Inteheritance

Question 1

Allele

Answer 1

An alternative form of a single gene

Question 2

Trait

Answer 2

A characteristic that a gene produces

Question 3

Phenotype

Answer 3

The observable characteristic or outward expression

Question 4

Genotype

Answer 4

The pair of alleles

Question 5

Recessive

Answer 5

Alleles that are masked in the f1 generation but reappeared in the F2 generation

Question 6

Dominant

Answer 6

Alleles controlled the traits that appeared in the f1 generation

Question 7

Homozygous

Answer 7

2 of the same allele for the trait

Question 8

Heterozygous

Answer 8

1 of each allele for the trait

Question 9

Carrier

Answer 9

A heterozygous gene resulting in an allele that is masked but not expressed

Question 10

Incomplete dominance

Answer 10

The heterozygous organisms shows an intermediate phenotype between the two homozygous phenotypes

Question 11

Incomplete domance

Answer 11

The heterozygous organisms shows an intermediate phenotype between the two homozygous phenotypes

Question 12

Codominance

Answer 12

Both the dominant and recessive alleles are expressed in heterozygous individuals

Question 13

Sex linked inheritance

Answer 13

Traits controlled by genes located in the X chromosomes

Question 14

Polygenic inheritance

Answer 14

Arises from the interaction is multiple pairs of genes

Question 15

Pleiotropy

Answer 15

One gene affects multiple phenotypic characteristics
