Genetics Answers

Indicate clearly where the opportunities arise in meiosis for genetic variation and outline and illustrate briefly how this happens.

a) Outline Mendel's first law.

b) Briefly explain the terms,

• monohybrid inheritance

• dominant and recessive

• genotype and phenotype

• homozygous and heterozygous

Use specific examples with genetic notation to illustrate your answer and show links between the terms

1. Explain the terms Chromosome, Chromatid, Gene, Allele.

(Use genetic notation (symbols for alleles) and annotated diagrams to illustrate your response. Show links between the terms)

2. Identify the mixed up stages of meiosis, shown in appendix A. Write a breif sentence to justify the stage identified. Complete this all within the appendix table and place within your assignment.

Indicate clearly where the opportunities arise in meiosis for genetic variation and outline and illustrate briefly how this happens.

As a result of working out, you are able to jump higher and run faster. In biology, this is an example of

A local hospital has informed a family that some of the children may have been mixed up with children from other families when they were born. The hospital obtained the blood types of everyone in the family, including the surviving maternal grandfather and paternal grandmother, to rule out any possible mix-ups. The following were the outcomes:

Father: Type O Mother: Type A

1st child: Type O 2nd child: Type A

3rd child: Type B Mom's father: Type AB

Dad's mother: Type B

High blood pressure can have a genetic component. One possible genetic component of high blood pressure is a mutation in a single gene. If this gene is to be transferred to the offspring, should it be in a somatic cell or gametic cell?

if there is incomplete dominance or codominance of 2 alleles how many phenotypes will be seen ina population

Suppose that your arm, hand and foot was made up of only one cell. What would happen if the cell stopped working or died?

A researcher studying genetic influences on learning compares the maze performance of four genetically different strains of mice, using eight mice per strain. Performance for the four strains were as follows:

A man with AB blood marries a woman with a heterozygous type B blood. What percentage of their children will have Type A blood?
