For a dominant/recessive trait, do the offspring of identical parents always look like the parents?

Biology
1 answer:
Mashcka [7]2 years ago
5 0

Answer:

No, they don't always look like the parents.

Explanation:

They won't always look like the parents because from each parent, they will receive different dominant and recessive traits. In addition, certain traits skip generations or don't get passed down. For example, you can have 2 parents with red hair and have dark brown hair, but have a child who DOES have red hair.

Egg and sperm cells (or their precursors) are called germ cells. all other cells in the body are called?
Vinvika [58]

All other cells in the body are called Somatic cells.

What are germ cells?

The founding cells of all sexually reproducing organisms are known as germ cells. They are separated from the embryo's other somatic cells during development. Germ cells grow at the edge of the embryo proper in many animals before moving through a number of developing somatic tissues on their way to the developing gonad.

What are somatic cells ?

Any cell in the body that is not a gamete (egg or sperm), a germ cell (cell that develops into a gamete), or a stem cell is referred to as a somatic cell. Somatic cells are essentially any cells that make up an organism's body and are not directly utilised to create a new creature during reproduction.

What is the role of a fungus’s fruiting body?
jek_recluse [69]
The answer is a production of spores which are used for reproduction. 

In fungi, the fruiting body contains spores, which are the fungi's reproduction units. Spores are released by wind, rain, or animals. Once they land on an adequate surface they grow into hyphae, and eventually form a mycelium. The mycelium can later develop into the fruiting body and, thus, the cycle is repeated.

Cystic fibrosis is a recessive genetic disorder caused by a mutation of the CTRF gene. The disease is characterized by excessive
tekilochka [14]

Answer:

Since both Anthony and Sara are healthy carriers of the gene that causes cystic fibrosis, the chance of having a child with this disease are 1:4 (option D).

Explanation:

The inheritance pattern of cystic fibrosis is autosomal recessive, and considering that both parents carry the abnormal CFTR gene, it can be said that the parental genotypes are:

<em>Anthony N/Qf </em>

<em>Sara N/Qf </em>

Where N is the normal gene and Qf is the abnormal gene.

Since this is an autosomal recessive disorder, only the homozygosity of the defective allele will cause the disease to manifest :

N/Qf X N/Qf

<em>Alleles     N       Qf </em>

<em>N            N/N    N/Qf </em>

<em>Qf           N/Qf  Qf/Qf </em>

  • The chances of having a healthy child are 25%.
  • The chances of having a carrier child are 50%.
  • The chances of having a child with cystic fibrosis are 25%.

Therefore, the chance of Anthony and Sara having a child with cystic fibrosis is 1:4.
