Ayeast strain with a mutant spo11— allele (the mutant allele is nonfunctional; it makes no spoil protein) has been isolated. what do you suppose is the phenotype of this mutant strain?

The protein Spo11 performs an essential function in starting the process of recombination. If yeast exhibits a mutation on spo11- allele, it turns non-functional and it cannot generate the protein spo11 anymore. As a consequence, it cannot go through any recombination process, and the spores generated from it would be inviable because of aneuploidy. Aneuploidy refers to a condition in which the cell comprises an unusual number of chromosomes.

children tend to take more after their grandparents more than their parents. it’s the dna you received that was passed down to you somewhere in your family. maybe one of your grandparents had/has straight hair and you might have gotten it from them.
