A daughter has hemophilia a recessive sex-linked what are the possible genotypes of her parents
marishachu [46]

Answer:

If a female child has hemophilia it is possible that the mother is a carrier of the hemophilia gene and the father has hemophilia.

Explanation:

  • A daughter gets X chromosome from both her parents.
  • It is generally seen in males.
  • Hemophilia is generally recessive in females.They act as carriers of hemophilia. This occurs because they have a X chromosome that dominates the hemophilia affected gene that they inherit from any parent.
  • But, if both the parents have faulty genes ,i.e the mother is the carrier of the gene and the father is hemophiliac, then the chances are the daughter has hemophilia too.

Describe the importance of biomes such as forests, freshwater, and marine biomes? How have human actions affected these biomes?
Allisa [31]

Forest biome:  It gives us medicinal plants, woods for commercial purpose. Forests provides us rubber and fibers that is very important for the industries for making various products. They also contribute to perform ecological  functions such as carbon storage, nutrient cycling, water and air purification. It also provides habitat to the wildlife.

Freshwater biome:  We use fresh water for drinking water, irrigation, sanitation systems, and in industrial factories. Water used from groundwater, rivers and lakes is regained by rain and snowfall.

Marine biome:  It serves huge amount of oxygen into the environment and absorbs the atmospheric carbon dioxide.

As a result of the activity of human there is a significant decrease in the number of trees. The products now used are synthetically made which were made up of natural fibers previously. The water source such as rivers, lakes, and ponds are polluted due to which many water borne diseases are increasing day by day. The accumulation of waste which are found in marine biome are reducing the number of flora present inside marine ecosystem.

you will need to put your model chromosomes back together for the next part of this activity. the diagram shows how your partner
timurjin [86]

Sister chromatids have different alleles although carry same genes on same loci. So if it doesn't happen so, like if there are same alleles on sister chromatids then there is a problem in its formation. i.e., male and female alleles haven't contributed equally ( may be an error during their segregation process ). And obviously it doesn't happen in a real cell so we must understand this point. Because normally whenever it happens there's one half from the male and one half  from the female. (i.e. maternal and paternal alleles contribute equally).

I hope you get the answer!!!
