Attached earlobes are recessive to free earlobes. If two heterozygous individuals have a child, what is the probability of the c

Sunny_sXe [5.5K]

Answer:

probability of the child having attached earlobes since it is recessive i.e (yy)

=1/4

=0.25 × 100%

=25%

Explanation:

If two heterozygous individuals have a child

i.e let the heterozygous individuals be = Xy

if both traits crosses together; their F₁ offspring will be; (XX, Xy, Xy, yy)

Xy × Xy

X y

X XX Xy

y Xy yy

probability of the child having attached earlobes since it is recessive i.e (yy)

=1/4

=0.25 × 100%

=25%

it important to know a person's rhesus factor before a blood transfusion? A patient who is Rh+ can receive only Rh– blood. A pat

The right answer is A patient who is Rh– can receive only Rh– blood.

The blood group is not the only thing that matters, it adds a category: rhesus. Rhesus refers to a red blood cell antigen that is on their wall. There are two blood group systems: Rh positive (Rh +) and Rh negative (Rh-).

Rhesus is positive in people who have this antigen. It concerns the majority of the population. Negative rhesus refers to people without the antigen. This rhesus factor is especially useful to know if a blood transfusion is feasible between two people.

The blood transfusions can be "iso-rhesus", that is to say between Rh + and Rh- but only in one sense: Rh- can give to Rh + but Rh + can not give to Rh-. Again because of the presence of antibodies directed against the antigen in Rh- people.

<h2>The Red-Cockaded Woodpeckers</h2>

Explanation:

Red-cockaded woodpeckers are sharp, socially adroit, and adorable.
They assemble settles by unearthing pits in old pine trees in the Southeast, which was an incredible transformative system until individuals cleaved down 97 percent of their natural surroundings.
<em> Snakes are a portion of their most risky home predators</em>, so the <em>winged animals peck the pine trees' bark </em>to make sap overflow down the tree trunk. The smooth of sap stops winds and protects the nest cavities above.
Each pine tree in a backwoods into timber or turpentine, it sets aside a long effort for trees to become large enough to help respectable size home depressions.
The <em>tree timberlands these flying creatures</em> advanced in was intermittently gotten out by fire, which is currently typically stifled, prompting woods that are unreasonably thick ridiculous.
