Answer:

1/2 of an answer is zero answer.

Explanation:

The two main types of nucleic acids are DNA and RNA. Both DNA and RNA are made from nucleotides, each containing a five-carbon sugar backbone, a phosphate group, and a nitrogen base. DNA provides the code for the cell's activities, while RNA converts that code into proteins to carry out cellular functions.

If G=yellow seeds and g=green seeds, a) predict the genotypic and phenotypic ratios of a cross between a heterozygote and a homo
Schach [20]

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)

3. Which of the following is an accurate description of mitosis and meiosis? A. Meiosis produces two haploid daughter cells, whi
maria [59]

The correct answer is - B. Mitosis produces two diploid daughter cells, while meiosis produces four haploid daughter cells.

The processes of mitosis and meiosis are often confused with one another, mostly because of the similarity in their names.

The mitosis is a type of cell division where the end result is two daughter cells, each of the cells has the same number and kind of chromosomes as the parent nucleus. Thus is typical for the growth of tissue.

The meiosis is a type of cell division where the end result is four daughter cells, each of the cells having half the number of chromosomes of the parent nucleus. This is typical for the gametes and the plant spores.
