Answer:
One pair of homologous chromosomes.
Explanation:
One chromosome in a tetrad is paternally inherited, while the other is maternally inherited. Each chromosome consists of two chromatids.
Answer:
These changes can be caused by environmental factors such as ultraviolet radiation from the sun, or can occur if an error is made as DNA copies itself during cell division. Acquired mutations in somatic cells (cells other than sperm and egg cells) cannot be passed to the next generation
Answer:
a) BB
b) bb
c) Bb
Explanation:
Co-dominance is a type of non-mendelian genetic inheritance in which two alleles of a gene are neither dominant nor recessive over one another, hence, they form an hybrid offspring that simultaneously exhibits the traits encoded by both alleles. This is the case of the scale color gene in a certain fish. The allele for blue scales (B) and allele for red scales are codominant. Hence, they produce an hybrid with a patchwork of both blue and red colours.
Therefore, a fish with blue scale color will possess an homozygous genotype of the blue allele: BB while a fish with a red scale color will possess an homozygous genotype of the red allele: bb. Since the patchwork fish is an hybrid or heterozygous, it will contain a combination of the blue and red alleles i.e. Bb.
Because both alleles (red and blue) are codominant, both traits encoded by both alleles will be expressed at the same time in the hybrid organism (patchwork fish).
