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

Normalization refers to providing opportunities for individuals with disabilities to go to school and participate in education e
zzz [600]

Answer:

Answer is true.

Explanation:

Generally, it has been discovered , that people with disabilities are deprived of their rights to many national or international benefits. This is because , they do not have the abilities to strive or contend physically with able people. And this has made them to settle for anything that is being given to them.

The process of normalization has really helped to put things back to how it should be, and this has really helped the people with disabilities because, they now have access to facilities or things that able people have access to, even without struggling or contending with them. Because, prefrential treatments has been given to them wherever or whenever they have to share amenities with the able people.

PLEASE HELP!!!!! I NEED PERSON GOOD WITH AP BIOLOGY!! I WILL GIVE BRAINLIEST PLS!!!
sergey [27]

Answer:

if crossing over does not occur, the products are parental gametes. If crossing over occurs, the products are recombinant gametes. Meaning they are mixed.

Explanation:

If crossing over doesn't occurs then you wouldn't really mix the 2 parental alleles so you couldn't have a genotype without mixing.

Sorry if im wrong!
