The calculated chi-square value is 3.91, and the critical value is 7.82. The null hypothesis cannot be rejected.
Leaf growth is promoted through increased photosynthesis, but the genetically regulated rate of stomatal production is not altered, leading to a decrease in stomatal density.
Which of the following is closest to the calculated chi-square (χ2) value for the data presented in Table 1? 72.01
What is the recombination frequency between the genes for petal shape and pollen shape?
Phenotype Expected Purple, long 1199 Purple, round 400 Red, long 400 Red, round 133
An allele with more than 39 CAGCAG repeats was inherited by the affected person.
Separation of chromatids occurs once, and there are two rounds of cell division in meiosis.
Meiosis 2 and 3 lead to the formation of cells with 7 chromosomes. During meiosis II, homologous chromosomes separate. During meiosis IIII, sister chromatids separate. Two cells combine during fertilization to produce…
The mean number of medium-red phenotypes per cross is 20.8. The distribution of phenotypes suggests that multiple genes are involved in grain color determination.
