Indicate the percentage of tetrads that would have 0, 1, 2, 3, or 4 viable spores after saccharomyces cerevisae a /α diploids of the following genotypes are sporulated: (a)- a true-breeding wild-type strain (with no mutations in any gene essential for viability). (b)- a strain heterozygous for a null (completely inactivating) mutation in a single essential gene. for the remaining parts of this problem, consider crosses between yeast strains of the form a x b, where a and b are both temperature-sensitive mutations in different essential genes. the cross is conducted under permissive (low-temperature) conditions. indicate the percentage of tetrads that would have 0, 1, 2, 3, or 4 viable spores subsequently measured under restrictive (high-temperature) conditions. (c) a and b are unlinked, and both are 0 m. u. from their respective centromeres. (d)- a and b are unlinked; a is 0 m. u. from its centromere, while b is 10 m. u. from its centromere. (e)- a and bare 0 m. u. apart. (f)- a and b are 10 m. u. apart. assume all crossovers between a and b are scos (single crossovers). (g)- in part (f), if a four-strand dco (double crossover) occurred between a and b, how many of the spores in the resulting tetrad would be viable at high temperature?

Apopulation of rabbits live in a local forest. some had a mutation for a large body and long legs. the graph below shows the number of both the mutant and the normal rabbits over 5 generations. which of the following statements is true for this scenario? question 7 options: the rabbits with the mutation were more successful with restricted food than the normal rabbits. both sets of rabbits were equally successful with the restricted food source.i the normal rabbits were more successful with restricted food than the rabbits with the mutation. the graph does not let us know which rabbit was more successful.
