In a plant, a tall variety was crossed with a dwarf variety. All F₁ plants were tall. When F₁xF₁ plants were interbred, 9/16 of the F₂ were tall and 7/16 were dwarf. Explain the inheritance of height by indicating the number of gene pairs involved and by designating which genotypes yield tall and which yield dwarf. (Use dashes where appropriate.)

Hi everyone. Let's look at our next problem. It says the offspring obtained by crossing two different parents is called blank. And the offspring obtained by crossing the first filial generation is called blank. Well let's recall more content video that we crossed two different parents. The offspring that generation is called F. one, meaning the first filial generation filial from Latin meaning son. When we cross the first filial generation with each other, so essentially inbreeding The offspring of that f. one generation that is then called the F. Two generation. So when we look for our answer choices, we see that choice A. Is in the correct um names and correct order F. One and F. Two. So again, offspring obtained by crossing two different parents called F. one. And the offspring obtained by crossing the first filial generation to cross them with each other is called F. To see you in the next video.
