Answer:
B. Multiple allele means more than two forms of the same gene in the population and polygenic inheritance means more than one gene contributes to the phenotype of a trait.
Explanation:
- Multiple alleles are an alternative form of allies and can occupy the same gene ad only two of them can be found in the same organism. Such as the ABO blood group.
- A polygenic or a multiple gene inheritance is a hypothetical gene that s often difficult to characterize and traits control a multiple of genetic loci, they are relatively small and interchangeable.
Answer;
D. Meiosis ii of mother
Explanation;
-The non-disjunction occurs in the meiosis II of the mother. This non-disjunction occurs when the two sister chromatids X and X fails to separate during meiosis II and produces an egg having two X chromosomes.
-Klinefelter syndrome is a condition that occurs in males when they have an extra X chromosome. The syndrome is not inherited, but usually occurs as a random event during the formation of reproductive cells (eggs and sperm) that results in the presence of one extra copy of the X chromosome in each cell (47,XXY).
Answer:
23 Chromsomes
Explanation
Thus, if a skin cell or somatic cell contains 46 chromosomes then the egg or sperm (gametes) would contain only 23 chromosomes
The answer is would b a true
