What are Haploid And Diploid Cells?
sammy [17]
Diploid cells contain 2 sets of the same DNA where as haploid contains one set.....so our normal cells in our body (somatic cells) are diploid however our sex cells(gametic cells) which are the egg of a woman and sperm from a guy are only haploid which means they have only 1 copy of DNA......this is because they fuse with one another and add their DNA together to make a diploid cell

A woman who is a carrier for hemophilia marries a hemophiliac man. What will be their children’s possible phenotypes?
Morgarella [4.7K]

Answer:

Hemophilia is a sex-linked recessive disorder in which a person's blood do not clots and he can bleed to death even after minor injuries because blood will keep running due to a small cut.

It is a recessive trait which means that even if one normal gene is present along with Hemophiliac gene, the person will not have the disease and he will be the carrier.

Question: What will be their children’s possible phenotypes?

If a woman who is a carrier for hemophilia marries a hemophiliac man, their genotypes can be denotes as :

Here H, indicate normal gene and small h indicate defected (hemophilia) gene.

Parents:                      XHXh                   X           XhY

Offspring:                   XHXh : XHY:  XhXh:  XhY

Phenotype of offspring:

XHXh:  The child will be daughter and normal (25 % chances)

XHY:     The child will be son and normal (25 % chances)

XhXh:   The child will be girl and Hemophiliac (25 % chances)

XhY:      The child will be son and Hemophiliac (25 % chances)

Hope it helps!

What is an example of why the process of photosynthesis is important to life on earth
ruslelena [56]

Explanation:

Photosynthesis is a chemical pathway that’s integral to producing energy in plants and other primary producers. Energy stored within carbohydrates, like molecules of glucose is produced from light, water and carbon dioxide while oxygen is released.

6CO2 + 6H20 + (energy) → C6H12O6 + 6O2 Carbon dioxide + water + energy

Carbohydrates molecules that supply energy and provide support; they consist of mainly sugars or starches in long chains and rings to form monosaccharide monomers. Inclusive of monosaccharides, disaccharides and polysaccharides (which describes the type of bonding and the degree of complexity of the polymers), their basic makeup comprises C, H, O -with many polar OH groups.

The energy they store, is required by all living organisms for biological processes; these undergo respiration, in order to release energy stored within its bonds, in the form of the molecule ATP.
