mendelian genetics

Question 1

what are the main types of mendelian genetics

Answer 1

complete dominance, incomplete dominance, codominance, sex linked traits, multiple alleles

Question 2

what is complete dominance

Answer 2

when the dominant gene takes over (cancels out) the recessive gene

Question 3

what is incomplete dominance

Answer 3

when the two genes cross and create a blend of the phenotypes

Question 4

what is codominance

Answer 4

when both alleles in a heterozygous individual are fully expressed, example spots, stripes, flower petal colors, sickle cell anemia

Question 5

what is sex linked traits

Answer 5

charecteristics determinidn by genes located on the sex chromosomes.

Question 6

what is multiple alleles

Answer 6

multiple alleles refers to a situation where a gene has more than two alleles for a trait.

Question 7

what is homozygous

Answer 7

when both alleles are the same either dominant or reccesive

Question 8

what is heterozygous

Answer 8

when there’s two different alleles either Pp or pP

Question 9

what is the foil method

Answer 9

a method used to multiply genotypes to create a punnent square

Question 10

what does the letters in FOIL stand for

Answer 10

first, outer, inner, last

Question 11

who created mendelian genetics

Answer 11

Gregor Mendel

Question 12

what are reccesive traits

Answer 12

traits that can skip a generation

Question 13

what are dominant traits

Answer 13

traits that don’t skip a generation

Question 14

what’s the p1 generation

Answer 14

when u cross the same allelles
RRxRR

Question 15

whats the F1 generation

Answer 15

when u cross contrasting typed of alles
RRxWW

Question 16

what’s the f2 generation

Answer 16

RWxRW

Question 17

what is epistasis

Answer 17

an effect of when one gene at one locus can mask or modify the expression of another gene.

Question 18

what is pleiotrophy

Answer 18

when one gene affects multiple seemingly unrelated phenotypic traits. like a tissue gene that causes red hair and long toes examples- sickle cell anemia, albinism

Question 19

what is polygenic traits

Answer 19

the control of a trait by more than one gene often resulting in a lot of possible phenotypes.

Question 20

what is epigenetics

Answer 20

the study of changes in gene expression without actually changing the gene DNA. think likehow nature and a persons enviroment.

Question 21

who was Charles darwin

Answer 21

proposed the idea of evoulution

Question 22

what is an allele

Answer 22

alternating forms of a gene one from mom one from dad

Question 23

what’s the blending theory assosciated with

Answer 23

incomplete dominance

Question 24

what is codominance assosciated with

Answer 24

roan cattle with thetre hair, sickle cell anemia

Question 25

true or false dominant traits are more common than reccesive

Answer 25

false

Question 26

why is it more common for males to have colorblindness

Answer 26

because they only have to have it on one allele Wich is more common

Question 27

what does the p generation mean

Answer 27

purebred

Question 28

what is codominiance

Answer 28

both traits are expressed in a phenotype

Question 29

is a chromosome a form of dna

Answer 29

yes

Question 30

what does the foil method (creating the most combinations of a genotype) symbolize

Answer 30

meiosis

Question 31

what is meiosis

Answer 31

creating diversity in sex chromosomes

Question 32

what are homologous pairs

Answer 32

2 pairs of chromosomes with the same genes butt different alleles that code for the same trait

Question 33

what are chromosones 1-22 called

Answer 33

autosomes

Question 34

what are chromsones 23 called

Answer 34

sex chromosomes

Question 35

2

Question 39

how many letters is an allele

Answer 39

1

Question 40

what does polygenic mean

Answer 40

multiple genes for 1 trait

Question 41

what is epistasis

Answer 41

when one gene covers up another gene next to it

Question 42

what are epigenetics

Answer 42

things that determine your nature outside of ur genetics

Question 43

what's dihybrid genetics mean

Answer 43

heterozygous for both traits

Question 44

what's hybrid mean

Answer 44

an organism that has two different alleles for a trait. aka heterozygous

Question 45

what is incomplete dominance also known as

Answer 45

intermediate inheritance7
