Mendel And Heredity

Question 1

Alternative forms of genes

Answer 1

Allele

Question 2

Allele that is the most often expressed in an organism

Answer 2

Dominant

Question 3

Allele that is expressed only when a dominant allele is not present

Answer 3

Recessive

Question 4

Alleles that are identical to each other

Answer 4

Homozygous

Question 5

Alleles that are different from each other

Answer 5

Heterozygous

Question 6

holds that one from the pair of alleles coding for a particular trait would be expressed whereas the other is unexpressed. The allele expressed for a particular trait is regarded as the dominant whereas the other is considered recessive.

Answer 6

Law of dominance

Question 6

each member of a pair of homologous chromosomes separates independently of the members of other pairs so the results are random

Answer 6

Law of independent assortment

Question 7

allele pairs separate during gamete formation, and randomly unite at fertilization.

Answer 7

Law of segregation

Question 8

any pair of genes that tend to be transmitted together

Answer 8

Linked genes

Question 9

The set of observable characteristics of an individual resulting from the interaction of its genotype with the environment.

Answer 9

Phenotype
