Genetics🧬🧪

Question 1

Genetics

Answer 1

The field of biology that studies how characteristics are passed from parent to offspring

Question 2

Alleles

Answer 2

The contrasting form of a gene there are at least two for every trait. These are representing with letters (AA,Aa,aa)

Question 3

Dominant allele

Answer 3

The trade that shows up when it is present represented by the capital letter A

Question 4

Recessive allele

Answer 4

The trait that shows up only when the dominant alleles is not present, represented by the lowercase letter (a)

Question 5

Genotype

Answer 5

The genetic makeup of an organism, the combination of all alleles written i letter form(TT,Tt,tt)

Question 6

Phenotype

Answer 6

The PHYSICAL appearance of an organism (yellow,green,tall)

Question 7

Homozygous

Answer 7

The condition in which both alleles are the same, also called pure breed(AA,aa)

Question 8

Heterozygous

Answer 8

The condition in which that alleles are different, also called hybrid(Tt)

Question 9

Test cross

Answer 9

Procedure in which an individual with an unknown genotype is crossed with an individual that is recessive to determine the genotype of the unknown

Question 10

Incomplete dominance

Answer 10

A type of genetic pattern in which one allele is not completely dominant over the other that results in blending of physical traits example :white mixed with black makes gray

Question 11

Codominance

Answer 11

A genetic pattern where both alleles are expressed and contribute to the phenotype both traits are physically visible together, black and white mixed results in spotted speckled or striped black-and-white appearance

Question 12

Multiple-alleles

Answer 12

A genetic pattern in which there are more than 2 alleles for a particular trait

Question 13

Sex-linked traits

Answer 13

A genetic pattern in which genes are found on the X or Y chromosome (often referred to sex-linked traits when found on the X chromosome)

Question 14

Polygenetic traits

Answer 14

A genetic pattern in which the trait is controlled

Question 15

Blood type

Answer 15

A human example of a multiple allele, codominant trait

Question 16

Heredity

Answer 16

The passing on a characteristics as the (color of the eyes or hair) from parents to offspring

Question 17

Punnet square

Answer 17

Is square diagram that is made of a grid of usually four boxes and is used to calculate all the combinations and frequencies of the different genotypes and phenotypes among the offspring
