Final Study Guide for VT6: Basic Science

A copy of a gene

All chromosomes that are not an X or Y

The dominance of an allele over a recessive Allele. Dominance of traits

Genetic makeup of the offspring (actual allele types present)

(of a cell or nucleus) having a single set of unpaired chromosomes

Chromosomes carry different alleles of a gene

Each chromosome carries identical alleles of a gene

When the offspring genes are superior to that of the parents

The position (location) of a gene on the DNA of the chromosome

Physical appearance of the individual

A tool that helps to show all possible allelic combinations of gametes in a cross of parents with known genotypes in order to predict the probability of their offspring possessing certain sets of alleles

A gene that is expressed only when it is present in two copies or if the other copy is missing

When 2 alleles are both expressed in the offspring. (red fish + blue fish= a red/blue fish, both colors showed on the offspring)

A blending of both parents into the offspring (purple flower + white flower = lavender flower. Like mixing paint)

Occurs if the homozygous condition for an allele cannot exist. (means dead)
