Clicker Questio: Dow’s sdroe is a eaple of:
aneuploidy
Law of segregation
if diploid organism with 2 alleles for each trait, during the gametes, gametes will
separate for each other, when they recombine in the next generation,

Document Summary

Clicker questio(cid:374): dow(cid:374)"s s(cid:455)(cid:374)dro(cid:373)e is a(cid:374) e(cid:454)a(cid:373)ple of: aneuploidy: law of segregation if diploid organism with 2 alleles for each trait, during the gametes, gametes will separate for each other, when they recombine in the next generation, Tt male gametes go on top female gametes go on the side. Tt: tt: homozygous dominant tt: homozygous recessive, tt: heterozygous. Yy phentotypic ratio 3:1 (3 yellow, 1 green) Genotypic ratio: 1 yy: 2 yy : 1 yy. Clicker question: the allele for long fingers f is dominant to short (f) fingers. Test cross: dominant phenotype could be tt or tt, recessive phenotype must be tt. If plant with dominant phenotype is tt all the offspring will be tall. Alternatively, if plant with dominant phenotype is tt, half of the offspring will be tall and half will be dwarf. Tt tt tt law of independent assortment: alleles of different genes assort independently of each other during gametes.
