The answer is Both features have a recessive phenotype in these offspring.

An individual's phenotype is defined by their genotype and expressed genes, as well as apparent traits such as hair colour or type, eye colour, body shape, and height. It is determined by the genotype, but it is also modified by environmental circumstances.

What is genotype?

  • The genotype of a person can reveal their genetic makeup.
  • It determines which qualities will be expressed.
  • Organisms with similar appearances do not share the same genotype.
  • Biological tests can be used to determine a person's genotype.

14. Explain why women, and not men, can be carriers for the disease hemophilia. Why do the sons of
miv72 [106K]

Answer: Women are carriers for the disease hemophilia because hemophilia is an X-linked disease. The recessive allele for the disease is found on the X chromosome.

The sons of carrier women get hemophilia because males have one X chromosome and one Y chromosome. The sons of a carrier woman may inherit the affected X chromosome from their mother, and a Y chromosome from their father. They have only one X chromosome and one it's affected, will result in hemophilia.

Explanation: Women are carriers because in most cases, only one of their two X chromosomes are affected. The two female X chromosome is rarely affected.

Daughters of carrier women will not get the disease because they need two affected X chromosomes to manifest the disease. So even if they inherit one affected X chromosome from their mother, the second X chromosome they will inherit from their father will be normal. Therefore, daughters of carrier women can only be carriers.

A pathologist looks at the tissue under a microscope and runs other tests to see if the tissue is cancer. Some treatments for cancer include Chemotherapy, surgery, Radiation therapy, and bone marrow transplant.

The most common cause of arthritis is usually if your family has a history of arhritis. It is usually diagnosed with an x-ray or a blood test. Treatment includes Painkillers, physical therapy, and exercise.

The chromosomal mutation in the zygote can be traced back to which of the following? (4.3, 4.4)Immersive Reader
lawyer [7]

The chromosomal mutation in the zygote can be traced back to "Chromosome 6 in the egg cell".

<u>Option: B</u>

<u>Explanation:</u>

In germ cells i.e. egg or sperm cells, the mutations in chromosome often happen during the meiosis phase. The number of chromosomes in egg cells or sperm cells must be haploid, so that diploid chromosomes form zygote on fertilization. Chromosome mutation in meiosis leads in an additional set of chromosomes or structural defects in the chromosome.

Chromosomal mutations are often caused by chemical agents or by mutagens. The homologous chromosomes are segregated from sister chromatids throughout cell division, any abnormality at this point allows the chromosomes to be unequally divided or not disjuncted, same is observed in the situation seen in egg cell chromosome 6.
