Mendel's First and Second Laws

What is another name for Mendel's 1st Law?

• law of cross breeding

• law of segregation

• law of test cross

According to the Law of Segregation, each characteristic is controlled by

• 3 alleles

• 4 alleles

• 2 alleles

Only one characteristic is observed.

• monohybrid cross

• dihybrid cross

• test cross

steps in Mendel's experiment in order

• produce F2 generation, produce P generation, produce F1 generation

• produce P generation, produce F1 generation, produce F2 generation

• produce F1 generation, produce F2 generation, produce P generation

when true breed self fertilized, they produce offspring that has

• the same phenotype as the parent

• different phenotype as the parent

• no phenotype from the parent

monohybrid cross involves

• crossing between 2 individuals with the same phenotypes

• crossing between 2 indoviduals with no phenotype

• crossing between 2 individuals with different phenotypes

PP x pp will produce

• pp

• Pp

• PP

when F1 self cross (Pp x Pp) the F2 genotype ratio is

• 1 PP : 1 Pp : 2 pp

• 3 PP : 1 Pp

• 1 PP : 2 Pp : 1 pp

in test cross, the perdiction if all offspring show dominant phenotype, genotype of unknown parent is

• heterozygous

• homozygous dominant

• homozygous recessive

if half offspring show dominant phenotype & another half show recessive phenotype, predict the genotype of parent

• heterozygous

• homozygous dominant

• homozygous recessive
