1

What happens if an Autosomal Dominant Disorder has two dominant alleles

it is lethal

2

is Albinism recessive or dominant? What does it do

Recessive. defect of melanin that results in little pigment in skin and eyes

3

is Cystic Fibrosis recessive or dominant? What does it do?

Recessive. causes musuc buildup in lungs and/or digestive track. life-threating

4

2 sexes in one organism

9

what does diacious mean?

10

What is Mendel's Law of Indepent Assortmant

states that allele pairs separate independently during the formation of gametes. This means that traits are transmitted to offspring independently of one another.

11

What is Mendel's Law of Segregation

sates that allele pairs separate or segregate during gamete formation, and randomly unite at fertilization.

12

What is Mendel's Law of Dominance

states that one of the factors for a pair of inherited traits will be dominant and the other recessive, unless both factors are recessive.

13

Incomplete dominance

traits are blended (ex. red+white=pink)

14

c0-dominanat

both traits who up (Blood Type A+Blood Type B=BLood Type AB)

15

What happens in a higher crossover frequency

they are farther apart and have a higher chance of crossing

16

What happens in a lower crossover frequency

they are loser together and have a lower chance of crossing

17

Cell plate vs furrow

cell plate is made of cellulose

18

spindle fibers are made of what?

nicrofilaments
