The more intense the light is, the faster the rate of photosynthesis will occur
I don’t think we would have the same countries. i feel like everything would be connected, like maybe a few really big countries instead of hundreds of different countries. i feel we would look different that how we already look because there would be more of different type of people around each other, resulting in mixed race reproducing.
Answer:
The frequency of pink flowers will increase to near one over time, while the frequency of white flowers will decrease to near zero.
Explanation:
There are two forces acting as selective pressures.
- Slugs prefer to eat pink-flowering over white-flowering plants → selective pressure against the pink genotype → plants with pink flowers suffer from severe herbivory and are more likely to die.
- Bees prefer to pollinate pink over white flowers → selective pressure favoring the pink genotypes → Plants with pink flowers produce more seeds than plants with white flowers.
When the researcher removes all slugs from the study population, he/she eliminates the selective pressure against the pink genotype, leaving only the force acting in favor of the genotypes. So plants with pink flowers will produce more seeds that will originate more plants with pink flowers. As there is no predator over these plants, they will keep reproducing and growing pink flowers. Over time, the frequency of the pink genotype will increase, while the frequency of the white genotype will decrease.
Answer:
The correct answer is peas have characteristics that have two forms.
Gregor Mendel used pea plant <em>Pisum sativum </em>as a model plant for his experiments. There are many applications behind his choice, one of which is observable characteristics with contrasting traits.
Pea plant has many observable characteristics which exist in two forms for example:
- Plant size (tall or dwarf)
- Pea color (green or yellow)
- Pod shape (yellow or green)
- Flower color (purple or white)
- Pea shape (round or wrinkled)
Other benefits were like: short life cycle, it produces a good number of offspring in a cross, easy to breed or cross-pollinate, hybrids were liable, bisexual flowers which makes it easy to produce true-breeding etc.
Answer:
3 yellow : 1 green
Explanation:
Yellow seed allele (Y) is dominant over the green seed allele (y).
A cross between two true breeding parents is done: YY x yy
The F1 offspring would be heterozygous Yy.
<u>If the F1 is selfed (Yy x Yy) the expected ratios for the F2 generation according to Mendel's law of segregation would be:</u>
- 1/4 YY (yellow)
- 2/4 Yy (yellow)
- 1/4 yy (green)
So 3/4 seeds of the F2 would be yellow because they have a dominant Y allele, and 1/4 would be green.
The phenotypic ratio will be 3 yellow : 1 green
