If G=yellow seeds and g=green seeds, a) predict the genotypic and phenotypic ratios of a cross between a heterozygote and a homo

zygous recessive individual. b) show the genotypic and phenotypic ratios of the F2 of a cross between a gg and GG individual.

Answer:

a) Genotype ratio= 1/2 Gg: 1/2 gg

Phenotype ratio = 1/2 yellow seeds: 1/2 green seeds

b) Genotype ratio= 1/4 GG : 1/2 Gg: 1/4 gg

Phenotype ratio= 3/4 yellow seeds : 1/4 green seeds

Explanation:

a) Genotype of heterozygote parent plant = Gg

Genotype of homozygous recessive parent plant= gg

A cross between Gg x gg gives progeny in following ratio= 1/2 Gg (yellow seeds) : 1/2 gg (green seeds)

b) Parent plants = GG x gg

F1= Gg

A cross between Gg x Gg would give F2 progeny in following ratio= 1/4 GG (yellow seeds): 1/2 Gg (yellow seeds) : 1/4 (green seeds)

PLS ANSWER QUICK What do you think would happen to each species if the water became too cloudy for sunlight to penetrate?
Vaselesa [24]

Answer:      Turbidity blocks the sunlight that plants need to produce oxygen for fish and other aquatic life. ... One effect is an increase in rooted aquatic plants, since sunlight can now penetrate to greater depths.

In order to initiate transcription in eukaryotes, _______. View Available Hint(s) In order to initiate transcription in eukaryot
laila [671]

Answer:

transcription factors bind to the promoter, and RNA polymerase is then recruited to begin transcribing the gene

Explanation:

The transcription process in eukaryotes happens in 3 stages:

  1. Initiation
  2. Elongation
  3. Termination

The initiation of transcription starts when a set of proteins called the transcription binds to the promoter region of a gene on the coding strand of DNA. Thereafter, the RNA polymerase enzyme binds to the promoter region thereby opening up the double helix structure of the DNA in anticipation of transcription.

During elongation, RNA nucleotides are added to the growing RNA strand in 5' to 3' direction with the DNA unwinding and winding back as the polymerase moves along the coding strand in 3' to 5' direction.

Transcription terminates when the RNA polymerase gets to the end of the gene being transcribed signalled by a sequence of DNA known as the terminator.

<em>Hence, in the illustration, the correct answer would be that the transcription factors bind to the promoter, and RNA polymerase is then recruited to begin transcribing the gene.</em>
