Biology Quiz:1.3.2Quiz- Basics of Mendelian Genetics (Questions & Answers) Rated 100% Correct!!

How did Mendel make the F1 generation for his experiments? - Answer-He crossed two pure lines. In Mendel's experiment, why did traits show up in the F2 generation that were not present in the F1 generation? - Answer-The traits were recessive. In Mendel's experiment, why did wrinkled seeds show up in the F2 generation, even though they were not present in the F1 generation? - Answer-Wrinkled seeds are recessive. Mendel wanted to find out if the color of the seed of a pea plant affected the seed shape. What experiment did he perform to test this idea? - Answer-He tested seed color and shape at the same time. Mendel wanted to find out if the pattern of inheritance for one trait affected the pattern of inheritance for another. What experiment did he perform to test this idea? - Answer-He performed dihybrid crosses. Mendel wanted to find out if the pattern of inheritance for one trait affected the pattern of inheritance for another. What experiment did he perform to test this idea? - Answer-He tested seed color and shape at the same time. The height of a type of plant is a normal distribution. Some plants are tall and some are short, but most are in between. What is most likely true about this trait? - Answer-Several different genes control height. What discovery in the 1900s supported Mendel's ideas? - Answer-Chromosomes What led to scientists accepting Mendel's ideas? - Answer-Scientists discovered chromosomes and DNA. What was Mendel trying to determine? - Answer-How traits are passed to offspringWhat was the ratio of dominant to recessive phenotypes in the F2 generation of Mendel's experiments? - Answer-3:1 Which best describes the law of independent assortment? - Answer-Alleles of a trait separate independently when gametes form. Which best describes the law of independent assortment? - Answer-The factors for each trait are separated independently when sex cells form. Which best describes the law of independent assortment? - Answer-When sex cells form, alleles of a trait separate independently. Which best describes the result of Mendel's work with pea plants? - Answer-He found the basic ideas about genetics. Which best describes the result of Mendel's work with pea plants? - Answer-He showed how traits are passed between generations. Which describes a Mendelian trait? - Answer-Humans can have dimples or no dimples. Which describes a Mendelian trait? - Answer-Humans either have attached earlobes or detached earlobes. Which describes a Mendelian trait? - Answer-Humans either have straight thumbs or bent thumbs. Why did Mendel use pure lines in his experiment? - Answer-He needed a control group. Why was Mendel's work not accepted at the time? - Answer-His results were surprising.
