What’s the relationship between homozygous and hybrid?

1 answer:

7 0

Homozygous traits are either a combination of the same two dominant alleles or the same two recessive alleles. A hybrid trait is also known as a heterozygous trait, and is the pairing of a dominant and recessive allele.

1. Describe the clamming industry in the 1970 and how it used to be a serious business.

attashe74 [19]

The clamming industry in Long Island used to be very lucrative, raking in as much as $100 Million annually. By the 1970s, it had shrunk to less that $40 million per annum.

<h3>What was to blame for the decline according to the article mentioned above?</h3>

2. According to the New York Times Article of 1985, the reason for the steep decline in the value of the Clamming industry was related to the loss of confidence in the health safety of eating raw shellfish.

3. According to the remarkable discovery of the "208 Study", it was discovered that there was a connection between land use and underground water quality. It was also discovered there was a negative impact of dumping sewers in the ocean on the production of shellfish

4. Some of the solutions that were proposed to manage this situation are:

Using sewers to collect effluents into a septic treatment plant. rather than dumping them into the ocean.
The implementation of secondary sewage treatment supplemented by ocean disposal of the effluents and
Monitoring the salinity levels of the clamp ecosystem.

Meiosis Foldable Activity 515.2

Aleksandr-060686 [28]

Explanation:

During the process of prophase I, the nuclear envelope containing chromosomes has only partly broken down homologous chromosomes are joined together by proteins and a complex or pairing call synapsis- corresponding genes on sister chromatids are aligned precisely.

The syanapsis allows for crossing over which is the exchange of segments of chromosome, between non-sister homologous or similar chromatids crossing over happens at chiasmata, the point where non-sister chromosomes are joined.

Further Explanation:

All the genetic information within the eukaryotic cell is stored within the nucleus as helical DNA. This DNA is tightly wound around histones as chromosomes. In meiosis, the number of chromosomes (2n) is halved to 23 chromosomes (haploid number)through meiotic divisions, producing 4 haploid (n) germ cells or gametes (sperm or eggs), each containing half the number of chromosomes as its parent cell.

In Meiosis I

homologs pair off into bivalents
At crossing over: the exchange of segments of chromosome, between non-sister homologous or similar chromatids crossing over happens at chiasmata, the point where non-sister chromosomes are joined in prophase I forming bivalents; tetrads are formed.
Spindle fibers from centrioles join sister chromatids together at their centromeres in metaphase I, pulling them to the equator of the cell;
then, in anaphase I, while joined, they are pulled to opposite sides of the cell; the cell body splits and the nuclear envelope reforms in telophase I

In Meiosis II...

Later, in prophase II, the nuclear envelope disintegrates and mitotic spindle fibers are formed
independent assortment occurs. in metaphase II of meiosis: spindle fibers attach to centromeres, chromatids align independently at the equator. Genes segregate independently into new combinations as sister chromatids are pulled apart by their centromeres in anaphase II
in telophase II the cells' nuclei and membrane are then formed with each containing the haploid number (n)
Following the formation of gametes in the last stage, randomized fertilization occurs in sexual reproduction sperm cells fertilize an ovum to form a zygote. This occurs randomly by chance, to result in a complete set of chromosomes 2n, that is a novel combination of half each parent's number of chromosomes
