Answer:
Because the F1 plants all had a lowercase a/short plant allele, there was a 25% chance that two plants would contribute it to their offspring and they both did sometimes to make a aa offpsring.
Explanation:
All the F1 plants were heterozygous, so when they were crossed, the resulting genotypic ratio was 1 AA : 2 Aa : 1 aa. As you can see, this is the first time since the parent generation that there is a aa genotype and short plant phenotype, so that's why short plants reappeared.

Answer:
An angiosperm is a plant that produces flowers. The angiosperms, also identified as the flowering plants, belong to one of the vital groups of plants having seeds.
Explanation:
The researchers prepare an intron-free copy of the eukaryotic gene for the use in creating the transgenic bacteria by using the reverse transcriptase to make the cDNA from the mature mRNA
The structure of the eukaryotic genes. Most of the eukaryotic genes are contain the segments of the coding sequences (exons) that interrupted by the noncoding sequences (introns). Both the exons and the introns are transcribed to yield a long and primary RNA transcript.
Eukaryotic DNA is the linear, compacted into the chromosomes by the histones, and has the telomeres at each end to protect from the deterioration. The Prokaryotes contain the circular DNA in addition to the smaller, transferable DNA plasmids. Eukaryotic cells contain the mitochondrial DNA in the addition to the nuclear DNA

Answer:
The answer is "species richness."
Explanation:
It is a term that relates to the amount of species in a environment, and also has to do with measuring the diversity of a species in a community.
