Is inbreeding in flowering plants helpful?Why or Why not?
Step by step
Solved in 2 steps
- What are the albino seedlings using for energy? Will they be able to survive? How's it possible for a deleterious gene like that for feeblemindedness or hemophilia remains in a certain population?You own both fighting Pit and a Japanese Peach. Is it proper to interbreed these dogs? Why?What is the magnitude of inbreeding depression if selfed offspring have four times lower fitness than outcrossed offspring? Under these circumstances, would it be advantageous for a plant to continue self-fertilizing? Explain.
- What is a lethal allele? Would you expect most lethal alleles to be recessive (that is, only ll is fatal), or would you expect many of them to be dominant (LL and Ll are both fatal)? Do you think a plant carrying a dominant lethal allele would survive very long? Do you think such a plant could become abundant in the population?What are evolutionary processes that are associated with allopolyploidyIs generation 2 dominant or recessive? and Why? Is generation 3 dominant or recessive? and Why?
- Why is inbreeding not advisable?A plant breeder found a species of flowering plant with very attractive flowers growing wild in a field and she thought it would appeal to her customers. Some of the plants of this species had red flowers, some white flowers, and some pink flowers. While she would like to be able to offer her customers all three colors of flowers, she only has permission from the landowner to dig up one plant to bring back to the nursery as breeding stock. What would be the best thing for her to do? Top of Form Take a white flowering plant since the white allele could be masking the pink allelle. Take a pink flowering plant since it is likely to carry both the red and white alleles. Take a red flowering plant since it could produce all three colors eventually. Take a red flowering plant since the red allele is likely the dominant one.Give at least three reasons why hybrid seeds are expensive.
