are genes a concept or more concrete
concept
what are the 5 gene concepts
traditional, functional, regulatory, structural, evolutionary
what are character traits
physical appearance
what are traits
variation in character:brown/ blonde hair
definition of blending inheritance
offspring are a blend of essences from parents
particulate inheritance
offspring receive specific particles from their parents
Does Mendel’s pea experiment support blending or particulate inheritance
particulate
you get a 3:1 ratio from a ___ monohybrid cross
standard
did Mendel focus on ratios
no
Mendel noticed that gametes are __ and parents are __
haploid, diploid
term for each adult having 2 separate genes
diploid
term for each gamete carrying only one part of a pair of alleles
haploid
independent segregation/assortment
2 genes and their alleles will randomly assort into the gametes, produces 9:3:3:1 ratio
what ratio does dependent assortment create if you have 2 genes
3:1
in which assortment will the F2 generation show the same pattern as the parents
dependent assortment
Mendel laws are similar to physical laws becuase
genes and alleles were shown to be independent
Mendel was the basis for __
hardy-weinburg
a recessive pedigreee is looked at those who produce the
recessive trait
pedigrees are used in assigning
genotypes
proof of chromosomal existence came through working with __ __
fruit flys
chromosomes were shown to exist through showing in fruit flys that __ ___ mutations are __ linked
eye color, sex
fruit flys became the animal modal because we know that what Mendel found to happen in __ happens with __
plants, animals
Morgan’s experimental fly modal was an eye color mutation from
red to white
flys were used to show that ____ ___ was correct and how it could happen
chromosomal theory
doing a reciprocal cross with the flys produced
the same result
the reciprocal cross done with the flys helped to uncover if something is __ __
sex linked
