Answer:

Parental ditype (PD):

Parental ditype may be defined as the teterad type of the ascus that contains two different genotypes. These genotypes are both of the parental type. These are non recombinant ascospores.

Non-parental ditype (NPD):

Non-parental ditype may be defined as the ascus spores that do not resemble with the parent genotype. These tetrad type are the recombinant type of the ascus.

Tetratype:

Tetratype are the spores that contains the four different genotypes. The two genotypes are the parental type and two are recombinant type. The tetratype indicates the single cross overs.

BigorU [14]

Answer:

b

Explanation:

<em>Let the wild type trait, the silver-white, be represented by </em><em>A</em><em> allele and the mutant trait, the golden color, be represented by </em><em>a</em><em> allele.</em>

Heterozygous wild-type male fish would be Aa

Golden female fish would be aa

     Aa    x    aa

  Aa   Aa    aa    aa

2/4 Aa = silver-white

2/4 aa = golden color

<em>Hence, the percent likelihood of golden offspring is </em><em>2/4 or 50%.</em>

The correct option is b.

bixtya [17]

Answer:

Mechanical isolation

Explanation:

mechanical isolation is a form of prezygotic reproductive barrier, whereby similar species organisms become isolated and unable to successfully interbreed with each other to form zygote, as a result of incompatibility of their reproductive organ or structure, which prevents them from copulating. As a result of this, both species become separated as there is no gene flow between both.

The two species of juniper can be said to be kept separate by <em>mechanical isolation</em>, due to the differences and incompatibility of their reproductive structure.
