Answer:
Two other possible genotypes are: SS and ss.
Explanation:
MOTHER ALLELES: S s
FATHER ALLELES: S s
Offspring genotype:
SS Ss Ss ss
Then, a quarter of the descendants will be homozygous for the recesive allele (ss) and an other quarter, homozygous for the dominant allele (SS)
It can replace, repair or be a new type of cell to benefit the host.
Cellular differentiation occurs throughout the cell development of a multi-cellular organism. It occurs when the cell changes from a simply zygote into a complex system of tissues and cell types.
<span>Stems cells are cells which have the potential to develop into many different cell types in the body during early life and growth. Stem cells serve as internal repair system in many tissues. When stem cells divide while undergoing cell differentiation, it can either retain being a stem cell or become another type of cell like muscle cell, brain cell, or red blood cell.<span> </span></span>
Answer:
If the disorder has an autosomal recessive inheritance pattern, according to the family tree both parents do not have the disorder, but are carriers.
Explanation:
When a disorder or disease is recessive it requires<u> two alleles with the disorder to manifest</u>. In this case, according to the pedigree, both parents must be heterozygous carriers and not present the disorder.
<u>Parents
</u>
♂ Dd
♀ Dd
Both without disorder but presenting the altered gene, which makes them carriers.
<em>Alleles D d
</em>
<em>D DD Dd
</em>
<em>d Dd dd</em>
The offspring of these parents have a 50% chance of being carriers without the disorder, 25% non-carriers, and 25% with the disorder.
In the event that either parent was DD, there would be a 50% chance of carriers without the disorder and no chance of offspring with the disorder, which has a recessive inheritance pattern.

No
