Answer:What can we observe in order to visualize mendel's law of segregation ?
During meiosis I the homologous chromosomes separate.
Explanation:As stated by mendelev that "allele pairs separate or segregate during gamete formation..."
meiosis is the basis in the formation of sex cells.
we can see like wise in meiosis I as homologous chromosomes separates.
Answer:
Nitrogenous bases contain the genetic information, their amount is variable among different species, and the arrangement of these bases is also variable among different species
Explanation:
Both Watson-Crick and Pauling's DNA models considered that DNA nitrogenous bases (i.e., Adenine, Cytosine, Thymine and Guanine) contain the genetic information that determines the characteristics of living organisms. Moreover, both DNA models also considered that nitrogenous base composition varies between species, as well as the arrangement of these bases in the DNA chain also varies between species. Based on these features, Linus Pauling considered that a model where nitrogenous bases would be arranged on the outside of the DNA molecule would be easier for the DNA molecule to be replicated, transcribed, or repaired. Although incorrect, Pauling's DNA triple helix model was fundamental to develop the helical (double-stranded) structure of DNA, which was finally discovered by Watson and Crick in 1953.
Answer: The color of the iris is the example of polygenic inheritance.
Explanation:
Polygenic inheritance can be defined as the inheritance in which one trait is controlled by the two or more than two genes. The color of the skin, color of iris, weight and height are polygenic traits. The color of the iris is the polygenic trait the number of genes responsible for this are unknown but these genes are responsible for the synthesis of melanin pigment imparting color to the iris. OCA2 and HERC2 are the chief genes present on chromosome 15 responsible for this trait. Dark brown and black eyes are expected to have more amount of melanin as compared to the green and hazel eyes.
