The binucleate crook cell would develop into the ascus and is called Ascus mother cells. The two nuclei in the ascus mother cell fuse to form one diploid nucleus. The cell that contains the diploid nucleus elongate. The diploid nucleus under goes meiosis ( reduction division) to give rise to four haploid nuclei. The four nuclei divide by mitosis to give rise to eight nuclei and these nuclei forms the nuclei of the eight ascospores which are contained in the ascus.

B) Traits are inherited in discrete units‚ and are not the results of "blending." C) Recessive genes occur more frequently in the F1 generation than do dominant ones. D) Genes are composed of DNA. E) An organism that is homozygous for many recessive traits is at a disadvantage. 2) How many unique gametes could be produced through

Unit 2 Lecture Study Guide 1) What are the parts of an atom? Where are the subatomic particles found? a. The parts of an atom consist of protons‚ electrons‚ and neutrons. b. The subatomic particles are found in either the electron cloud‚ or the nucleus. The electrons are found in the electron cloud‚ which circles the atom‚ and the protons and neutrons are found in the tiny nucleus of the atom. 2) How does the Atomic Mass # differ from the Atomic #?

1-A cross gives a 3:1 phenotypic ratio. What are the genotypes of the parents? 3:1. (heterozygous parents) 2- According to Mendel’s law of segregation‚ parents who both have the genotype Aa would produce what gametes? A germ cell Aa undergoes meiosis 3-What is the genotype of a plant that produces green peas? Yellow peas are dominant. Yy or yy when crossed with a heterozygote (Yy) will give some offspring that are green 4- To determine whether an animal with the dominant phenotype is heterozygous
