Genotype- B= Brown and T= Tan
Genotype- BB because if the mouses mate they will give their dominant gene and they both share the same gene so their baby will have to have the same gene.
Phenotype- Brown Mouse

Answer:
It is D because when the locusts came the next year, the sparrows did not eat the locusts.
Explanation:
Answer:
D. the genetic material of living organisms
Explanation:
Answer:
All of the answer options are correct.
Explanation:
Chargaff contributed in understanding the structure and composition of DNA with his discoveries. He discovered that purine and pyrimidine bases are in equal amounts in a DNA molecule. He also discovered that amount of Adenine base (A) is equal to amount of Thymine base (T). It means that A pairs with T. Since A is a purine and T is a pyrimidine it also implies that purine base pairs with a pyrimidine base. This conclusion can also be arrived by taking in consideration the other base pair which is G (purine) and C (pyrimidine).
Random orientation of homologous pairs of chromosomes during meiosis I results in alternative arrangements that contribute to genetic variation in offspring. This is called "independent assortment".
<u>Explanation:</u>
The sets of homologous chromosomes, also recognized as bivalents or tetrads, align along the metaphase plate in a random order in metaphase I of meiosis I. Another way for cells to incorporate genetic variation is by spontaneous orientation. Mendel's independent assortment law stipulates that, independently of one another, the alleles of two or more different genes are sorted into gamets.
In other terms, for one gene, the allele that a gamete receives does not affect the allele that is obtained for another.Genetic recombination (by random segregation) and crossing over during meiosis creates daughter cells each containing different combinations of maternally and paternally coded genes.
