Answer:

1. Probability is 50% or 1/2

2. a) Genotypic ratio= 1 AA: 2Aa : 1aa

b) Phenotypic ratio = 3 normal pigment : 1 albino

3. Monohybrid cross

Explanation:

This question involves a single gene coding for pigment in humans. The allele for normal pigmentation (A) is dominant over the allele for albinism (a).

According to this question, if two heterozygous parents (Aa) are crossed i.e. Aa × Aa. The following proportion of offsprings will be produced:

AA, Aa, Aa, and aa

- Hence, the probability of having a heterozygous offspring is 2/4 or 1/2 or 50%

- Genotypic ratio= 1 AA: 2Aa : 1aa

Phenotypic ratio = 3 normal pigment : 1 albino

c. This type of cross is called MONOHYBRID CROSS because it involves a single gene

A woman who has sickle cell anemia passes this disease on to her offspring. This means that the mutation for sickle cell anemia

WITCHER [35]

The mutation will occur on the X chromosome. Males are more susceptible to sickle cell amenia because they only carry one X chromosome instead of two when compared to a set of female chromosomes. If a female only has the mutation on one chromosome the disease will not appear. However, when a male recieves the mutation on the X chromosome, the disease would appear, because they only have one X chromosome.

Cells undergo differentiation during embryonic development. An individual skin cell develops differently from a muscle cell beca

Anni [7]

An individual skin cell develops differently from a muscle cell because the cells express different genes.
All the given cells present in the body, be it skin or muscle cells have the same DNA and the same set of genes. However, these cells are able to develop differently from each other due to the differential expression of their genes.
Differential expression of genes means that the different cells which perform different function although have the same set of genes, express different genes at different times and thus, look and function differently.
Skin and muscles cells also express a different set of genes and thus they develop differently from each other.
