What is the percent chance that the son will inherit male-pattern baldness?

Answers

Answer 1
Answer:

Answer:

100%

Explanation:

Pattern baldness if X linked and recessive.

A father with X^BY and a mother with X^bX^b have a son.

First, let us look at the result of the cross between the two:

X^BY   x   X^bX^b

male progeny: X^bY, X^bY

female progeny: X^BX^b, X^BX^b

The two sons resulting from the cross inherited male pattern baldness. Hence, the percentage chance that the son will inherit male pattern baldness is 100.

How does DNA influence physical traits? I will give you 10 points and branliest answer if correct and within 20 minutes answered.

Answers

DNA is the genetic holder in our body ! for any message DNA has to convert in RNA and then protein resulting in all the traits we have !

so on transcription DNA information is converted to RNA and during translation into protein .... thus these protein helps in building our appearance , our Personalities every thing !

so we can say DNA influence physical trait !
Genes are sections of DNA that carry your information. This information is used  to build and maintain cells that make up different biological traits. Such as eyes, hair color, freckles,and etc. In addition, the DNA splits in two, and forms two different DNA strands during cell replication. ( So the DNA molecule is being copied to produce two identical DNA molecules). However, sometimes this process is not perfect, and mistakes occur. These mistakes may change the way an organism is constructed  or functions.

How does semi-conservative replication help prevent mutations during DNA replications?

Answers

DNA replication is the process by which two DNA molecules are produced from one parent DNA molecule. DNA replication is semi conservative, this implies that, each strand in the double helix DNA molecule act as a template for the synthesis of a new, complimentary DNA strand. Because semi conservative method has a DNA template that is already accurately formed, the probability of having errors in the newly formed strand is drastically reduced.

Semi-conservative replication is a process of DNA replication in which each new DNA molecule formed contains one original strand (parental strand) and one newly synthesized complementary strand.

This type of replication occurs during the cell division cycle, ensuring that the genetic information is faithfully copied and passed on to the daughter cells without introducing significant mutations.

By combining accurate base pairing, proofreading, and repair mechanisms, semi-conservative replication ensures that the newly synthesized DNA strands are as identical as possible to the original parental strands. This fidelity in replication is vital for preserving the genetic information and preventing mutations that could lead to genetic disorders, cancer, or other harmful consequences in the offspring cells.

Is the following sentence true or false? It is easier to synthesize new elements with very large atomic numbers.

Answers

Answer (True/False):

FALSE

Explanation:

Atomic number defines the number of electrons and protons in an atom. where as synthesizes means to produce something chemically. Keeping both the statements in view, it is not easier to synthesize new elements with a large number of electrons and protons. Though this process can be done for the small atomic numbers.

No, not particularly. For those beyond a certain point, you actually need to create the precursors first and then combine them again.
