A cross between two plants that both have yellow flowers produces 80 offspring plants, of which 38 have yellow flowers, 22 have

red flowers, and 20 have white flowers. If one assumes that this varia- tion in color is due to inheritance at a single locus, what is the genotype associated with each flower color, and how can you describe the inheritance of flower color?

Always start with the genotypic ratios, because they'll be the same. Since hidden variation is popping out, you can assume that both of the parents are heterozygous. The problems you get will be the F2 ratio of the cross between two homozygous individuals.

1:2:1 is the genotypic ratio for one locus. AA:Aa:aa.

1:2:1 is the phenotypic ratio for incomplete dominance. Incomplete dominance means that the heterozygote expresses differently from either homozygote.

3:1 is the phenotypic ratio for complete dominance.

2:1 is the phenotypic ratio for lethal recessive.

Julli [10]

Answer:

Speciation was allopatric or peripatric, but would depend on the number of individuals that dispersed from the original populations.

Explanation:

  • There are two types of speciation: allopatric and peripatric.
  • Allopatric speciation occurs when the species of same population gets isolated that results in lack of gene flow.
  • From the isolated population, new species are formed then it is known as the peripatric speciation.
  • All these isolation of populations and formation of new species depends upon the initial or original group of species that was dispersed.

Which virus is correctly matched with its structure?
yan [13]

Answer:

B. polio—polyhedral shape

Explanation:

A virus is a small parasite which cannot self reproduce. For a virus to produce more viruses, it uses the cell to duplicate itself. Viruses contain RNA or DNA as their genetic material.

Poliovirus is composed of an RNA genetic material and it is responsible for Polio. Polio leads to paralysis and is transmitted through contaminated water or food, or contact with an infected person.

The shape of Poliovirus is formed by polyhedral (many-sided) shell or capsid.
