Why does the expected genotypic ration often differ from the expected phenotypic ratio resulting from monohybrid cross

Biology
1 answer:
artcher [175]3 years ago
5 0

Answer:

The genotypic ratio and phenotypic ratio are different when a monohybrid cross is done because multiple genotypes often result in the same phenotype.

Match the numbered terms to the description that follows. Choose all appropriate terms. A prokaryote that obtains both energy an
Lera25 [3.4K]

Answer:

Answer is option (2) and (4).

Prokaryotes that obtain both energy and carbon as they decomposes dead organisms - heterotroph and chemotroph.

Explanation:

(1) Autotrophs or Producers - Organisms that produce their own food and get the energy to make food from inorganic sources or sunlight. They are the base level of the energy pyramid of an ecosystem. The existence of all other organisms depends on autotrophs as they provide fuel for others. Examples of autotrophs are green algae, all plants, photosynthetic bacteria, etc.

(2) Heterotrophs or Consumers - Organisms that consume autotrophs or other heterotrophs since they cannot produce their own food. They absorb nutrition from other organic carbon sources such as plant or animal matter. The examples of heterotrophs are fungi, all animals, many protists and bacteria.

(3) Phototrophs - Organisms that capture photons from light and convert it to chemical energy to carry out different cellular processes.

  • Photoautotrophs (holophytic organisms) are autotrophs that carry out photosynthesis in which carbon dioxide and water are converted into organic compounds (glucose) using energy from sunlight. Plants, algae, photosynthetic bacteria are examples.
  • Photoheterotrophs depend on sunlight for their energy and produce ATP through photophosphorylation. Their source of carbon is organic compounds such as carbohydrates, fatty acids, etc obtained from the environment and do not rely on carbon dioxide. Examples include green non-sulfur bacteria, purple non-sulfur bacteria, heliobacteria, etc.

(4) Chemotrophs - Organisms that obtain energy by breaking down or oxidation of organic or inorganic molecules such as ammonia,  carbohydrates, molecular hydrogen, sulfur, hydrogen sulfide, ferrous iron, etc through chemosynthesis.

  • Chemoautotrophs synthesize organic compounds from carbon dioxide using the energy derived from chemical reactions. Most of them are found in deep water environments that receive no sunlight. Cyanobacteria, sulfur-oxidizing bacteria, iron-oxidizing bacteria, nitrogen-fixing bacteria, etc are examples.
  • Chemoheterotroph uses inorganic or organic energy sources as they can not synthesize their own organic compounds. Chemolithoheterotroph uses inorganic energy sources (sulfur, ferrous iron, etc) and chemoorganoheterotroph uses organic energy sources (carbohydrates, proteins, lipids, etc). Examples of chemoheterotrophs include most fungi and animals.

Select all that apply.
stira [4]

Answer:

The correct answers would be maintain chromosome number through generations  and cause genetic variations by recombination.

In Meiosis a cell divides into four daughter cells all of which have half the number of chromosomes present in a parent cell.

It helps in the formation of gametes in sexually reproducing organisms.

These gametes (one from father and one from mother) fuse together to form a zygote. It re-established the chromosomal number as that of the parent.

In absence of meiosis, the chromosomal number would have doubled after each generation.

In addition, the meiosis also increases the genetic variation among the population with the help of crossing over which occurs during the pachytene stage of prophase I.

During this event, genetic information is exchanged between the non-sister chromatids of the homologous chromosomes. It produces a new combinations of genes that are different from either parent.

Which of the following is NOT a density-dependent factor affecting population growth?
sveta [45]

B

<u>Temperature</u> is NOT a density-dependent factor affecting population growth

Explanation:

Density-dependent factors mean variables that are affected by the density of the population. The opposite of density-depend is density-independent factors. These are those variables that affect the density of the population but are not affected by the density of the population.

In this case, temperatures are not affected by the density of the population. However, temperatures affect the density of the population. Most individuals can only survive within an optimal temperature range.

The rest of the choices are density-dependent variables
