Answer:
The cross of a heterozygous fly with a homozygous fly can be shown as follows:
r r
R Rr Rr
r rr rr
The results show that there is a 50% probability that the flies produced will have red eyes. Their genotypes will be heterozygous.
The results of the punnet square show that there will be a 50% probability that the offsprings will have brown eyes. Their genotype will be homozygous recessive.
A homozygous trait can be described as a trait which has same alleles for the gene which encodes the trait. Heterozygous means that both the alleles for the trait will be different.
Answer:
i think over irrigation is the answer
Synapsis, also called syndesis is the process
of pairing between homologous chromosomes during meiosis. The exchange portions
of their chromatids enables pairing of homologous chromosomes prior to their
segregation and chromosomal crossover. This takes place during prophase I of
meiosis and this process is perilous for accurate segregation of the
chromosomes.
Answer:
Wilting occurs due to excess removal of water from plant body.
Crop rotation.
Explanation:
The main use of blue green algae is that it has the ability of fixing atmospheric nitrogen for the plants. Oil is extracted from Neem leaves which is used as fungicide and pesticide for plants. Turmeric is used as healing of wounds for both plants and animals. It also prevent fungal and bacterial disease in plants. Plants will wilt if not watered because water is removed from the body of plants in order to cool down the inner temperature so due to removal of excess water from plant body it will dry and start wilting. Crop rotation is used in these cropping system. Crop rotation is a practice of growing more than one crop on the same piece of land in a year.
Long line fishing, drift nets, and trawling all produce an insignificant amount of by-catch is a false statement.
Explanation:
Bycatch fishing is "the incidental capture of non-target species” like sharks, dolphins, seabirds, marine turtles and other marine organisms while applying modern fishing gears like long line fishing, drift nets, or trawling.
Although, these inconspicuous modern fishing gears are highly efficient in catching the desired types of target fishes; these also catch significant amount of other marine species which travel along the line as a bycatch.
A huge number of exclusive marine fishes which are mostly under the endangered list and many juvenile fishes are caught as bycatch which are mostly thrown back dead overboard. Further these modern gears also endanger the marine structures like the coral reefs.
