- In 1-3 sentences each define the follwing terms: complex trait, concordance, environmental variance.Leg length is polymorphic within a population of lizards, with much of the variation controlled by (segregating for alleles A/B). Homozygous BB lizards have short legs and move slowly, and so are easy prey to hawks. As a result, only 20% of them survive to reproduce. Homozygous AA individuals are fast but struggle to hold onto branches during hurricanes, and so only 50% of them survive to reproduce. AB heterozygotes are both relatively fast and can grip branches well. 80% of them survive to reproduce. The frequency (q) of the B allele at birth is 10%. Calculatehe absolute mean fitness of the population using the mean fitness formula. Answer fast for ?A graduate student is studying a population of bluebonnets along aroadside. The plants in this population are genetically variable. Shecounts the seeds produced by each of 100 plants and measures the meanand variance of seed number. The variance is 20. Selecting one plant,the student takes cuttings from it and cultivates them in a greenhouse,eventually producing many genetically identical clones of the sameplant. She then transplants these clones into the roadside population,allows them to grow for one year, and then counts the seeds produced byeach of the cloned plants. The student finds that the variance in seednumber among these cloned plants is 5. From the phenotypic variancesof the genetically variable and the genetically identical plants, shecalculates the broad-sense heritability.

- In sweet pea plant, an allele for purple flowers (P) is dominant when paired with a recessive allele for red flowers (p). An allele for long pollen grains (L) is dominant when paired with a recessive allele for round pollen grain (l). Bateson and Punnett crossed a plant having purple flowers/long pollen grains with one having white/flowers/round pollen grains. All F1 offspring had purple flowers and long pollen grains. Among the F2 generation, the researchers observed the following phenotypes: 296 purple flowers/long pollen grains 19 purple flowers/round pollen grains 27 red flowers/long pollen grains 85 red flowers/round pollen grains What is the best explanation for these results?The observable traits expressed by an organism are described as its _______. a. phenotype b. genotype c. alleles d. zygoteA bean breeder is working with a population in which themean number of pods per plant is 50 and the variance is10 pods2.
