The sequence of the genes will be ABCD, abCD and abCd, abcD.
Full question is attatched below.
<h3><u>Explanation:</u></h3>
The genes in the chromosomes are denoted as the sequence of genes present in a single chromatid of a particular chromosome. Thus, the genes here in this question are to be mentioned as ABCD and not as abab.
Crossing over is the process by which the homologous pair of chromosomes do pair up in the Prophase 1 of meiosis 1 division and they exchange a particular part of their DNA with each other. This leads to exchange of genes between the homologous chromosomes, which will form different gametes in near future. This brings about a variation between the offsprings of same individuals.
Here the d gene of the two chromosomes are getting exchanged.
So the chromosomes will become ABCD, abCD and abCd, abcD respectively.

Hi dude
This means farming that not only produces food, jobs and economic well-being, but also creates cultural, social and environmental benefits. Agroecology also protects and provides ecosystem services like pollination, natural pest control, nutrient and water cycling and erosion control.
Agro ecology is the future of farming
Farming for the Future is a holistic farming approach that starts with building and maintaining the soil, because healthy soil is better able to retain water, reducing irrigation and water usage, and soil erosion and loss of top soil are reduced.
Agroecological methods can also help farmers cope with climate change by enhancing resilience. Agroecology has the explicit goal of strengthening the sustainability of all parts of the food system, from the seed and the soil, to the table, including ecological knowledge, economic viability, and social justice.

Answer:
Water is not required for the fertilization.
Explanation:
The plants can reproduce by the means of asexual reproduction and sexual reproduction. The pollen grains and egg cell fertilize with each other in the sexual reproduction.
The seedless vascular plants and non vascular plants required the means of dispersal for their fertilization. Their egg cell fuses with the pollen grains that are dispersed by animals or wind. Water is not required for the fertilization of the vascular plants.
