Describe how genetic information is passed on from parent to a child
jarptica [38.1K]

Answer:

Chromosomes are passed from parents to offspring via sperm and eggs. The specific kind of chromosome that contains a gene determines how that gene is inherited. ... Consequently, each person has two copies (alleles) of every gene carried on an autosome: one inherited from their father and one from their mother.

Like chromosomes, genes also come in pairs. Each of your parents has two copies of each of their genes, and each parent passes along just one copy to make up the genes you have. Genes that are passed on to you determine many of your traits, such as your hair color and skin color

DNA sometimes has chemical groups attached, called methyl groups, that affect gene expression. Suppose that, during each hour, f
ira [324]

Answer:

f = m - u

Explanation:

DNA methylation is an important epigenetic modification associated with the regulation of gene expression. As such, the analysis of DNA methylation marks and the dynamics of this process may shed light on the genes that are being expressed at a given time in a given cell type/tissue. In the example above described, f is defined as the fraction of the DNA molecule that is methylated after one (1) hour, whose value can be estimated by subtracting u fraction (i.e., fraction of methylated locations that become unmethylated) from m fraction (i.e., fraction of unmethylated locations that become methylated).

In consequence, the equation is

f = m - u

A man has extra digits (six fingers on each hand and six toes on each foot). His wife and their daughter have the normal number
alukav5142 [94]

Options for the question have not been given. They are as follows:

A) 1/8

B) 3/4

C) 1/16

D) 1/2

Answer:

D) 1/2

Explanation:

Let the allele for extra digits be represented by D. Since it is a dominant trait, DD and Dd will result in extra digits whereas dd will result in normal number of digits. The woman has normal number of digits so she has dd genotype. The man has extra digits so he can be either DD or Dd.

The couple's first child has normal number of digits so she has dd genotype. She has obtained one d allele from her mother and another d allele from her father. Hence, the man's genotype is Dd.

Man = Dd

Woman = dd

Their children :

     D      d

d   Dd    dd  

d   Dd    dd

Half of the progeny will have Dd genotype and will have extra digits. Other half will have dd genotype and will have normal number of digits. So, the probability of their next child to have extra digits is 1/2.
