Answer:
See the answer below
Explanation:
1. <u>Only one phenotype</u> is present in the F1 generation offspring. Since tallness was dominant over shortness, all the offspring in the F1 generation appeared tall.
2. <u>Two phenotypes </u>are present in the F2 generation - 9 tall and 3 short. The short trait reappeared at the F2 generation.
3. The genotype of the F1 offspring would be heterozygous. Assuming the purebred tall is AA and the purebred short is aa:
AA x aa
Aa Aa Aa Aa
All the F1 offspring will appear tall and their genotypes would be heterozygous.
4. Assuming that the allele for height is denoted with A (a), <u>the genotype of the purebred tall plant would be AA. </u>
5. In a similia vein, <u>the genotype of the purebred short plant would be aa. </u>
Answer:
A woman is born with all of her eggs, which are stored in her ovaries. The ovaries also make the hormones estrogen and progesterone, which control her period (menstruation) and the release of eggs (ovulation). Menopause happens when the ovaries no longer release an egg every month and menstruation stops.
Chesapeake bay is an area that has suffered from overharvesting and eutrophication. Eutrophication is an enrichment of water by nutrients salts that causes structural changes in the ecosystem such as increased formation of algae and aquatic plants, depletion of fish species among other effects. The greatest source of nitrogen and phosphorus in a Chesapeake bay is agriculture
Answer:
Your answer is D). Like most cold-blooded animals, geckos' bodies are unable to maintain a homeostatic body temperature on their own, therefore they must bask in the sun in order to increase their body heat, and hide in the shade when it's too hot.
