LATE SUBMISSION RECORD: It is important that all deadlines for assignments are adhered to. Any candidate
needing an extension must have this agreed with the tutor in advance, with full reasons recorded. If this
cannot be done in advance, work handed in late must be accompanied with satisfactory evidence for the late
submission (e.g. medical certificate.)
Failure to follow these instructions will result in a maximum of PASS for graded units.

This unit has 3 learning outcomes.
LEARNING OUTCOMES ASSESSMENT CRITERIA
The learner will:
The learner can:
1. Understand the human reproductive
system.
1.1. Describe the structure and function of
the male and female reproductive
systems, including gamete formation.
1.2. Explain fertilization.
1.3. Describe human em
yonic and foetal
development.
1.4. Describe the birthing process.
1.5. Outline the menstrual cycle.
2. Understand meiosis and Mendelian
genetics.
2.1. State Mendel’s laws.
2.2. Describe chromosome behaviour in the
meiotic divisions.
2.3. Predict outcomes of genetic crosses
with Punnett squares for dominant-
ecessive, co-dominant, sex-linked and
multi-allelic inheritance patterns.
3. Understand human inherited conditions XXXXXXXXXXIdentify classes of genetic mutations in
humans.
3.2. Explain how an allele associated with a
human genetic condition might confer a
selective advantage.
3.3. Interpret human karyotypes in terms of
the sex of the individual and any
abnormalities in the chromosome pairs.

Task 4. (A.C 2.3)
Complete the following genetic crosses.
a) Tay-Sachs is an autosomal recessive disorder with the following alleles:
T – Unaffected allele
t - Affected allele
Complete a punnet square for a monohy
id cross, where both parents are heterozygous. (include phenotype
and genotype ratios).
) Blood type is a co-dominant multi-allelic trait with the following alleles:
A – Co-dominant
B – Co-dominant
o – Recessive.
Complete a punnet square for a monohy
id cross, where 1 parent is heterozygous blood type A and the other
parent is heterozygous blood type B. (include phenotype and genotype ratios).
c) Haemophilia is an X-linked disorder with the following alleles:
X’ Affected
X Unaffected
Y Unaffected
Complete a punnet square for a monohy
id cross, where the father is unaffected and the mother is a ca
ier
(include phenotype and genotype ratios).

LO 3. Understand human inherited conditions.
Task 5. (A.C 3.1, 3.2)
Sickle cell anaemia in a genetically inherited recessive disorder. Explain the type of mutation that has led to
the sickle cell trait and how this disease may have a selective advantage.
