Gen Vol 2 Eh Eh Eh Flashcards
Allele
Version of a gene/ trait
Dominant allele
Shows up
Recessive allile
Is hidden
Generations terms
P- parent generation
F1 - first filial generation
F2 - 2nd filial generation
Cross sibs
Cross between siblings from the same parents
Backcross
Parent crossed with an offspring
Self cross
Crosses with its self or genetic twin
True breeding
Homólogos chromosomes
Locus
Location (where is it found? Which part of the chromosome which chromosome)
Wyldetype allile
Allile that show up the most in a population
Mutant allele
Most rare version of the allele
Reciprocal cross
When you switch genders
So for example you have
Red hair dad and a brown hair mom and you switch to brown hair dad and red haired mom p
Test cross
If one parent is receive
And all children come out dominate they are homogeneous
If some kids have 1/2 dominate and 1/2 recessive then parent is heterozygous
Phenotype
Physical apearence
Zygote
Diploid cell
Homozygote and heterozygous
Homo AA
Hetero Aa
And and or
And is x
Or is +
Codominate
Mixture of the the two allile s ink like either of the parents
One is more then the other more splotchy or dots
Incomplete dominate
Neither is dominate
So is mixture of the two
Entirely new
How many chromosomes are in a human healthy
46
All genes are for the most part very similar with little deviation
Karyotype
Picture of chromosomes laid out from tallest chromosome 1 to shortest chromosome 22 (21 is actually shorter the 22) and then the sex chromosomes
Autosomal chromosomes
1-22
Same in both men and women
Carry female sex characteristics
Along with the X chromosome
Sex chromosomes
X and Y
Y Carrie’s male characteristics which is about 50 genes (ex testosterone)
Number disorder
Remember they double before mitosis
Based on amount of chromosomes
