Mono hybrid inheritance

Question 1

Define Inheritance

Answer 1

the passing on of genetic information from one generation to the next.

Question 2

Define trait

Answer 2

a distingushing quality or characteristic

Question 3

Define Gene

Answer 3

genetic information which is transferred from a parent to offspring in the chromosomes

Question 4

Define allele

Answer 4

Is one of the possible form of a gene

Question 5

define heterozygous

Answer 5

When an organism has two different alleles for a certain characteristic

Question 6

Define homozygous

Answer 6

When an organism has two identical alleles

Question 7

Define dominant

Answer 7

Traits that are always expressed (visible in the organism )

Question 8

Define reccesive

Answer 8

Traits that are only seen when they are the only ones present ( the trait is marked )

Question 9

Define phenotype

Answer 9

the set of observable characteristics of an individual

Question 10

Define Genotype

Answer 10

the genetic make up of an organism

Question 11

Define punnet square

Answer 11

A diagram that is used to predict an outcome of a particular cross

Question 12

Define Monhybrid

Answer 12

The offspring of individuals that differ with respect to a particular gene

Question 13

Define Co Dominance

Answer 13

The dominant gene does not completely suppress the reccessive gene, allowing both genes to be diaplayed at the same time without any blending

Question 14

Define incomplete dominance

Answer 14

When a cross between an organism with two different phenotypes produce offspring with a third phenotype that is a blending of the parent

Question 15

Define sex linked disease

Answer 15

Are genetic disorders that through one of the sex chromosomes X or Y

Question 16

Define Haemophilia

Answer 16

A genetic disorder where blood clotting is impaired, leading to prolonged bleeding. The gene for hemophilia is located on the X chromosome, so it primarily affects males who inherit the affected X chromosome from their carrier mothers.

Question 17

Complete dominance

Answer 17

When the dominant allele completely covers up the recessive allele

Question 18

who are more likely to carry sex linked diseases

Answer 18

Since males have only one X chromosome (XY), they are more likely to manifest sex-linked disorders if they inherit the affected allele.

Question 19

Describe red color blindness

Answer 19

red-green color blindness, are caused by mutations in genes located on the X chromosome. This condition is more prevalent in males.

Question 20

Describe fragile X Syndrome

Answer 20

The most common inherited cause of intellectual disability, caused by a mutation in the FMR1 gene on the X chromosome. It affects both males and females, but males typically have more severe symptoms.

Question 21

Cleft palate

Answer 21

The roof of the mouth (palate) is formed between the sixth and ninth weeks of pregnancy. A cleft palate happens if the tissue that makes up the roof of the mouth does not join together completely during pregnancy.
