enumerate 3 laws of genetics

A

-law of dominance
-law of segregation
-law of development assortment

15
Q

he created the punnett square

A

reginald crundall punnett

16
Q

used to predict the offspring phenotype

A

punnett square

17
Q

in 2 different alleles, dominant trait will mask the recessive trait

A

law of dominance

18
Q

AA

A

homozygous dominant

19
Q

Aa

20
Q

aa

A

homozygous recessive

21
Q

parents with 2 alleses for a gene will pass on one allele to each offspring

A

law of segregation

22
Q

two or more traits are inherited separately

A

law of independent assortmentnn

23
doesnt follow according to mendels laws
non mendelian inheritance
24
one allele is partially dominant over another allele resulting to blending of characteristics
incomplete dominance
25
one alle is neither dominant over the other allele resulting in full trait expression
codominance
26
more than 2 alleles control over 1 gene
multiple alleles
27
located on x,y chromosomes
sex-linked traits
28
observed mostly in one sex
sex- influenced traits
29
exoressed only in one sex
sex-limited traits
30
is a path. the way something goes arounf an object in space
orbit
31
a tiny particle comprises waves of electromagnetic radiation
photon
32
indivisible
atom
33
stationary state of lowest energy
ground state
34
when an electron temporarily occupies an energy state grater than its ground state
excited state
35
negative charge subatomic particle
