Flashcards in Genetics Deck (11):
1

A species is ...

A group of organisms that share similar characteristics and reproduce to form viable offspring

2

A hybrid organism is a result of ...

Mixing genomes of different organisms

3

Define inbreeding

When mixing genomes of organisms that are too closely related

4

What will inbreeding cause ?

A decrease in hybrid vigor. Decreased heterozygosity and increased homozygosity

5

What did Gregor Mendel think about genetics ?

Genes were traits. Offspring received genes from each parent

6

What were mendels 3 principles

Dominance
Segregation
Independent assortment

7

Explain gonosomal inheritance

We inherit our genes or traits from our parents

8

Name a few sex linked diseases

Hemophilia.
Color blindness
Muscular distrophy

9

Why are men more susceptible to sex linked diseases

The Y chromosome has no alleles to compensate for X chromosomes faults

10

Why do only women have mitochondrial DNA ?

The zygote only inherits mothers mtDNA because males only contribute nuclear DNA and no mtDNA

11

How can we manipulate the genome

By genetic engineering
