Question

Using the information provided in Problems 10 and 11, determine the genotype and phenotype of parents that produce the following progeny:

3/4 brown : 1/4 yellow

Accepted Answer

Hi, everybody. Let's look at our next question. It says which of the following type of allele combinations was produced when Mendell conducted the hybridization experiment by crossing one pure tall, big T, little T and one pure dwarf, little T little T P plant. Well, when you cross homocide is dominant and recessive, there's only one type of combination that can be produced because the dominant parent can only produce big T alleles. While the recessive parent can only produce little T alleles. So therefore, 100% of the offspring will be big T little T heterocyclic. It's so let's look at the answer choices and we see that choice C is big T, little T, it can be a little confusing because we often, since generation, we would call this generation F one, the offspring that are produced out of that cross. Um Since F one is always going to give you just 100% Harris, I get all the same in this situation. We don't often look at the F one generation. Um We're usually looking at the F two generation where you cross do the hybrid crosses with hetero sickos, crossed with hetero sickness Um And then you do see a combination of homesickness, dominant homesickness, recessive and heterocyclic it all of the above. Um So you might be tempted to choose choice D all of the above because you're thinking of the more commonly contemplated F two generation. But this question specifically asked us what is produced when he hybridized the pure tall and the pure dwarf pea plant. So we're talking about that F one generation. So that's why choice. A big t, little T choice B, I'm sorry to say big T, big T choice be little T little T and choice D. All the above are not our answer choices. So again, which of the following type of allele combinations produced when Mendel conducted the hybridization experiment, crossing one pure tall and one pure dwarf pea plant is choice C big T little T, see you in the next video.
