Achondroplasia is an autosomal dominant genetic disorder in humans. If a man with Achondroplasia ( heterozygous) and a normal wo
tresset_1 [31]

Answer and Explanation:

Achondroplasia is a form of dwarfism that affects the formation of cartilage; early in development, most of the skeleton is comprised of cartilage. Cartilage is a type of flexible, tough tissue; in achondroplasia ossification (conversion of cartilage to bone) is affected. Symptoms include an enlarged head, shorter upper and lower limbs, and limited motion at the elbow.

Punnett squares are illustrations that display the product of hybrid trait crosses by genetic breeding.

For this cross...

Assuming Achondroplasia= dominant

Parent generation or P generation:

gametes: An → Achondroplasia dominant (A), No Achondroplasia recessive (n)

Heterozygousity describes the allelic makeup; these traits comprise two varying forms of a  gene. However, homozygous traits comprise identical forms of the gene.

Male: An  →  with Achondroplasia

Female: nn → without Achondroplasia

genotypes and phenotypes for parent and offspring...

Assuming heterozygousity of the male , for the cross

P generation:                         An × nn

                          Achondroplasia   × No Achondroplasia

F1 generation:

genotype:                      An × nn       ...(from punnet square)

phenotype:          2 with Achondroplasia ; 2 without

∴ 50% are genotypically heterozygous while 50% is homozygous , 2 with Achondroplasia ; 2 without

Explanation:

Migration refers to the movement from one region to another

Neuronal Migration refers to the movement of the neurons from their origin (brain center) to their final positions.

Example Neuron 4591 migrated to the part of brain that con trols logic whereas  Neuron 4592 migrated to the region of the brain that controls emotions.

The migration can be radial or tangential.

Which of the following predictions about global climate is directly related to an increase in the burning of fossil fuels? a. in
alexandr402 [8]
The appropriate answer is c. global warming. Global warming is an increase in the global temperature caused by the increased use of fossil fuels. Using fossil fuels since the industrial revolution has pumped extra carbon dioxide in the atmosphere than what would actually enter from natural processes. This extra carbon dioxide is increasing the green house effect and causing the temperature to increase.
