Why any human trait is exclusively the result of the genes or of the environment and its example. Introduction: DNA is a genetic material consisting of a long stretch of nucleotide sequences with a 2-m length. It carries genetic information from one generation to the next. A complete list of the DNA sequences is known as a genome, which includes coding and non-coding regions of DNA. Gene is defined as a segment of DNA that codes for mRNA and protein. Homologous chromosomes carry two forms of a gene in the same locus known as alleles. Two alleles of the gene determine the human phenotypic trait with the influence of the environmental factors. The total human genome consists of about 3.1 billion base pairs with 20,000 protein-coding genes.

The shape of radishes may be long (SL/SL), oval (SL/SS), or round (SS/SS), and the color of radishes may be red (CR/CR), purple (CR/CW) or white (CW/CW). If a long, red radish plant is crossed with a round, white plant, what will be the appearance of the F1 and F2 generations?

None

Question #3: In the KeyGene paper, the authors state that it would be useful if pollen from an apomict would transmit apomixis-inducing genes to the female in the cross (assuming the pollen is viable). Assuming there was just one gene conferring gametophytic obligate apomixis, and that the two parents are inbreds, what would be the consequences of such a cross if: a) The apomixis was a dominant trait? Indicate the genotypes and phenotypes (apomict or non- apomict) of the parents, F1 and F2 generations. Remember to include the expected genotypic and phenotypic ratios (or percentages) in the F1 and F2 generations, and to position the female first (left side) in the parental cross. b) The apomixis was a recessive trait? Indicate the genotypes and phenotypes (apomict or non- apomict) of the parents, F1 and F2 generations. Remember to include the expected genotypic and phenotypic ratios (or percentages) in the F1 and F2 generations, and to position the female first (left side) in the…
