Gametes are the sex haploid cells produced by a diploid germ cell through meiotic division. Parent 1) Gamete 1: W, gamete 2: W, gamete 3: W, gamete 4: W. Parent 2) Gamete 1: w, gamete 2: w, gamete 3: w, gamete 4: w.

Gametes are sex haploid cells (n) that result from meiotic division. During meiosis, a diploid germ cells divides into four haploid cell -the gametes-.

Each gamete carries half the genetic material of its parental cell. It contains only one of the alleles.

In the exposed example, we need to determine the parental gametes of two snapdragon plants concerning flower color.

Snapdragon plants express incomplete dominance for flower color, meaning that

First, we need to determine the parental genotype of a cross between a homozygous plant for white flowers with a homozygous plant for red flowers.

Parental 1: WW ⇒ White phenotype

Parental 2: ww ⇒ Red phenotype

The whole progeny resulting from this cross will be pink, Ww.

Now, we need to determine the parental gametes.

The germ cell is WW. This cell divides into four haploid cells carrying only one of the alleles. So,

Gamete 1: W

Gamete 2: W

Gamete 3: W

Gamete 4: W

The germ cell is ww. Repeating the same reasoning as before, this diploid cell divides into four haploid cells carrying only one of the alleles. So,

Gamete 1: w

Gamete 2: w

Gamete 3: w

Gamete 4: w

Now we can make the Punnett square representing the cross and using these gametes.

When a sperm fertilizes an egg, the resulting fertilized egg, or zygote, has a complete set of homologous pairs of chromosomes, with one set inherited from the mother's egg and one set inherited from the father's sperm. This happens because the egg and sperm each contain only one copy of each chromosome, rather than the full set of two copies that are found in the cells of the body. When the egg and sperm fuse, the resulting zygote has a full complement of chromosomes, with one copy of each chromosome from each parent.

Microplastics are abundant and widespread in the marine environment. They are a contaminant of global environmental and economic concern. Due to their small size a wide range of marine species, including zooplankton can ingest them. Research has shown that microplastics are readily ingested by several zooplankton taxa, with associated negative impacts on biological processes. Zooplankton is a crucial food source for many secondary consumers, consequently this represents a route whereby microplastic could enter the food web and transfer up the trophic levels. In this review we aim to: 1) evaluate the current knowledge base regarding microplastic ingestion by zooplankton in both the laboratory and the field; and 2) summarise the factors which contribute to the bioavailability of microplastics to zooplankton. Current literature shows that microplastic ingestion has been recorded in 39 zooplankton species from 28 taxonomic orders including holo- and meroplanktonic species. The majority of studies occurred under laboratory conditions and negative effects were reported in ten studies (45%) demonstrating effects on feeding behaviour, growth, development, reproduction and lifespan. In contrast, three studies (14%) reported no negative effects from microplastic ingestion. Several physical and biological factors can influence the bioavailability of microplastics to zooplankton, such as size, shape, age and abundance. We identified that microplastics used in experiments are often different to those quantified in the marine environment, particularly in terms of concentration, shape, type and age. We therefore suggest that future research should include microplastics that are more representative of those found in the marine environment at relevant concentrations. Additionally, investigating the effects of microplastic ingestion on a broader range of zooplankton species and life stages, will help to answer key knowledge gaps regarding the effect of microplastic on recruitment, species populations and ultimately broader economic consequences such as impacts on shell- and finfish stocks.

High humidity and rainfall: Tropical rain forests are characterized by high humidity and high rainfall, typically receiving more than 200 cm (80 inches) of rain per year. This high rainfall is due to the presence of warm, moist air that is constantly being carried inland from the oceans by trade winds.

Dense vegetation: Tropical rain forests are characterized by dense vegetation, including a wide variety of trees, vines, and other plants. The canopy of the rain forest, made up of the tops of the tallest trees, can be up to 50 meters (165 feet) above the ground.

High species diversity: Tropical rain forests are home to a wide variety of plant and animal species, many of which are found nowhere else on Earth. These ecosystems are thought to contain more than half of all the species of plants, animals, and insects on the planet.

Explanation:

Answer:

Explanation:

Protein synthesis, or translation, is the process by which cells synthesize proteins from amino acids using the information stored in their DNA. In Escherichia coli cells, protein synthesis occurs in the ribosomes, which are small, specialized organelles that translate the genetic code in mRNA into a sequence of amino acids.

The time it takes to synthesize a protein from 20 amino acids will depend on a number of factors, including the size and complexity of the protein, the efficiency of the ribosomes, and the availability of the necessary amino acids and other resources. In general, the rate of protein synthesis in E. coli cells is relatively fast, with some ribosomes able to synthesize up to 20 amino acids per second. This means that it could potentially take only a few seconds to synthesize a small protein consisting of 20 amino acids. However, it is important to note that this is just a rough estimate and the actual time may vary depending on the specific circumstances.

Explanation:

Recently had this on one of my quizzes :)

Mendel crossed pure bred green seeded and pure bred yellow seeded plants.

Mendel's first law is the law of segregation in which during gamete formation each member of a gamete pair separates from the other member to form the genetic constitution of the gamete.

The second law of Mendel is the law of independent assortment which describes how alleles of different genes independently segregate from each other during the formation of gametes.

Mendel's third law was the law of inheritance which states that the separation of an allele pair into two daughter cells during the second phase of meiosis does not affect the way in which the other allele pair separates or segregates.

Mendel's laws are important because they allow us to understand how characters are inherited and what determines the phenotypes that are obtained by different individuals. When Mendel crossed pure bred green seeded and pure bred yellow seeded plants, these traits don't blend during his discovery.

Thus, Mendel crossed pure bred green seeded and pure bred yellow seeded plants.
