A daughter has hemophilia, a recessive sex-linked trait. Which are possible genotypes of her parents?

Biology
1 answer:
marusya05 [52]3 years ago
5 0

Answer:

D. XHxh and XHY

Explanation:

since this is the only answer with genes that share a common allele, the answer is D.

In order for a recessive gene to be present, the daughter must have gained the alleles of XHXH, which in this case, is a 25% chance. The other two possibilites are XHxh, XHY, and Yxh. To further prove this, a female must have 2 X alleles and to have hemophilia, they must carry 2 H's. If they were to only have one H, they would be a carrier instead of a product.

Bacteria undergo mitosis and meiosis in order to reproduce and increase genetic recombination.
Salsk061 [2.6K]

Answer:

The correct answer is (b)-False

Explanation:

Bacteria do not undergo meiosis or mitosis to reproduce and increase its genetic recombination. To increase their genetic recombination bacteria take the help of horizontal gene transfer through which it gets the genetic material of another bacteria. This new gene helps bacteria to survive in the challenging environment.

Bacteria divide through binary fission in which one cell of bacteria divides into two equal daughter cell each having its genetic material because genetic material of parent cell segregate equally into both the cell.  

Therefore bacteria do not undergo meiosis or mitosis.
