X-linked inheritance

Genes connected to only the X chromosome

6

Linkage

Similar to crossing Over

7

Independent Assortment does not occur when genes are

Closer together in a chromosome

8

Crossing Over occurs more frequently in genes that are

Farther apart

9

Example:
2:2:1:1

Majority being those that don't cross over

10

In the XY system used by mammals this gene regulates the male state

SRY

11

How many X chromosomes work in males? Females?

One

12

The mechanism for x inactivation by the mother involves

Long lasting, transmissible changes in chromatin condensation
