What make the si system better than the english system of measurement?

The SI system or metric system is the most commonly used system of measurement around and hence makes it more applicable around the world than the english SOM

Both systems are used to numerically describe measurement. The SI system is based on the number 10 as well as multiples and products of 10. This makes it much easier to use, and so it has been the accepted system in scientific and technical applications. The English system is more complicated as relationships between units of the same quantity aren’t uniform.

Alleles for the same trait are separated from each

Oksana_A [137]

Answer:

B. Meiosis I

Explanation:

In meiosis I, it starts with a diploid cell with a homologous chromosome pair. The crossing of genetic material between chromosome pairs also occurs in this stage. The alleles containing the same trait would get separated so a new combination of alleles can be produced.

the couple is also concerned about their child inheriting hemophilia, another rare disease, which is x-linked. natalie’s brother

IgorC [24]

Hemophilia is a recessive X-linked condition and is inherited from parents. . The probability that Natalie and Daniel’s first child has hemophilia is 1/4, not 1/8. The statement is false.

<h3>What is an X-linked gene?</h3>

When talking about sex-linked genes, we refer to all those genes located in one of the sex-chromosomes and not in the somatic ones.

X-linked genes are the genes located specifically in the X sex chromosome.

Traits coded by these genes are inherited. This is, X-linked genes are transmitted from parents to children through generations.

According to this, X-linked genetic disorders will be inherited as well.

Men have a high probability of being affected since they only have one copy of the X chromosome.

In women, the effect of the mutation might be musk in heterozygous state if the mutation is recessive.

Hemophilia is a recessive X-linked disorder, which means it is coded by the recessive allele.

X+ ⇒ X chrosomosome with Dominant allele

X- ⇒ X chrosomosome with Recessive allele

Genotype Phenotype

X+X+ Healthy woman

X+X- Healthy carrier woman

X-X- Hemophilic woman

X+Y Healthy man

X-Y Hemophilic man

Let us make a pedigree of these families,

Natalie's family:

Mother healthy carrier X+X-

Father healthy X+Y

Brother hemophilic X-Y

Natalie Healthy X+X- or X+X+

Natalie has 1/2 chances of being carrier X+X- and 1/2 of being X+X+.

Daniel's family:

Mother healthy carrier X+X-

Father hemophilic X-Y

Sister hemophilic X-X-

Daniel Healthy X+Y

He has 1/2 chances of being healthy X+Y and 1/2 of being affected X-Y.

According to the product probability rule, if events A and B are independent from each other, the probability of occurrence of both events together is

P(A∩B) = P(A) x P(B)

In this case,

event A is Daniel being affected ⇒ 1/2
event B is Natalie being carrier ⇒ 1/2

P(A∩B) = P(A) x P(B) = 1/2 x 1/2 = 1/4

The probability that Natalie and Daniel’s first child has hemophilia is 1/4, not 1/8. The statement is false.

The round pea seed trait is dominant over the wrinkled pea seed trait. If the phenotype of a pea seed is wrinkled, which combina

vovikov84 [41]

The wrinkled pea will have two recessive alleles on the locus.

Explanation:

Two forms of same gene are called alleles of that gene.

The allele that expresses itself under heterozygous condition is called the Dominant allele.

The recessive allele can express itself only if they are under homozygous combination i.e. both the alleles on homologous chromosome are recessive.

Here wrinkled pea is a recessive trait and if it is expressed in the phenotype then the genotype of the plant must be homozygous for the recessive allele.
