Chapter 12- Chromosomal Inheritance

Question 0

Wild Type

Answer 0

The normal type of chromosomes found in wild flies

Question 1

Chromosome theory of Inheritance

Answer 1

Mendelian genes have specific loci on chromosomes and their profit ion determines if they assort independently

Question 2

Answer 2

A Gene found on the X or Y chromosome

Question 3

X linked Gene

Answer 3

Genes found on the X chromosome and are more disability are found in men

Question 4

Duchenne Muscular Dystrophy

Answer 4

An x linked gene that affects 1 out of 3500 men and is progressive loss and weakening of muscles after the late 20’s

Question 5

Answer 5

X linked disorder when blood doesn’t clot

Question 6

Barr Body

Answer 6

When a gamete that is female one of each x in the cell activates and one deactivates randomly so there is a random number of each x’s

Question 7

Linked Genes

Answer 7

Genes that are close to each other on chromosomes inherited together in crosses

Question 8

Genetic recombination

Answer 8

The production of offspring that differ in traits than those found in either parent

Question 9

Parental Types

Offspring that matches the parents phenotypes

Question 10

Recombinants

Answer 10

Offspring that have different phenotypic combinations than their parents

Question 11

Crossing over

Answer 11

In meiosis when genes cross over and mix information
