Monohybrid inheritance involves inheritance of _______ characteristics and __________ traits controlled by a gene.
Monohybrid inheritance involves inheritance of one characteristics and contrasting traits controlled by a gene.
Genes and alleles
Gene is a ___________ of inheritance which consist of__________ segment
Gene is a basic unit of inheritance which consist of DNA.
Gene and alleles
Allele is an __________ form of ______ for a trait.
Allele is an alternative form of gene for a trait.
Characteristics and traits.
Characteristics are__________
such as eye colors, blood type and hair color.
Heritable features
Traits are _________ of a ________ characteristic.
Variation; specific
What is the term use for observable characteristics?
Phenotype
What is the term use for genetic composition of an organism that cannot be seen?
Genotype
What is a dominant alleles and recessive alleles?
Dominant alleles shows its characteristics and suppresses the effects of recessive alleles
Recessive allele only shows its trait when both alleles are recessive alleles. Effects of recessive alleles is suppressed by the dominant alleles
What is the the difference between homozygote and heterozygote?
Both alleles at the loci of a pair of homologous chromosomes are the same
Heterozygote are alleles at loci of homologous chromosomes are different
Dominant trait is expressed when _______ alleles are ___________ or one _______ allele is paired to one________ allele.
Both alleles are dominant or one dominant allele is paired to one recessive allele
Recessive trait is expressed if a pair of _______ are paired together.
pair of recessive alleles
What is the definition of purebreeds?
Individuals that carry 2 identical alleles for a trait
What is the definition of hybrid?
Hybrid is the product of mating between 2 _________ varieties
Purebreed
Parential generations refers to the________ generation of two individuals which are mated to predict and analyse the ________ of their offspring.
Filial generation refers to the_________ generation as a result of mating between individuals of __________ parental generation.
first generation ; genotype
Succeesive; purebreed
State the definition of Mendel’s First Law. ( Law of Segregation)
Characteristics of an organism controlled by a pair of alleles and only one of the allelic pair is inherited by the gametes.
