Answer:
Explanation:
From the given information:
Since the parent are normal; Let assume that their trait is Pp
The affected sister will be recessive in nature, so the trait will be pp
Now, the husband who is the groom will be a carrier with a probability of 2/3 since her sister is affected.
Also, the wife will be carrying a heterozygous trait since she is normal as well.
However, using Hardy-Weinberg assumption:
q = 0.02
Recall that:
Thus,
2pq = 0.0392
Finally, the required probability that there will be an affected offspring amongst the family is:
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
