1. In cats the development of ear length is sex linkedwith the dominant allele causing a long ear to develop. Therecessive allele causes a short ear to develop. If a male catwith long ears is crossed with a female cat that is heterozygous for ear alleles, then what would be […]

Describe the journey of a hypothetical enveloped (-) RNA virus through three basic host barriers to infection: Physical b arriers, Innate immune response and adaptive immune response. After overcoming physical barriers, how are viruses recognized at each step, what cells are involved, what soluble factors are involved, which adaptive immune […]

1. In each of the following types of growth, how is the rate of growth (dN/dt) influenced by the population size (N)?Linear:Exponential:Logistic: 2. Note the following data concerning two species of paramecia. The abiotic factors (growth medium, temperature, etc) are identical in all flasks. Is there evidence of competition between […]

A cross in corn is carried out with three linked genes in a triply heterozygous genotype for the alleles pairs (A, a), (D, d), and (R, r). The dominant allele A results in red leaves; aa plants have green leaves. The dominant allele D results in tall plants; dd plants […]
