Answer:
A. Mendel observed green and yellow pea pods in a 3:1 ratio because the F1 generation was heterozygous.
Explanation:
The two true breeding plants in the parental population were homozygous (that is what true breeding means). Therefore, their cross would lead to all heterozygous offspring (see attached punnet square). Green is the dominant characteristic, so all F1 plants had a green phenotype, but Gg genotype.
The F1 cross would therefore be Gg x Gg. See attached punnet square.
The genotypes in the F2 generation are 1 GG: 2 Gg: 1 gg 1
Therefore, the phenotypic ratio is 3 green pea pods (Gg or GG): 1 yellow (gg)
Answer:
DNA.
Explanation:
Type II restriction endonucleases always cleave at or near their recognition sites. They produce small, well-defined fragments of DNA that help to characterize genes and genomes and that produce recombinant DNAs.
The answer is sexual reproduction in which the creation of offspring by fertilization consisting 2 haploid gametes come together to form a diploid zygote with a new genetic combination. The main difference between sexual and asexual reproduction is that asexual reproduction results in a genetically identical offspring whereas sexual reproduction results in a unique offspring in which offspring with a new genetic combination.
I think you should put a check mark by 2, 3,
5, and maybe 6.
Hope this helps.
