Genetic Crosses Flashcards
Haploid
one set of chromosomes
Diploid
two sets of chromosomes
Alleles
different forms of the same gene
Locus
genes position on chromosome
Dominant
An allele that prevents the working of the recessive allele
Recessive
an allele prevented from working by dominant allele
Genotype
genetic makeup of an organism
Phenotype
physical makeup of an organism
Homozygous
alleles are the same
Heterozygous
Alleles are different
Incomplete Dominance
Neither allele is dominant or recessive with respect to each other
Mendel’s Law of Segregation
Inherited characteristics are controlled by pairs of factors (alleles) these separate at gamete formation with only one member of the pair entering a gamete
Mendel’s Law of Independent Assortment
At gamete formation either of a pair of factors (alleles) is equally likely to combine with another pair
Linkage
genes are located on the same chromosome
Sex Linkage
A characteristic is controlled by a gene on the X chromosome
