If each parent has two sets of genes and chromosomes why do their offspring receive only one set from each parent

Answers

Answer:

Because we are diploid humans, and we have 2 chromosomes per set. We get one set from our mother, and one from out father. Each of the sets from our parents are haploid (1 ), so together they are a diploid(2) set. I can go into depth more with meiosis if you need.

some scientists predict that if global warming continues over the next few centuries, melting of the polar ice caps will rise the level of the oceans causing some peninsulas to become islands. how might this change eventually affect the species that live on these peninsulas?

Answers

Answer:

As global warming causes more snow and ice to melt each summer, the ocean and land that were underneath the ice are exposed at the Earth's surface. Because they are darker in color, the ocean and land absorb more incoming solar radiation, and then release the heat to the atmosphere.

3. In 1981, a stray black cat with unusual curled-back ears was adopted by a family in California. Suppose you were the person who owned the first "curl" cat, and wanted to develop it into its own breed. How would you determine whether the allele for curled ears is dominant or recessive? Why does it make a difference for breeders whether an allele for a trait is dominant or recessive?

Answers

It is possible to determine whether the allele for curled ears is dominant or recessive by performing a test cross. It is fundamental for breeders because desired traits show differential patterns of inheritance.

In a diploid (2n) organism, a given gene locus exhibit two different variants or forms called 'alleles'.

An individual is homo-zygous when both alleles for a given gene locus are the same, while an individual is heterozygous when alleles are different.

In cases of complete dominance, the expression of the recessive allele is completely masked in heterozygous individuals.

A breeder is a professional who performs genetic crosses between different organisms in order to obtain offspring (eg., plants, animals, etc) with desired phenotypic features.

A test cross is a type of cross that breeders use to determine whether an allele is dominant or recessive (in this case, the allele for curled ears).

In a test cross, the organism that is a carrier of the unidentified allele is crossed with another organism that is believed to be homo-zygous for the recessive trait, and then the proportion of offspring is examined.

What are the three layers that make up the body of a Cnidarian?

A. endoderm, mesoderm, ectoderm
B. endoderm, mesoglea, ectoderm
C. ectoderm, mesoderm, mesoglea
D. endoderm, mesoglea, epidermis

Answers

The endoderm is the inner layer ('endo' for 'within'), and the ectoderm is the outer layer ('ecto' for 'outer'). If there was a third layer it would be called the mesoderm, 'meso' for 'middle'. But cnidarians do not have this middle layer. Germ layers develop during gastrulation.

How can accidental transfer of DNA impact a crime scene investigation? In addition, explain why accidental DNA transfer cannot be used as an excuse to throw away all DNA evidence found at a crime scene?

Answers

Answer:

orensically valuable DNA can be found on evidence that is decades old. However, several factors can affect the DNA left at a crime scene, including environmental factors (e.g., heat, sunlight, moisture, bacteria, and mold). Therefore, not all DNA evidence will result in a usable DNA profile.

-. What describes the conversion of ADP to ATP?

Answers

Answer:

Two processes convert ADP into ATP: 1) substrate-level phosphorylation; and 2) chemiosmosis. Substrate-level phosphorylation occurs in the cytoplasm when an enzyme attaches a third phosphate to the ADP (both ADP and the phosphates are the substrates on which the enzyme acts).

Dont have a question A genetics student is studying a plant that seems to have two Mendelian traits, flower color (red is dominant, and yellow is recessive) and seed color (brown is dominant, and green is recessive).Use the Table button to create a Punnet square. Your Punnet square should show the possible offspring from one parent that is homologous recessive for both traits and the other parent that is heterogeneous for both traits. For flower color, use F and f, and for seed color, use S and s.Then, based on the Punnet square you made, answer this question: What are the chances that the offspring will have the red flower, green seed phenotype?
