Stem cells are immature cells that do not have a specific function. What causes these cells to become specialized cells such as
kvasek [131]

Stem cells become specialized cells such as blood cells because certain genes are activated and cause a particular cell to develop (Option B). It is called differentiation.

<h3>What is cellular differentiation?</h3>

Cellular differentiation refers to the process by which certain genes are expressed in a particular cell lineage.

Cellular differentiation leads to the formation of mature specialized cells that perform specific functions.

For example, immature hematopoietic stem cells become differentiated to produce mature red blood cells.

What are the most likely percentages for offspring of two red/white-feathers parents?
weeeeeb [17]

Answer:

The question lacks options, the options are:

parents?

A.100% red/white-feather chickens.

B.50% white-feather chickens and 50% red/white-feather chickens.

C.33% white-feather chickens, 33% red-feather chickens, and 33% red/white-feather chickens.

D.25% white-feather chickens, 25% red-feather chickens, and 50% red/white-feather chickens

The Correct answer is D

Explanation:

According to the question, the hybrid chicken has a mixture of red and white feather phenotypes expressed at the same time. This tells us that the red and white alleles are CODOMINANT in the chicken i.e. none is dominant or recessive over the other.

Let's assume that (R) allele is the red feather colour while (r) allele is for white feather colour. Therefore, the red/white feathered chicken will have a Rr genotype. In a cross between two red/white feathered chicken (Rr), the following offsprings will be produced RR, Rr, Rr and rr

RR- Homozygous red feather d chicken (1/4 × 100=25%)

Rr- Hybrid Red/White feathered chicken (2/4 × 100=50%)

rr- Homozygous white feathered chicken (1/4 × 100=25%)
