inheritance

Question 1

• Inherited

Answer 1

inherited refers to a trait or variants encoded in DNA and passed from parent to offspring during reproduction

Question 2

• Genetic trait

Answer 2

traits can be classified as inherited traits, which are passed from parents to offspring, or acquired traits, which develop through environmental influences. Genetic traits can be qualitative (like eye color) or quantitative (like height)

Question 3

Simple inheritance

Answer 3

Simple inheritance refers to the inheritance of traits controlled by a single gene with two alleles.

Question 4

Chromosome

Answer 4

A chromosome is a structure within cells that contains DNA and proteins.

Question 5

DNA

Answer 5

DNA is a molecule that contains the instructions an organism needs to develop, live and reproduce.

Question 6

Ovum (egg)

Answer 6

Female reproductive cell

Question 7

Sperm

Answer 7

reproductive organism that males produce

Question 8

Fertilization

Answer 8

fusion of gametes to give rise to a new individual organism or offspring and initiate its development

Question 9

x chromosome

Answer 9

The X chromosome is one of the two sex chromosomes in humans (the other is the Y chromosome). The sex chromosomes form one of the 23 pairs of chromosomes in each cell. The X chromosome spans about 155 million DNA building blocks (base pairs) and represents approximately 5 percent of the total DNA in cells.

Question 10

y chromosome

Answer 10

The X chromosome is one of the two sex chromosomes in humans (the other is the Y chromosome). The sex chromosomes form one of the 23 pairs of chromosomes in each cell. The X chromosome spans about 155 million DNA building blocks (base pairs) and represents approximately 5 percent of the total DNA in cells.

Question 11

• Variation

Answer 11

a Change in the regular cycle

Question 12

gene

Answer 12

In biology, the word gene has two meanings. The Mendelian gene is a basic unit of heredity.

Question 13

allele

Answer 13

each of two or more alternative forms of a gene that arise by mutation and are found at the same place on a chromosome.

Question 14

• Homozygous

Answer 14

the genetic condition where an individual inherits the same alleles for a particular gene from both parents.

Question 15

• Heterozygous

Answer 15

inherited different versions (alleles) of a genomic marker from each biological parent.

Question 16

Dominant

Answer 16

Dominant refers to the relationship between two versions of a gene. It is a term used in genetics to describe an allele, a gene, or a trait that is expressed and masks the effect of the recessive allele, gene, or trait when present

Question 17

ressesive

Answer 17

relating to or denoting heritable characteristics controlled by genes which are expressed in offspring only when inherited from both parents. Often contrasted with dominant

Question 18

Genotype

Answer 18

The genotype of an organism is its complete set of genetic material.

Question 19

phenotype

Answer 19

observable trait of an individual, such as height, eye color, and blood type

Question 20

• Punnett Square

Answer 20

A Punnett square is a diagram used in genetics to predict the genotypic and phenotypic outcomes of a genetic cross.

Question 21

• Co-dominant

Answer 21

Two alleles of a gene are both expressed in the phenotype, resulting in a combined, distinguishable trait

Question 22

• Incomplete dominance

Answer 22

both alleles of a gene at a locus are partially expressed, often resulting in an intermediate or different phenotype.
