Explanation:
Answer:
A) releasing carbon dioxide into the air
Answer:
E. will have the same genes at the same locations
Explanation:
Homologous chromosomes are the pairs of chromosomes. The members of a homologous pair are genetically and morphologically similar to each other. One chromosome of a homologous pair is inherited from the father while the other one comes from the mother.
Genes have two or more alleles. The alleles of a gene occupy the corresponding position on the homologous chromosomes. These specific positions of alleles of a gene are called loci. Therefore, a particular locus is occupied by alleles of the same gene on two homologous chromosomes.
The answers are:
<span>a. -/b+
</span><span>d. b/b+</span>
b+ - the allele for normal bristles
b - the allele for bent pristles
Monosomic means there is only one instead of two alleles in a gene locus.
So, the parents' genotypes are:
<span>monosomic bent bristles: -/b
</span><span>diploid normal bristles: b+/b+
</span><span>The following cross is conducted of true-breeding adult flies:
Parents' phenotype: monosomic bent bristles x diploid normal bristles
Parents' genotype: -/b x b+/b+
F1 generation: -/b+ -/b+ b/b+ b/b+</span>
