An animal has the genotype Cc for a particular trait. If, through meiosis, a certain female produces 100 eggs, how many of these eggs would have the C gene?
To determine how many eggs would have the C gene, we need to understand how alleles are inherited through meiosis. Meiosis is the process of cell division that leads to the production of gametes (eggs or sperm) with half the number of chromosomes as the parent cell.
In this case, the animal has the genotype Cc, which means it has one copy of the dominant allele (C) and one copy of the recessive allele (c) for the trait. During meiosis, the chromosomes segregate, and each gamete receives only one allele for each trait.
Since the animal has the genotype Cc, it can produce two types of gametes: one with the C allele and one with the c allele. These gametes are produced in equal proportions because the C and c alleles segregate randomly during meiosis.
So, out of the 100 eggs produced by the female, approximately 50 of them would have the C gene (C allele), and the other 50 would have the c gene (c allele).
