Biology Chapter 9 Quiz

The particular variants of a gene. One parent's allele may code for blue eyes, while the other may code for green eyes

The hereditary information contained in the DNA of chromosomes that is passed on from each parent from a particular characteristic.

Individual with identical alleles

The hereditary information contained in the DNA of chromosomes that is passed on from each parent from a particular characteristic.

The particular variants of a gene. One parent's allele may code for blue eyes, while the other may code for green eyes

Individual with identical alleles

When this allele is present, it is always expressed. (PP or Pp)

Individual with alternate alleles

Individual with identical alleles

Individual with identical alleles

When this allele is present, it is always expressed. (PP or Pp)

Individual with alternate alleles

When this allele is present, it is always expressed. (PP or Pp)

Both copies of this allele must be present to be expressed( pp lower case represents the recessive allele)

Individuals who inherit homozygous alleles.

When this allele is present, it is always expressed. (PP or Pp)

Individuals who inherit homozygous alleles.

Both copies of this allele must be present to be expressed( pp lower case represents the recessive allele)

Recessive gene

Method to determine if an individual with a dominant trait is homozygous or heterozygous.

Individuals who inherit homozygous alleles(PP,pp)

The alleles one inherits

The alleles one inherits P from maternal side and P from paternal side.

Method to determine if an individual with a dominant trait is homozygous or heterozygous.

The trait produced by inheritance of alleles for a particular gene

The trait produced by inheritance of alleles for a particular gene

The alleles one inherits P from maternal side and P from paternal side.

Individual who has both alternate alleles for a single trait.

The trait produced by inheritance of alleles for a particular gene(i.e purple flowers. It is what you can see)

Individual who has both alternate alleles for a single trait.

The trait produced by inheritance of alleles for a particular gene

The alleles one inherits P from maternal side and P from paternal side.

An individual who has both alternate alleles for two traits

Individual who has both alternate alleles for a single trait.

Individual who has both alternate alleles for a single trait.

An individual who has both alternate alleles for two traits

An individual who has both alternate alleles for two traits. ( i.e Pp for color and Rr for round)

A square box

It is used to diagram the probability of offspring inheriting a particular allele.

Handing down (1) alele

It states that a sperm or egg caries only one allele for each inherited character because chromosomes carrying allele pairs segregate during gamete formation

The law that deals with the inheritance of a single character( eye color).

Sex cells only contain (1) allele

Each pair of chromosomes carrying alleles segregate independently or other pairs of chromosomes carrying alleles during gamete formation.

Genes located on different chromosome are inherited independently of one another
