BONUS: The native residents of Basque country in the western part of the Pyrenees Mountains between France and Spain still speak remnants of Euskera, a language the first European settlers brought in more than 10,000 years ago. The Basques have unusual frequencies of cetain ABO and Rh blood types, rare mitrochondrial DNA sequences and cell surface antigen patterns and a high incidence of a mild form of muscular dystrophy. So is this an example of ___________________.

The genes in a population comprise its  

Which is an example of an open-ended question? 

  A trait that occurs more frequently in both members of identical twins than in both members of fraternal twins probably has a significant____________ component.

SNPs are sites of variability in genomes.

For the ABO gene, the three alleles are the IA, IB and i alleles. The i allele (for the the “O” blood type allele) is recessive to both the IA and IB alleles (the “A” and “B” alleles).The alleles IA and IB show _______________.

For X-linked traits, the frequency of the recessive phenotype in males and females is

The most informative studies on how and to what degree heredity and the environment influence human traits have relied on data from

Dwarfism in humans is a dominant trait. Therefore, an individual who is dwarf will be homozygous.

When a person dies due to an allele combination than it is called as lethal allele combination.
