The exchange of genetic material between non-sister chromatids that may result in new gene combinations on the chromosomes is called the random assortment. It involves formation of random combinations of chromosomes in meiosis and of genes on different pairs of homologous chromosomes by the passage according to the laws of probability of one of each diploid pair of homologous chromosomes into each gamete independently to each other pair.
Answer:
Explanation:
To calculate the recombination frequency, we have to know that 1% of recombinations = 1 map unit = 1cm. And that the maximum recombination frequency is always 50%.
The map unit is the distance between the pair of genes for which every 100 meiotic products, one of them results in a recombinant one.
So, en the exposed example:
- J and K are autosomal genes
- J and K are separated by 60 M.U.
- 60 M.U. means that there is 60% of recombination.
Cross) J K / j k x j k / j k
Gametes) JK Parental jk, jk, jk, jk
jk Parental
Jk Recombinant
jK Recombinant
One map unit equals 1% of recombination frequency. This means that every 100 meiotic products, one of them is a recombinant one.
1 M.U. -------------- 1% recombination
60 M.U. ------------ 60% recombination
30% Jk + 30% jK
100 M.U. - 60 M.U. = 40 M.U.
40M.U.--------------40 % Parental (Not recombinant)
20% JK + 20% jk
Punnet Square) JK jk Jk jK
jk JK/jk jk/jk Jk/jk jK/jk
J K / j k = 20%
j k / j k = 20%
J k / j k = 30%
j K / j k = 30%
Explanation:
Photosynthesis is a chemical pathway that’s integral to producing energy in plants and other primary producers. Energy stored within carbohydrates, like molecules of glucose is produced from light, water and carbon dioxide while oxygen is released.
6CO2 + 6H20 + (energy) → C6H12O6 + 6O2 Carbon dioxide + water + energy
Carbohydrates molecules that supply energy and provide support; they consist of mainly sugars or starches in long chains and rings to form monosaccharide monomers. Inclusive of monosaccharides, disaccharides and polysaccharides (which describes the type of bonding and the degree of complexity of the polymers), their basic makeup comprises C, H, O -with many polar OH groups.
The energy they store, is required by all living organisms for biological processes; these undergo respiration, in order to release energy stored within its bonds, in the form of the molecule ATP.

Answer: Condensation
Water vapor is water in a gaseous state. Transformation of water into gaseous state
(water vapor) is called evaporation. Transformation of the water vapor into dew
which Michael observed in the early morning is called condensation.
Dew<span> is water droplets
that appears on exposed objects like
leaves in the morning or evening due to condensation</span>
Yeast means <span>microscopic fungus consisting of single oval cells that reproduce by budding, and are capable of converting sugar into alcohol and carbon dioxide.
mold is where we get medicine from.
mildew is </span>a thin whitish coating consisting of minute fungal hyphae, growing on plants or damp organic material such as paper or leather.
mushrooms increase spread and develop rapidly.
i hope this helps u.
