Biology
1 answer:
shusha [124]3 years ago
4 0

Answer:

I would say one or more cells.

Explanation:

Unicellular organisms like bacteria contain one cell.

A multicellular organism, like us humans, contain many cells.

Therefore, all other options can be ruled out as living things can have one cell, or many cells.

Given the information below, answer the following questions, assuming complete dominance. Tongue rolling is a dominant trait. If
adelina 88 [10]

Answer:

The chance that their <u>child will not be able to roll his tongue will be zero</u>.

The chances to have a child with tongue rolling ability is 100%.

Explanation:

In complete dominance, a dominant gene completely manifests over a recessive gene. If tongue rolling is a dominant trait, this means that the gene that expresses this trait is dominant over the recessive one that does not allow the person to roll the tongue.  

If the gene for tongue rolling is called T, then a person that is homozygous dominant for this trait will have the following genotype: TT. If the person is heterozygous for this trait, the genotype will be Tt. And if a person is homozygous recessive for the trait, this person´s genotype will be tt.

When two homozygous dominant individuals mate, their chances to have a child with tongue rolling ability is 100%.

This is:    

Parental)         TT   x   TT

Gametes)     T   T       T   T

Punnet Square)                  T                 T

                                T        TT             TT

                                T        TT             TT

F1)  Genotype: 100% TT, or 4/4 TT

      Phenotype: 100% Tongue rolling capable.

A child is born to parents that both have hypophosphatemic rickets, a disease that is caused by a sex-linked dominant trait. Wha
Sati [7]

Answer:

75%

Explanation:

Hypophosphatemic rickets is a disorder characterized by hypophosphatemia (low level of phosphate in the blood), defective intestinal absorption of calcium, and rickets (impaired mineralization of cartilaginous growth plates)  or osteomalacia (impaired mineralization of the osteoid) unresponsive to vitamin D. It can be inherited or acquired.

When it comes to inheritable hypophosphatemic rickets, the disorder is most often inherited in an X-linked dominant manner. This means that the gene is inherited through the X chromosome and that one dominant allele is enough to cause it.

As the mother is heterozygous for the trait, she has one dominant and one recessive allele (XHXh). The father has one X chromosome, which he inherited from his mother, and as he has the condition, the dominant allele will be present on it (XHY).

This means that, if the child is a girl, she will definitely have the disorder. Girls inherit one X chromosome from each of their parents. Even if she inherited the one with the recessive allele from her mother, she would get the one with the dominant allele from her father.

If the child is a boy, he has a 50% chance to inherit the condition. Boys inherit the Y chromosome from their father and the X chromosome from their mother. As the mother is heterozygous, he can either get the chromosome without the dominant allele or the one with it. This means that there is a 50% chance of inheriting the disorder.

If we say that there are equal chances of this couple having female and male children, when we combine these results, we get a 75% chance of them inheriting hypophosphatemic rickets.
