MODULE 1 Flashcards
The fundamental principles of inheritance
1
Q
Allele
A
a variant form of a gene
2
Q
Law of Segregation
A
Each organism has two alleles per gene, but only one is passed to offspring.
3
Q
Law of Independent Assortment
A
Alleles for different genes segregate independently during gamete formation.
4
Q
Appears in every generation (e.g., Huntington’s Disease).
A
Autosomal dominant
5
Q
Can skip generations (e.g., Cystic Fibrosis).
A
autosomal recessive
6
Q
More males affected (e.g., Hemophilia).
A
X-linked recessive
7
Q
Affected fathers pass to all daughters but never to sons.
A
X-linked dominant
8
Q
Predicting inheritance of genetic disorders (e.g., BRCA gene in breast cancer).
A
genetic counseling
9
Q
Used in agriculture (e.g., high-yield wheat, pest-resistant corn).
A
SELECTIVE BREEDING
10
Q
DNA analysis in crime investigations.
