I really hope this helps! I tried. And for the last one I’m not sure about it.

<u>Answer:</u>
<em>If Mendel crossed a true breeding dominant plant with a true breeding recessive plant the recessive trait is visible in the F3 generation.
</em>
<u>Explanation:</u>
In <em>Mendel’s cross the selected parents are a tall pea plant and a short pea plant.</em> Tall is the dominant trait and short is the recessive trait. Both the parents are homozygous.
Letter T represents tall and t represents short. Hence the phenotype TT is homozygous dominant and tt is homozygous recessive.
<em>The genotype Tt represents tall since T is dominant over t. Mendel’s cross can be represented as </em>
<em></em>
<em></em>
<em>F1 generation Tt Tt Tt Tt
</em>
<em>F2 generation TT Tt Tt tt
</em>
Answer:
Mitochondrial DNA is inherited from the maternal side
Explanation:
Mitochondrial DNA is inherited from the maternal side (from the oocyte). The mitochondria from the sperm cell including their DNA are degrade after fertilisation.
The size of the cells that make the zygote also contribute to this. The oocyte is much larger than the sperm, containing around 100,000 mitochondria, whereas the much smaller sperm cell only contains around 100. This means even initially, there are very few paternal mitochondria compared to maternal mitochondria in the first place, effectively diluting them out.
This, coupled with the degradation of the sperm mitochondria, means that offspring will not inherit mitochondrial DNA and any mutations from their father.
