The number of F2 plant of each of the four phenotypes that we expect is as follows 450 blue oval: 1 white round:50 blue round :1 white oval. According to the father of genetic that is Mendel F2 generation is obtained after crossing F1 generation
That is because as energy is transferred at least 10% of that energy gets transferred to the next source. That is why.
It took me a bit too figure out and understand but yea, i did it last year now i get it!
Answer:
If mother 1 is a carrier of hemophilia, it is likely that her son would in fact have hemophilia while the son of mother 2 does not. Mother 1 would have the genotype XᴴXʰ, meaning she has one recessive allele for hemophilia, while the father would have the genotype XᴴY, and would neither be afflicted with hemophilia nor carry it. If you do a punnett square, it shows that the son of mother 1 would have a 50% chance of having hemophilia, since he wouldn't have a second X chromosome with a dominant allele to mask the recessive hemophilia allele. Also, if mother 2 has the homozygous dominant genotype XᴴXᴴ despite the father having hemophilia and the genotype XʰY, a punnett square for this couple proves that their son would have a 0% chance of having hemophilia. Therefore, it is very likely that their sons were not switched at birth and the correct answer is D: The fact that the father in couple 2 has hemophilia would not predispose his son to hemophilia. The first couple has no valid claim. Hope this helped!
