2022 Genetics Final Exam: BIOL 301(BIO 3303) Final Exam Mendel performed many types of crosses, including those in which the same genotypes are crossed but the sexes of the parents are switched. These are known as What is the process of synthesizing single-stranded RNA from template DNA? What is the process of synthesizing proteins from mRNA sequences In peas, the round allele is dominant over the wrinkled allele. if a plant with round peas is crossed to a plant with wrinkled peas...

Lecture 6: Vocab: ● Autosome: ○ Any chromosome not considered as a sex chromosome, or is not involved in sex determination. ○ It occurs in pairs in somatic cells and singly in sex cells (gametes) ● Bivalent: ○ a pair of homologous chromosomes. ● Drosophila melanogaster: ○ a species of fruit Fly much used in genetics because of the large size of its chromosomes. ● Epistasis (gene x gene interaction): ○ refers to genetic interactions in which one gene modifies the eff...
