I just got it right
Answer:
In order for scientists to keep track of endangered species and discover new species that are created due to the constant change.
Answer:
The correct answer will be option-A
Explanation:
Desert biomes are characterised by the presence of the arid conditions or with few or less amount of rainfall.
The plant groups called the bryophytes and pteridophytes are dependent on the water for their fertilization which allows completing their life cycle.
In the desert conditions provided in the question, the mosses and ferns survived for many generations as these plant groups produced sperms with flagella which helped the sperms to swim in the water provided by the 10-inch rainfall per year and reach the female gamete and fertilize the egg cell.
Thus, option-A is the correct answer.
Answer:
Gl, gL, GL and gl
Explanation:
The heterozygous parent has the genotype Gl/gL. Since this is a diploid individual, it has two copies of each autosomal chromosome. The slash "/" represents a separation between the two homologous chromosomes, <em>Gl</em> are the alleles of genes "G" and "L" present in one chromosome, and <em>gL</em> are the alleles of those genes present in the other chromosome.
During meiosis the total chromosome number of the original diploid cell is reduced by half, creating four haploid gametes. In a specific stage of meiosis, homologous chromosomes pair and crossing over occurs, when recombination happens and one of the alleles present in one chromosome "switches" to the other chromosome, increasing genetic variation.
<u>Therefore, the Gl/gL individual can produce four different types of gametes:</u>
Gl and gL (Parental --> no crossing over occurred)
GL and gl (Recombinant --> crossing over occurred)
