Hi,
Attached is solution diagram. You can see that true breeding means both have same alleles for purple PP and white WW flowers.
They were crossed to produce hybrid plants that all had purple flowers PW because purple was the dominant trait.
However, upon self fertilization of those hybrid plants, both purple and white flower plants were produced in 3:1.
Hope it helps!
Answer:
Genetic drift is a mechanism of evolution in which allele frequencies of a population change over generations due to chance (sampling error).
Genetic drift occurs in all populations of non-infinite size, but its effects are strongest in small populations.
Genetic drift may result in the loss of some alleles (including beneficial ones) and the fixation.
Genetic drift can have major effects when a population is sharply reduced in size by a natural disaster (bottleneck effect) or when a small group splits off from the main population to found a colony (founder effect).
The sporophyte generation of a moss dependent on the gametophyte generation is that it is used for support and most of its nutrients.A sporophyte is the diploid multicellular stage in the life cycle of a plant or alga and it<span> develops from the zygote produced.</span>
The first statement matces with the last option - autosome
The second one goes with chromosome theory
Then, third is diploid
The next - haploid
Sixth - <span>linkage
Then </span>x chromosome and y <span>chromosome
Hope you still need the answer because this one is really helpful.
