Explanation:
Firstly, look at the oldest female shape. It would be a circle since that is female and which circle, would be the oldest one. In line one. Since the circle is white, the gene has not been carried so it must be reccessive.
tt because it is the only allele pair that would give you the gene without obtaining that trait, meaning it is reccessive.
So it would make sense that tt is the choice.
Explanation:
In addition, in meiosis I, the chromosomal number is reduced from diploid (2n) to haploid (n) during this process. ... In humans (2n = 46), who have 23 pairs of chromosomes, the number of chromosomes is reduced by half at the end of meiosis I (n = 23).
Answer:
All these choices are correct
Explanation:
YACs stands for Yeast artificial chromosomes. These chromosomes are derived from a fungus species Saccharomyces cerevisiae. YACs are genetically modified and a 100—1000 kb fragments of DNA are inserted into a bacterial plasmid. The inserted DNA fragment can be cloned and physically mapped. In the presence of this fragment, the chromosome will be stable during extracellular replication and easily can be differentiated from colonies without the vector.
