in corn normal kernels are dominant to waxy kernels.if you crossed a waxy kernel plant to a heterozygous normal plant what type

The genotype of the seeds that will be produced are as follows:

  • Nn (2) - normal kernel seeds
  • nn (2) - waxy kernel seeds

<h3>WHAT IS GENETIC CROSS?</h3>

According to this question, a gene coding for kernel shape is involved. Normal kernel (W) is dominant over waxy kernel (w).

If a waxy kernel plant (ww) is crossed with a heterozygous normal (Ww) plant as follows: Ww × ww, the following offsprings will be produced:

  • Ww
  • Ww
  • ww
  • ww

Therefore, the genotype of the seeds that will be produced are as follows:

  • Nn (2) - normal kernel seeds
  • nn (2) - waxy kernel seeds

Why are the two strands of the double helix "perfect and specific compliments"?
77julia77 [94]
Because for the strands to form a double helix the base pairs have to match perfectly (adenine with thymine and cytosine with guanine) in DNA , and if a strand of RNA is paired with a split strand of DNA it goes adenine with uracil and cytosine with guanine (uracil replaces thymine)

Net redox reaction in acetyl CoA formation and the citric acid cycle.
pav-90 [236]

Answer:

Step 1: oxidation of Pyruvate to CO2

Step 2: Reduction of NAD+ to NADH

Step 3: Reduction of FAD to FADH2

The NAD+ and FAD are electron carriers needed during this process

In peas, purple flowers are dominant to white and tall plants are dominant to short. A white and short plant is crossed with a p
Mumz [18]

to understand what the result of these crosses would be like, we need to know what is gene

<h3>Gene</h3><h3 />

The gene is a strand of a DNA molecule (deoxyribonucleic acid), which carries the characteristics that are genetically inherited. They are composed of a sequence of DNA and RNA (ribonucleic acid), responsible for the production and synthesis of proteins in the cell. The gene's greatest attribution, therefore, is to be a store and transmitter of information.

Genes can be classified into:

  • Dominant genes: assume the specific characteristic in the offspring;
  • Recessive genes: manifests itself in the absence of the dominant gene;
  • Structural genes: are those that contain the information that will determine the structure of living beings;
  • Operator gene: acts on the functioning of other genes;
  • Regulatory gene: responsible for controlling the synthesis and transcription of other genes.

<h3 /><h3 />

in genetics, are individuals who have pairs of genes that are identical or different alleles. This means that while the has two identical genes alleles, with the beings the opposite happens, since they have two different genes alleles.

with this information we can say that a white and short plant, when crossed with a plant  for both traits, has 60% of this plant being  with expression of the dominant genes and 40% of being  with expression of the recessive gene.
