Meiosis & Mendelian Genetics

A _______ is an alternative form a gene.

• chromosome

• sister chromatid

• allele

• telomere

a trait that is always expressed if present is _____________________

• Recessive

• Dominant

• Strong

• True

a trait that is masked unless 2 copies are present is ________________________

• recessive

• dominant

• weak

• hidden

alleles for a trait that are the same

• Homozygous

• Heterozygous

• Quasizygous

• Juxtazygous

alleles for a trait that are the different

• Homozygous

• Heterozygous

• Quasizygous

• Juxtazygous

the organism's genetic makeup

• phenotype

• genotype

the physical/observable characteristic

• phenotype

• genotype

Select all that would be considered phenotypes:

• Blonde

• Rr

• Short

• rr

Select all that would be considered genotypes:

• Blonde

• Rr

• Short

• rr

Law of segregation states:

• the two alleles for each trait separate during meiosis

• the two alleles for each trait separate during mitosis

• a random distribution of alleles occur during gamete formation

• a ordered distribution of alleles occur during gamete formation
