1. Meiosis : During prophase of meiosis I, crossing over occurs which results in intermixing of genes between parent.

2. 25 %. In monohybrid cross, offspring produced in phenotypic ratio 3:1. ( 4 offspring, each have 25 % )

3. 75 %. In monohybrid cross, offspring produced in phenotypic ratio 3:1. 3 (75 %) with dominant trait and 1 (25%) with recessive trait.

4. 100%. In incomplete dominance all the offspring produced in F1 generation is neither dominant nor recessive. in this case all offspring will be pink.

5. Tt. Both the alleles T and t will segregate independently.

6. aabb. it will be the rarest combination.

7. 56%. 9 out of 16 seeds produced in the ratio 9:3:3:1 will be round and yellow.

Answer: The most accepted guess is: By bamboo rafts.

Explanation:

There are two hypotheses.

The first is that they arrived on Flores as Homo erectus and then evolved to Homo floresiensis. The second is that they were already Homo floresiensis when they arrived. This second one is the more accepted hypothesis because it would take organization and language to accomplish this technological water transportation feat. Homo erectus is not known to have developed speech.

Now at the time this transport was estimated to have happened, 100000 years ago, the islands of Komodo and Flores were joined and visible from the mainland. Together they constituted a 19km wide straight visible that could be easily seen from the mainland. The Homo floresiensis tribes built bamboo rafts, or possibly some other floating apparatus made if wood, and sailed there. The islands then progressively drifted apart, isolating them.

PS: It is important to note that some things may have drove them there such as famine, violence, etc.

Which of Mendel's laws or principles states that gametes carry one allele for each trait?
Burka [1]
Law of segregation states that <span>gametes carry one allele for each trait
As it states that
</span>that during the production of gametes the two copies of each hereditary factor segregate<span> during the production of gametes</span>  so that offspring acquire one of the two allele  from each parent
so option C is correct
hope it helps
