A man is heterozygous for sickle cell anemia and homozygous dominant for familial hypercholesterolemia. Knowing that these genes

are located on different chromosomes and using the information below, predict his possible sperm. Sickle Cell Anemia A=Normal hemoglobin a=Abnormal hemoglobin (Sickle Cell) B=Familial Hypercholesterolemia (abnormal LDL protein receptor) b=Normal LDL protein receptor)

Because of the law of independent assortment, alleles on different chromosomes sort independently of one another during the formation of sex cells. Because of the law of segregation, alleles of the same gene do not end up in the same sex cell during meiosis.

The answer <span>is AB and aB

<span>A man is heterozygous for sickle cell anemia: Aa
</span></span>A man is <span>homozygous dominant for familial hypercholesterolemia: BB

So, his genotype is AaBB. He will give only one allele of two for each gene.
He can have 2 different combinations in sperm cells:
- AB
- aB</span>

Montano1993 [528]
The most probable and most likely answer to this problem would be genetic engineering.

Since this talks about scientists having recently modified the bacteria that cause tooth decay by inserting a fragment of DNA into the bacteria's DNA that prevents it from producing lactic acid, it has now altered the genetic composition of the bacteria. Genetically engineering bacteria and viruses have their advantages and, of course, disadvantages, either direct ones or long term ones. Genetic engineering would prove that it would be one of the many weapons that we could use to counter problems in the coming future.

Match each organism with its phylum Pines Ephedra Palm-like plants Trees with fan-shaped leaves A. Gnetophyta B. Ginkgophyta C.
solong [7]

Answer:

Ginkgophyta

Explanation:

Gymnosperms are cone-bearing trees or Woody plants, which do not different greatly in their structure from the Woody angiosperms. Gymnosperms do not produce flowers but as seed plants that bear their seeds on scale-like leaves which are arranged spirally to form cones. The seeds are termed naked seeds because they are exposed to the air on the surfaces of the cone scales.

Gymnpsperms are grouped into four major divisions namely:

*Ginkgophyta

*Cycadophyta

*Corniferophyta

*Gnetophyta

1)DIVISION GINKGOPHYTA:The ginkgo tree cared maiden hair is the only surviving member of this division. It is found in the Orient(China and Japan) where it is cultivated as an ornamental tree because of the fan-like leaves. The leaves are *fan-shaped* with long petrioles.

2)DIVISION CYCADOPHYTA:The cycads abound in the tropics, mainly as ornamental plants. They are *palm tree-like* plants with a crowded crown of palm fronds.The leaves of Cuba's are deep green,waxy with large petioles.

DIVISION CONIFEROPHYTA:This is the largest group of Gymnosperms as it includes some of most economically exploited plants such as *pines* and Jupiter's. The pine tree is important as Christmas tree and conifers are generally important in the production of wood and paper

DIVISION GNETOPHYTA:This is the group of very unique Gymnosperms made up of three genera:Gnetum,*Ephedra* and Welwitschia.

Ephedra is a profusely branched shrub found in desert regions. It has whorl-like, scale-like, or needle -like leaves and jointed stem.

Hence, matching each with its phylum, we have:

Gingkophyta:Fan-shaped leaves

Cycadophyta-Palm-like leaves

Coniferophyta:Pine

Gnetophyta:Ephedra

Svetlanka [38]

Answer:

Option D, a test for the presence of cells that contain DNA

Explanation:

As we know all living organisms are made up of cells and DNA is the basic genetic material that codes for protein and traits with an organism. If even a single cell with DNA is detected on the extraterrestrial planet then it will be clear that it has life on it or the environmental conditions are favorable to support life. Cells are microscopic and hence can be seen through microscope which can be installed easily on a probe.

Hence, option D is correct
