Answer:

The phenotypic ratio is 9:3:3:1

Explanation:

<u>Available data</u>:

  • green color (G-) is dominant to yellow color (gg)
  • G allele is dominant. g allele is recessive
  • two leaves (T-) are dominant to three (tt)
  • T allele is dominant, t allele is recessive

Cross: between two plants that are heterozygous green and heterozygous tall

Parentals)       GgTt      x      GgTt

Phenotype) Green color     Green color

                    Two petals      Two petals

Gametes)  GT, Gt, gT, gt   GT, Gt, gT, gt

Punnett Square)      GT          Gt         gT         gt

                      GT    GGTT    GGTt    GgTT      GgTt

                      Gt     GGTt      GGtt     GgTT     Ggtt

                      gT    GgTT       GgTt     ggTT     ggTt

                      gt     GgTt        Ggtt       ggTt     ggtt

F1) Genotype:

    1/16 GGTT

    2/16 GGTt

    1/16 GGtt

    2/16 GgTT

    4/16 GgTt

    2/16 Ggtt

    1/16  ggTT

    2/16 ggTt

    1/16 ggtt

     <u>Phenotype</u>:

    9/16 G-T- --> Green-colored and two-leaved plant

    3/16 G-tt ----> Green-colores and three-leaved plant

    3/16 ggT---> Yelow-colores and two-leaved plant

    1/16 ggtt ---> Yeloow-colores and three-leaved plant

if there were no suppression of dna replication between meiotic divisions but cytokinesis proceeded normally, what is the most l
sergiy2304 [10]
The answer is 4 diploid cells.

Meiosis is a cell division which results in the reduction of chromosome number by half - from diploid to haploid - in daughter cells. It consists of meiosis I and meiosis II. Meiosis I produces <em>two haploid cells</em>.<span> Meiosis II is analogous to mitosis, so in total, meiosis results in four haploid cells. This is achieved through suppression of DNA replication between two meiotic divisions.
If there were no </span><span>suppression of DNA replication, then meiosis I would produce <em>two diploid cells</em>, and after meiosis II there will be four diploid cells.</span>

masya89 [10]

<u>Nucleic Acid, and Protein</u> are the class of biomolecule which are the two main ingredients in plant fertilizer.

Biomolecules- A chemical substance that is present in living things is called a biomolecule. These consist mostly of substances with the chemical elements carbon, hydrogen, oxygen, nitrogen, sulfur, and phosphorus. The building blocks of life, biomolecules serve crucial roles in all living things.

Fertilizer- Any product or material given to soil to encourage plant development is referred to as fertilizer. There are many different types of fertilizers, and the majority of them include potassium, phosphorus, and nitrogen (N) (K). In actuality, the package of fertilizers bought in supermarkets lists the N-P-K ratio.
