5- Which of the following examples suggested to Charles Darwin that hybridization between different animal species was often of no benefit to the hybrid animals? crossing of a female European wildcat with a male housecat to produce fertile hybrids crossing of a female gray wolf with a male coyote to produce fertile hybrids crossing of a male donkey with a female horse to produce sterile hybrids crossing of a male dog with a female gray wolf to produce fertile hybrids crossing of a female housecat with a male African wildcat to produce fertile hybrids

.what is the purpose of homogenization? it increases the absorption of DNA molecules it decreases the amount of DNA that can be spooled onto a straw  it releases the DNA from the nuclei by breaking apart the cell walls, plasma membrane, and nuclear envelopes. it removes attached proteins from DNA  it removes attached carbohydrates from DNA - . which of the following is an example of quantitive data? the freshman class of the students contained 643 students, 372 males, and 271 females. the absorption peak of cobalt chloride was 510nm  bromelain has optimal enzyme activity at a pH of 7  the color of cobalt chloride was pink the mass of the onion was 50 grams

Which of the following examples suggested to Charles Darwin that hybridization between different animal species was often of no reproductive benefit to the hybrid animals? crossing of a female European wildcat with a male housecat to produce fertile hybrids crossing of a male dog with a female gray wolf to produce fertile hybrids crossing of a female housecat with a male African wildcat to produce fertile hybrids crossing of a male donkey with a female horse to produce sterile hybrids crossing of a female gray wolf with a male coyote to produce fertile hybrids

7. Red blood cells can possess a surface antigen called the Rhesus (Rh) factor. Rh+ (presence of the factor) is dominant over Rh¯ (absence). A village of population 400 was sampled and the frequency of the allele coding for Rht was found to be 0.356. a) Determine the number of individuals in the village who will be Rh b) Determine the probability of being heterozygous

The "green revolution": food producers needed to maximize yields in the first half of the 20th century. From the 1950's to 1960’s, there was an extensive effort world-wide to increase crop productivity. Norman Borlaug, the "Father of the Green Revolution", is credited with saving over a billion people from starvation. He received the Nobel Peace Prize in 1970. The approach applied genetic crosses to develop high yield varieties of cereal grains, as well as efforts to improve irrigation infrastructure, management techniques, hybrid seed distribution, synthetic fertilizers, and pesticides. Let's consider additive alleles and their contribution to a trait: Problem: Additive allele 'A' contributes to increased yield of rice. Nonadditive allele 'a' does not. Hence, there are three genotypes and phenotypes possible: -> AA: high yield → Aa: intermediate yield aa: low yield Imagine that rice crop yield is controlled by four additive genes, A, B, C, and D. 1. Farmer Leslie has a true-breeding…
