Mendelian inheritance

1 / 12

13 Terms

1

Mendelian inheritance

autosomal dominant/recessive, rarest time of inheritance, doesnt involve sex cells, dicovered by Gregor Mendel

New cards
2

Law of segregation

during production of gametes, the alleles separate so that the offspring only acquire one of the alleles

New cards
3

Law of independent assortment

use probability to solve di-hybrid and poly-hybrid cross problems only if they DONT influence each other

New cards
4

Phenotype vs Genotype

Phenotype is a physical trait, Genotype is an allele/gene

New cards
5

Test cross

a method to determine the genotype of an organism that shows a phenotypically dominant trait

New cards
6

poly genetic inheritence

primary type of inheritance, phenotypes produced by interaction of more than one gene (height, hair color)

New cards
7

incomplete dominance

“blending”, heterzygotes show intermediate expression

e.g.

T = normal

D = defective

TT = normal TD = mild symptoms DD = extreme

<p>“blending”, heterzygotes show intermediate expression</p><p>e.g.</p><p>T = normal</p><p>D = defective</p><p>TT = normal  TD = mild symptoms  DD = extreme</p>
New cards
8

co dominance

both alleles are expressed e.g. blood type

New cards
9

sex-linked genes

phenotypic expression base don sex chromosomes

<p>phenotypic expression base don sex chromosomes</p>
New cards
10

pedigree

family tree that shows inheritance

<p>family tree that shows inheritance</p>
New cards
11

ways to determine inheritance from pedigree

skips generation = recessive

every generation = dominant

father →son = y-linked

mainly male = x-linked recessive

New cards
12

linked genes

genes on the same chromosome, DONT CONFUSE WITH SEX-LINKED

New cards
13

recombinant frequency

nonparental phenotype total/total, gives you the space between two genes on a chromosome

<p>nonparental phenotype total/total, gives you the space between two genes on a chromosome</p>
