A woman received the genes aBcD from her mother and AbCd from her father. Which gene combinations could be present in her sex cells: ABCD, abcd, ABCDD, aBccD, ABcd, AaBb?

Respuesta :

The woman received genes aBcD from her mother and AbCd from her father. Let's analyze the possible gene combinations in her sex cells:

1. ABCD: This combination is not possible as she does not have the allele "A" from her father in the uppercase form.

2. abcd: This combination is possible as it represents the combination she received from both her mother and father.

3. ABCDD: This combination is not possible as it includes an extra "D" allele that she did not inherit from her mother.

4. aBccD: This combination is not possible as it includes a "C" allele that she did not inherit from her mother in the lowercase form.

5. ABcd: This combination is possible as it represents the combination she received from both her mother and father.

6. AaBb: This combination is not possible as it includes lowercase alleles "a" and "b" that she did not inherit from her father.

Therefore, the possible gene combinations in her sex cells are abcd and ABcd.
