Answer:
Let's recall Mendel's law of independent assortment that states, "During the formation of gametes, alleles of genes assort independently into each gamete"
How can the random distribution of alleles result in a predictable ratio?
For example, We have a trait for flower color either yellow or white, and the alleles for the flower color are Y and y. The yellow flower color is a dominant trait, and be expressed if plant has YY or Yy genotype. We cross a plant with genotype Yy with another plant Yy.
P1 Yy x Yy
F1 YY : Yy: Yy: yy
Phenotype Yellow: yellow: yellow: white
Genotypic ratio 1 : 2 : 1
Phenotypic ratio 3 : 1
So, we see that phenotypic ratio is different from genotypic ratio. Although the distribution of alleles is random but still there are only four possible outcomes for a trait. Hence, we can predict the phenotypic and genotypic ratio of offspring by drawing a punnet square or gamete formation.
Answer:
The correct answer is option B. medicare select.
Explanation:
A Medicare select policy is a medicare policy that limits the coverage to the network of hospitals, doctors, and healthcare providers. This medicare plan allows the insured to negotiate with the healthcare providers so it is cost-effective as they charge less for their services.
Other plans given in options such as advantage medicare give a wide range of network of healthcare provider however they charge more than the medicare select plan.
Thus, the correct answer is option B. medicare select.
No.... the weight of a substance is the mass of the substance multiplied with the acceleration due to gravity on it.
Answer:
A. DNA--->mRNA--->tRNA--->protein
Explanation:
This is the central dogma of life where it goes from DNA to mRNA via transcription. From mRNA to a protein via translation. tRNA is part of translation which helps to make the protein.
Answer:
The correct answer will be option-seed texture.
Explanation:
Gregor Mendel is known for his experiments on the pea plants by studying the traits of the plants. He observed the seven characters of the pea plants in his experiments:
1. Colour of seed albumen- which is yellow or green
2. The texture of ripe seed- which are smooth or wrinkled
3. Colour of flower- which is purple or white
4. Position of flowers (A) – which are axial or terminal
5. Length of the stem (T) – which are tall or dwarf
6. Form of ripe pods (I) – which are inflated or constricted
7. Colour of unripe pods (G) – which are green or yellow
Thus, the option-seed texture is the correct answer.
