5) Mendel's law of independent variety states that
A) chromosomes sort independently of each and every other during mitosis and meiosis. B) genes type independently of every other in animals although not in crops. C) impartial sorting of genes makes polyploid plants under a few circumstances. D) each set of alleles segregates independently of some other pairs of alleles during gamete development. E) genes are fixed concurrently during gamete development.
6) A testcross is
A) a mating among an individual of unknown genotype and someone homozygous recessive for the trait interesting.
B) a mating between a person of unidentified genotype and an individual heterozygous for the trait appealing. C) a mating between an individual of unknown genotype and an individual homozygous major for the trait appealing.
D) a mating between two individuals heterozygous for the trait appealing. E) a mating among two people of unknown genotype.
