If a spinach plant with flat (FF) green (GG) leaves is crossed (pollination and fertilization occur) with another spinach plant

with crinkly (ff) purple (gg) leaves, what alleles and traits will the offspring inherit?

Answer:

The offsprings of this cross will inherit the flat (F) and green (G) alleles from the first parent and also the crinkly (f) and purple (g) alleles from the second parent. However, the offsprings will only inherit the flat, green traits.

Explanation:

This question involves two different genes coding for leaf shape and leaf color respectively. The alleles for flat (F) and green (G) leaves are dominant over the alleles for crinkly (f) and purple (g) leaves.

According to this question, If a spinach plant with flat (FF) green (GG) leaves is crossed with another spinach plant with crinkly (ff) purple (gg) leaves, all the offsprings in the F1 generation will possess a FfGg heterozygous genotype.

This genotype means that the F1 offsprings of this cross will inherit the flat (F) and green (G) alleles from the first parent and also the crinkly (f) and purple (g) alleles from the second parent. However, they will only inherit the flat, green traits because they are dominant over the crinkly and purple trait.

Vlad1618 [11]

Answer:

B. It was necessary that each of the two phage components, DNA and protein, be identifiable upon recovery at the end of the experiment.

Explanation:

Hershey and Martha Chase used radiolabeled the DNA of some of the bacteriophage cells with phosphorus (32P). They radiolabeled the sulfur (35S) of the coat protein in the second batch of the phage cells. They infected some of the bacterial cells with phage having radiolabeled DNA while the other <em>E. coli</em> cells were infected with the phage carrying radiolabeled coat protein. This allowed the clear identification of the radiolabelled molecule (DNA or protein) present in the host cell.

They observed that the <em>E. coli </em>cells infected with phage having radiolabeled DNA exhibited the radioactivity while the other batch of the host cell did not show it.

Growth and repair involve primarily what type of reactions?1. catabolic2. It depends on which body or cell part is growing or re
Rus_ich [418]

Answer:

Anabolic.

Explanation:

The metabolic reactions of the body are important to maintain the physiology and homeostasis of the body. Two main types of reaction in the body are catabolic reactions and anabolic reactions.

The anabolic reaction is the reactions that are involved in the formation of the large molecules from the simpler substances. The anabolic reactions are involved in the growth and repair process as complex protein and factors are required that can only be obtained by the anabolic reactions.

Thus, the correct answer is option (3).

The brown-eye allele is dominant over blue-eye allele. A couple currently has 3 children with brown eyes. What is the probabilit
MissTica

Answer:

The correct answer is: 25 %

Explanation:

According to Mandel's law of inheritance, the dominant allele masks the expression of the recessive allele if present together. If a couple has 3 children with brown eyes. In a monohybrid cross, the ideal phenotypic ratio of the offsprings is 3: 1 or in other words, the dominant character chances to appear is 75% in phenotype.

So, by the law of dominance of monohybrid cross the chances of the fourth child to develop blue eyes is 25%.

Thus, the correct answer is : 25 %.

Choose appropriate way(s) that steep cliffs might impact people living nearby:
dusya [7]

People living nearby steep cliffs can impact them in different ways, the people nearby will affect them into having a decrease area available to grow crops as it is dangerous to even grow crops in areas like it, another thing is, there will be an increase of landslide hazard as they are in a steep cliff. Having steep cliffs are dangerous and will only cause them a disadvantage.
