What would be the consequence of the resulting gametes if each of the following occurred? (discuss the consequence for all four gametes produced).
a. nondisjunction (lack of separation) of one homologous pair in meiosis i
b. crossing over does not complete – the breakage of the two sister chromatids occurs, but they are not joined to the opposite chromosome.
c. synapse does not occur between the sex chromosomes, so each replicated sex chromosome lines up individually in meiosis i.

Yeast cells reproduce quickly by budding. this is a form of reproduction so all the yeast cells a) sexual; vary b) asexual; vary c) asexual; are identical d) sexual; differ from the parents submit hint structures and functions of cells cellular reproduction

If a cell is placed into a hypertonic environment, what will happen to it ? a)it will shrink or shrivel b)nothing c)it will burst d) it will expand or enlarge

Suppose a particular species of tulip plant has three alleles for the gene that codes for flower color. the cr allele produces red tulips, the cp allele produces purple tulips, and the cw allele produces white tulips. cr is dominant over cp and cw, and cp is dominant over cw. for each of the following crosses, determine the expected ratio of offspring for each flower color. cr cp x cp cw cr cw x cp cw 1 red: 1 purple : 0 white, 1 red: 2 purple: 1 white, 2 red: 1 purple 1 white, 1 red: 3 purple : 0 white, 2 red: 0 purple : 2 white, 2 red: 2 purple : 0 white
