Laws of Inheritance

Question 1

What is a dominant allele?

Answer 1

An allele that, whenever present, will always be expressed

Question 2

What is a recessive allele?

Answer 2

An allele, where if the dominant allele isn’t present, the recessive allele will be expressed

Question 3

Each characteristic contains how many alleles? and how are dominant and recessive alleles represented?

Answer 3

1. Each characteristic contains 2 alleles from each parent
2. A = Dominant, a = Recessive

Question 4

What are heterozygotes?

Answer 4

Refers to a genotype having different types of alleles

Question 5

What is Homozygote Dominant?

Answer 5

Refers to a genotype having dominant alleles only

Question 6

What is Homozygote Recessive?

Answer 6

Refers to a genotype having recessive alleles only

Question 7

What is the definition of Genotype?

Answer 7

Genetic composition of an organism

Question 8

What is a Phenotype?

Answer 8

Set of observable traits of an organism

Question 9

List Mendel’s 3 laws of Inheritance

Answer 9

1. Law of Dominance: A trait will try to conceal another trait in Heterozygotes
2. Law of Segregation: Two alleles equally separate into four gametes (Gamete is when two Haploids combine)
3. Law of Independent Assortment: Genes don’t influence each other
