FLASHCARD DATA FOR BASIC PRINCIPLES OF GENETICS Topic 1: Mendel’s Genetics | 1. |Offspring that are the result of mating between two genetically different kinds of parents--the opposite of purebred. |hybrid | | 2. |The study of gene structure and action and the patterns of inheritance of traits from parent to offspring. This is the branch |genetics | | |of science that deals with the inheritance of biological characteristics.

used PCR to detect the Alu insertions by amplifying the PV92 region on chromosome 16 in order to detect the presence or absence of Alu at this locus. The result shows that 78% of the population in this population had a genotype “+/-”‚ and rest of the 22% of the populations had a genotype

has two alleles in the flies’ genotype‚ or genetic makeup. In the parent generation (P)‚ the flies used are homozygous‚ meaning they have two of the same alleles (“Mendelian Genetics”). The females are winged‚ and since that is a dominant allele‚ it is represented by a capital letter F. That means the female genotype is FF‚ because they get one allele from each parent. The males are wingless‚ which is a recessive allele represented by a lowercase f. Their genotype is ff. A Punnett square can be

If an individual has a Gg genotype‚ half of his gametes should have the G allele‚ and the other half should have the g allele. F 3. A Punnett square is a chart that allows you to easily determine the expected genotypes in the offspring of two parents. (expected percents) T 4. In a cross between two homozygous dominant individuals‚ 25% of the offspring may have the recessive

Principles of Biology I Exam 4 Review Questions 1. What is the difference between a genotype and a phenotype? 2. Write the genotype of a homozygous recessive‚ homozygous dominant‚ and heterozygous pea plant using the trait flower color (p). 3. Different versions of a gene are called ____________. 4. Why are there always two alleles present for each gene at a specific locus? 5. True or False. A dominant allele is always written with a capital letter‚ whereas the recessive allele

plastic cup while the genotype was BB. The legs’ phenotypes were pearly white pipe cleaners and the genotype was ff. The crustacean had deep blue pom poms for eyes and the genotype was Ii. For antennae‚ the crustacean had soft qtips and the genotypes were Kk. One of Joy’s structural adaptations were vibrant purple stripes to help the crab camouflage in the colorful rainforest. She also had sharp teeth to scare off predators. Her husband was a heterozygous plastic cup whose genotype was Bb. His legs were

evolution of the species. Charles Darwin’s theory of evolution emphasizes that populations‚ not individuals‚ evolve. The purpose of my experiment was to test the allele and genotype frequencies. Alleles for a gene are represented by letters of the alphabet. The theory of Hardy-Weinberg states that an allele and genotype frequencies in a population will remain constant from generation to generation in the absence of other evolution.

Southwest CTA. The research was organized to find the allele and genotype frequency of people who use their right hand versus their left hand. The data showed that the dominant allele was more frequent than the recessive‚ and the genotype frequencies amongst the three were not equal. After studying the chi-squared tests‚ we have decided to reject the null hypothesis because there was a significant difference across the three genotypes. __________________________________________________________________________
