Genetics Answers

If parents were heterozygous X,Y. what blood groups of offsprings we observe

can Mendelian explain about all inheritance of genetic diseases in humans? are any exceptions?

pP×PP are parents, predict the phenotype and genotype of F1 and F2 after the test cross

Assess the possibility of errors occurring during the stages of protein synthesis, particularly during transcription and translation. Analyse the cause and effect of genetic mutations in DNA, including:

• Missense 

• Nonsense

• Silent

• Insertion

• Deletion

• Duplication

• frameshift

Provide examples of the impact that these errors may have on the end products of protein synthesis

List the characteristics of dominant inheritance linked to the X chromosome.

Give 2 examples of diseases.

Describe the scheme when crossing

2) a healthy woman and a sick man

Provide examples of the impact that these errors may have on the end products of protein synthesis.

Discuss how the genetic code allows proteins to be synthesised with minimal errors taking place, including:

• triplet codes

• codon

• anticodon

• degenerate code

• non-overlapping

• DNA – stages and enzymes involved in DNA replication

• RNA – mRNA, tRNA, rRNA, siRNA
