Question

25. Mendel's factors undergo segregation and independent assortment. How is this illustrated in the chromosomes during Meiosis I? 26. Explain how these inheritance patterns are considered non-Mendelian. Incomplete Dominance . Multiple Alleles • Codominance X-linked Linkage . Pedigrees - Genetic Disorders 27. What is non-disjunction and how does it affect the chromosome distribution during meiosis? 28. What is a karyotype and what does it allow you to do? 29. Fill in the circles and squares to illustrate the following inheritance patterns (a) X-linked, (b) autosomal recessive, and (c) autosomal dominant. Make a Punnett Square that fits the Pedigree you drew. What is it about the patterns that place them in those specific categories? TO Oo oo O O O O

Answer 1

Q.48. CRISPR Cas9 :- it is powerful tool for editing genomes. Scientists used this because it easily changes DNA sequence and modified gene function,

Cas9 or CRISPR is an enzyme that acts like a pair of molecular scissors, they are capable of / used for cutting strands of DNA.

Scientists used this for control which gene expressed in plants animal even human. To delete undesirable traits and potentially add desirable traits.

The system of CRISPR Cas9 changes in DNA strands that is mutation . They cut DNA strands at specific location in genome from that DNA can be added or removed.

CRISPR :- CLUSTERED REGULARLY INTERSPACED SHORT PALINDROMIC REPEATS.

There were controversy related to it :- that was Gene Edited BABIES and CRISPR Cas9 . That was news from china that chinese scientists He jiakuo , he firstly claimed that he have used gene editing technology called CRISPR Cas9 to create Embroys. After that he transferred that into a women and and as a result she will gave twin girl .
