Genetics Flashcards
A species is …
A group of organisms that share similar characteristics and reproduce to form viable offspring
A hybrid organism is a result of …
Mixing genomes of different organisms
Define inbreeding
When mixing genomes of organisms that are too closely related
What will inbreeding cause ?
A decrease in hybrid vigor. Decreased heterozygosity and increased homozygosity
What did Gregor Mendel think about genetics ?
Genes were traits. Offspring received genes from each parent
What were mendels 3 principles
Dominance
Segregation
Independent assortment
Explain gonosomal inheritance
We inherit our genes or traits from our parents
Name a few sex linked diseases
Hemophilia.
Color blindness
Muscular distrophy
Why are men more susceptible to sex linked diseases
The Y chromosome has no alleles to compensate for X chromosomes faults
Why do only women have mitochondrial DNA ?
The zygote only inherits mothers mtDNA because males only contribute nuclear DNA and no mtDNA
How can we manipulate the genome
By genetic engineering
