Drosophila may be monosomic for chromosome 4, yet remain fertile. A recessive mutant for bent bristles is identified on chromoso
nordsb [41]
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>

Analysis of pedigrees using knowledge of Mendelian principles allows us to; Determine whether the trait has a dominant or recess
Mashutka [201]

Answer:

Determine whether the trait has a dominant or recessive pattern of inheritance

Explanation:

This kind of information can be used to predict inheritance patterns in families. Depending on the genotypes, the dominant and recessive alleles and the different crosses, it can be deduced who are carriers of the disease and who express it. Similarly, by letting us know which chromosome (X or Y) is linked to the disease, we can know if the disease will be transmitted to the next generation depending on the genotypes of the parents.

If an individual inherits one dominant allele and one recessive allele. what is the genotype?
Inessa05 [86]

Dominant Inheritance. When a trait is dominant, only one allele is required for the trait to be observed. A dominant allele will mask a recessive allele, if present. ... Offspring whose genotype is either AA or Aa will have the dominant trait expressed phenotypically, while aa individuals express the recessive trait.

tresset_1 [31]

Meiosis II is reduction  division which produces four nuclei in 4 haploid cells for a total of four nuclei.

Explanation:

Meiosis 2 is the second phase of meiosis in which each diploid cell gives 2 haploid cells forming four haploid cells. It takes place in eukaryotic cells in gametes or germ cells. Sister chromatids separate in meiosis 2.

It comprises following stages:

prophase II : nuclear membrane breaks down as chromosome condense. spindle fibres get formed and microtubules prepare to grip chromosome.

metaphase II : The chromosomes are lined at metaphase plate.

Anaphase II: the sisters chromatids gets pull apart.

telophase II : nuclear memebrane is formed around each pair of chromosomes, decondensation of chromosomes occur and cytokinesis follow making four haploid cells.
