Genetics

Question 1

Genetics

Answer 1

Study of biological inheritance

Question 2

Each gamete only has

Answer 2

one set of chromosomes

Question 3

Traits =

Answer 3

a specific characteristic of an individual

Question 4

Mendel’s Experiment

Answer 4

Crossing of two pea plants in order to study genetics

Question 5

Genes

Answer 5

DNA that determines a trait, passed on from parents to offspring.

Question 6

Alleles

Answer 6

Forms/Variations of the same gene

Question 7

Genotype

Answer 7

The two alleles genetic makeup

Question 8

Phenotype

Answer 8

The traits being expressed

Question 9

Law of Dominance

Answer 9

Mendel’s Law of Dominance states that when two different alleles for a trait are present, the dominant allele is expressed, while the recessive allele is masked unless both alleles are recessive.

Question 10

Homozygous Dominant

Answer 10

Both alleles given by mommy and daddy are dominant

Question 11

Homozygous Recessive

Answer 11

Both alleles given by mommy and daddy are recessive

Question 12

Heterozygous

Answer 12

One allele is Dominant and one allele is Recessive

Question 13

Mendelian Genetics

Answer 13

Only if there are two possible outcomes for alleles. Very simple

Question 14

Non-Mendelian Genetics

Answer 14

If there are blends, combinations, or more than two outcomes.

Question 15

Dominant Alleles

Answer 15

Dominant Alleles will be expressed if they are present in the genotype

Question 16

Recessive Alleles

Answer 16

Recessive Alleles will be expressed only if both mom and dad give a recessive allele.

Question 17

P

Answer 17

Parental generation

Question 18

F1

Answer 18

First Filial Generation

Question 19

F2

Answer 19

Second Filial Generation

Question 20

Monohybrid Cross

Answer 20

One gene is responsible for the trait

Question 21

Law of Independent Assortment

Answer 21

genes for different traits can segregate independently during the formation of gametes, therefore causing offspring with genetic diversity and not fixed genotypes.

Question 22

Dihybrid Cross

Answer 22

Two genes are present in the crossing

Question 23

Incomplete Dominance

Answer 23

One allele is not completely dominant over the recessive: This results in mixed results of the two alleles.

Question 24

Co-dominance

Answer 24

phenotypes produced by both alleles are clearly expressed. Both dominant and recessive are shown.

Question 25

Mulitiple Alleles

Answer 25

More than two alleles for one gene

Question 26

Blood Types are

Answer 26

Multiple Alleles and Codominance

Question 27

Polygenetic traits

Answer 27

Traits controlled by multiple genes

Question 28

Sex Linked Inheritance

Answer 28

Inheritance patterns linked to sex chromosomes

Question 29

Pedigrees

Answer 29

The recorded ancestry of a gene

Question 30

Autosomal Chromosomes

Answer 30

Chromosomes that are not the X and Y sex chromosomes

Question 31

Why are there sometimes different patterns of inheritance in males and females?

Answer 31

Because some disorders are coded on sex chromosomes, which varies based off of sex.

Question 32

X-linked Inheritance

Answer 32

Inheritance of traits on the X sex chromosome

Question 33

Genes on Y are

Answer 33

passed on from father to son, only on males

Question 34

In X-linked inheritance in males, men only need ___ in order to express it.

Answer 34

One allele, regardless of dominance or recessiveness, as men only have one X chromosomes.

Question 35

Therefore, it is statistically more common for who to have x-linked inheritance expressions?

Answer 35

Males
