24 Cards in this Set

  • Front
  • Back
the discredited idea that genes of the parent are averaged in the offspring, like the mixing of paint
blending inheritance
Mendel's idea that genes retain their distinct identies as they are passed from one generation to the next.
particulate inheritance
two identical allels present in a genotype
homozygous
the X and Y chromosomes, whose arrangement govern sex development
sex chromosomes
an allele that is expressed only when it is homozygous
recessive
two genes that lie close together on the same chromsome, and are usually inherited as a package deal, like white face and blindness in Australian sheep dogs
linked genes
the X chromosome in a male has no homologue; alleles on the X have no counterpart on the Y, So the terms homozygous and heterozygous have no meaning in this situation. What is the term for alleles that have no homologous partner
hemizygous ???
a population that breeds true for a trait must contain all individuals that have which sort of genotype.
homozygous
Alleles like A,B, and O blood group alleles, which exist in more than two forms in various individuals of a population
multiple alleles
the appearance of a trait
phenotype
the combination of alleles present in an individual
genotype
the heterozygous individuals have a phenotype that is intermediate between the phenotypes of the two different homozygotes
incomplete dominance
an allele that is expressed equally whether it is homozygous or heterozygous
dominant
what is the name for an individual in which different groups of cells in the body are genetically , like two eyes of different colors
mosaic
two different alleles present in a genotype
heterozygous
a segment of DNA that encodes one protein
gene
this part of the flower where the pollen attaches to fertilize the ova
pistil
different forms of a gene
alleles
the part of a flower that makes the pollen
anther
two sets of chromosomes (two copies of every gene)
diploid
one set of chromosome ( one copy of every gene)
haploid
rules of inheritance
genetics
one gene can cause several phenotic traits

lactose sugar
pleiotropy
everybody in my family for four generations has blue eyes. What is this term?
true breeding
