4x more wool production

Front (Question)

what is the effect of genetic manipulation on egg production?

Back (Answer)

from 15 eggs/yr with jungle fowl to 250 eggs/yr with white leghorns

Front (Question)

what is the effect of genetic manipulation on broilers?

Back (Answer)

went from 12 wks to 56 days to mature

Front (Question)

what is the effect of genetic manipulation on turkey?

Back (Answer)

AI is now required for reproduction due to selection for breast meat (white v. dark)

Front (Question)

what is the effect of genetic manipulation on beef cows?

Back (Answer)

little change in production overall

Front (Question)

what is the effect of genetic manipulation on horses?

Back (Answer)

no change in speed index in last 40 yrs, but through selection, genetic diseases are more prevalent

#10

Front (Question)

what is the effect of genetic manipulation on dogs and cats?

Back (Answer)

genetically tortured, very specific selection = lots of disorders and physiological problems

#11

Front (Question)

what is the equation for genetic phenotype?

Back (Answer)

P = G + E, phenotype = geneotype + environment

#12

Front (Question)

what three things control genotype?

Back (Answer)

genes, DNA, chromosomes

#13

Front (Question)

define gene

Back (Answer)

a DNA sequence on the chromosome that codes for a biologically important molecule

#14

Front (Question)

what does DNA stand for?

Back (Answer)

deoxyribose nucleic acid

#15

Front (Question)

define chromosome

Back (Answer)

one of a number of long stands of DNA and associated proteins present in the nucleus of every cell

#16

Front (Question)

how is gene expression determined in animals?

Back (Answer)

Mendelian genetics; dominant and recessive genes

#17

Front (Question)

AA equals?

Back (Answer)

#18

Front (Question)

Aa equals?

Back (Answer)

#19

Front (Question)

aa equals?

Back (Answer)

#20

Front (Question)

what is incomplete dominance? give an example

Back (Answer)

a mix of both dominant and recessive genes; shorthorn cattle roan coat color

#21

Front (Question)

what is the importance and heterozygous and homozygous?

Back (Answer)

both genes have a 50/50 shot of being passed on

#22

Front (Question)

what are the types of traits?

Back (Answer)

qualitative, simply inherited, and quantitative, polygenic

Back (Answer)

discrete classes, yes/no, black/red

#24

Front (Question)

define simply inherited traits, give an example

Back (Answer)

few genes control trait color
