a.
To draw: An ascus by the crossing of a mutant allele lys-5 with a wild-type allele lys-5+.
Introduction: The ascospores in the eukaryotes can be present in two types that is the ordered type and the unordered type. In yeast, the ascus consists of spores that are present in unordered types.
b.
To draw: An ascus by the crossing of two mutant alleles lys-5.
Introduction: The genotype is the genetic constitution of the organism while the
c.
To draw: An ascus by the crossing of two wild-type alleles lys-5+.
Introduction: The genotype of an organism is dependent on its genome and also on the environment of the organism. In some of the animals, it is not as typical as the genotype of the mother plays a crucial role. This type of effect is known as a maternal effect. The genes that participate in this are called maternal effect genes.
