F2 generation has three distinct phenotypes
WebAnswer: It depends on the genotype of the F1 generation (or parents) and on the method of reproduction. If it is a type of reproduction that involves two haploid cells joining (one from each parent) to form a zygote (like in human) then inherritence works like this: If the parents are homozygous... http://thebiologyprimer.com/mendel

WebWe applied this method to rat sperm over three generations (F0, F1 and F2) with multigenerational uranium exposure. Our results show a significant content of uranium in generation F0, and a reduction in the pregnancy rate only in generation F1. ... initial observations yielded different profiles for each generation without any detectable effect ... WebFrom his original experiment, he predicted that in each of the physical characteristics one phenotype would dominate in the F1 generation, masking the recessive phenotype. From his seed shape experiment, he …
WebScience Biology Two alleles at one locus produce three distinctphenotypes. Two alleles of two genes lead tofive distinct phenotypes. Two alleles of six geneslead to 13 distinct phenotypes. (These statementsassume that the alleles at any one locus arecodominant or incompletely dominant andthat each gene makes an equal contributionto the phenotype.)a. WebF1 generation: The F1 dihybrid seeds are yellow and round, with a genotype of YyRr. The F1 plants can produce four different types of gametes: YR, Yr, yR, and yr. We can predict the genotypes of the F2 …
Webratio using the Chi Squared Test. The 9:3:3:1 ratio simply means that nine are wild-type meaning they are normal; six exhibit one mutant and one normal character, three are normal for one trait the other three are normal for the opposite trait; one has both mutant phenotypes. Two different crosses were performed one between vestigial and sepia ... Webwhite plants are crossed, the resulting offspring (i.e. the F1 generation) are all pink. When the pink offspring are crossed to create a third generation (i.e. the F2 generation), 25% of the offspring are red, 50% are pink, and 25% are white. These results are summarized in the next page. 2. handout exploring snapdragons Answer:
