Answer:
1. 50% of the genome comes from each parent because it is crucial otherwise if the ratio changes, the zygote may not form and if formed the fetus may have some other kind of chromosome number related syndromes etc.
2. Sexual reproduction produces greater genetic variability than asexual methods. This is because of the process of crossing over during meiosis that exchange the segments of chromosome that is necessary for producing mutations and genetic variability.
3. 50% of chromosomes match with each parent because both of the parents contributed 23 chromosomes and exactly 50% of their genome.
4. The gametes must be produced by two different individuals cause that is the main purpose of sexual reproduction and give better survival like this to the forming next generation. Not to mention produces greater genetic variability among species.
5. Plants always produces both eggs because they are hermaphroditic in nature.
Answer:
Fungi is a unique living organism and it is not considered plant or animal and forms its own kingdom Fungus. On of the most unique features of a Fungi is that its body is composed of thread like structure called Hyphae and produce fruiting bodies, in which spores are formed are help the fungus in reproduction.
Coming towards the question that what is the unique feature of the structure of Hyphae and fruiting body that helps them in their function.
1: Hyphae:
Hyphae are composed of thread like structures called Hypha that are filamentous in nature. Due to its filamentous nature, it helps the fungi to better absorb nutrients from soil and anchor the fungus well in soil.
2: Fruiting body:
The fruiting body is main organ of fungi concerned with reproduction. It has rounded cap like structure in which spores are formed and are disseminated from one place to another and help fungi in reproduction.
Hope it helps!

MRNA is read 5->3
Start codons can vary depending on the cell/organism type although more generally for mRNA it is always: AUG which is always Methionine
Stop codons for mRNA are:
<span>UAG ("amber") , UAA ("ochre"), <span>UGA ("opal")
</span></span>
