However, if you need the extra support, a different app may be more appropriate. If you know what types of food meet your calorie goals, this deficiency may not be problematic. It will only draw nutrition data from the original recipe webpage or information you enter manually. With browser integrations and a somewhat complicated online user guide, getting started with this app may be a challenge for some.Īdditionally, Paprika doesn’t always include nutrition information. One drawback to this app is the user interface may not be as easy to navigate as some of the other meal planning apps on this list. It can also detect timer directions within a recipe so that you can set cooking timers directly from the app. The app will keep your screen turned on while you’re working from a recipe. Additionally, Paprika detects when more than one recipe needs the same ingredient and consolidates the relevant grocery lists for you.

Additionally, you cannot add your own recipes, set calorie preferences, view nutrition information, or save previously used meal plans unless you upgrade to the pro version. Some recipes aren’t available in the free version of the app. Additionally, you can use the meal prepping feature to prep meals ahead of time by adjusting the number of portions in the recipe. The app also features the option to use the ingredients you have on hand by filtering recipes based on ingredients you enter into the app. An additional bonus is that the recipes all take under 40 minutes to prepare. The app builds your meal plan by taking your diet preferences and food allergies into account during set-up making it easier to follow if you have dietary restrictions.Īfter you’ve entered your preferences, you’re presented with a variety of recipe choices, complete with full-color photos, simple instructions, and an organized grocery list.

I'm using a conda environment with Python version 3.9.7, The dosage may augment the effects of hybridity on gene expression and phenotypes. The effects of genome merger (hybridity) and doubling on growth vigor are testable in diploid hybrids (merger only) and allotetraploids (merger and doubling, “super” hybrids). The allotetraploids are genetically stable and tractable, which provides an excellent model system for mechanistic studies on polyploidy and hybrid vigor. We developed the Arabidopsis allotetraploids to study molecular mechanisms of hybrid vigor. A molecular model of heterosis suggests that expression alteration of regulatory genes modulate expression of housekeeping genes and output traits in hybrids and allopolyploids, leading to growth vigor. The inability to discern a molecular basis for hybrid vigor is partly because F1 hybrids segregate, making it difficult for molecular tests. ![]() The “dominance” model suggests complementation of slightly deleterious recessive alleles in the hybrids, whereas the “overdominance” model indicates that the genes have greater expression when they are heterozygous. Two models have been fascinatingly debated over a century. Although hybrid vigor has been commonly observed and widely utilized in plant and animal production, the mechanisms remain elusive. Hybrid vigor was also observed in embryo development and reproductive traits in mammals. Since the introduction of hybrids in 1920’s, the yield of maize has steadily increased sixfold. ![]() In 1910’s, heterosis was rediscovered in maize by George H. Heterosis is a widespread phenomenon that has intrigued many scientists including Charles Darwin (1876) who systematically characterized growth vigor in cross-pollinated and self-pollinated plants of many species. For example, hybrid plants like maize and polyploid plants like wheat grow larger and more vigorously than their parents. In general, heterosis refers to increase in stature, biomass, and fertility of a hybrid that is superior to one or both parents. ![]() Heterosis or commonly known as hybrid vigor is evolutionarily defined as that the heterozygotes have higher fitness in a population than the homozygotes. |
