Document Summary
Testcross is the breeding of an organism of __________________ with a. Testcross for seed texture genotype: unknown could be homozygous smooth or heterozygous smooth. The parental crosses that mendel did in his earlier experiments involved parental varieties that differed in a single trait (i. e. , ____________________crosses) By using plants that were ____________________________________ for two different traits, mendel tested if ________________________________. He hypothesized that the __________________ __________________ __________________ (null hypothesis), or they would be independently inherited (alternative hypothesis). If genes sort out together then the f2 will show a 3:1 phenotype. Combinations from sy and sy gametes if genes segregated together : But, if they sort out independently then the f2 will have a 9:3:3:1 phenotypic ratio. Results showed a 9:3:3:1 ratio the null hypothesis is rejected! But, __________________tend to be inherited together because they are located. --linked genes two different genes that are on the same chromosome. Genes on the same chromosome _____________ stay together.
