In cats, black fur color is caused by an x-linked allele; the other allele at this locus causes orange color. The heterozygote i

Luden [163]

The offspring that will be produced in the cross would have tortoiseshell fur.

<h3>X-linked traits</h3>

In cats, the male is XY while the female is XX.

Assuming that black fur is caused by the allele B and the orange fur is caused by A

A black female will have the genotype $X^BX^B$

An orange male will have the genotype $X^AY^A$

Crossing the two: $X^BX^B$ x $X^AY^A$

Offspring: $X^BX^A$ , $X^BY^A$ , $X^BX^A$ , and $X^BY^A$

$X^BX^A$ = tortoiseshell fur female

$X^BY^A$ = tortoiseshell fur male

First-division nondisjunction will only yield gametes with an extra chromosome, whereas second-division nondisjunction will only

statuscvo [17]

False

Explanation:

During the meiosis, the cell is dividing two times and chromosomes are getting replicated. In this process, there can be errors. One of those errors is called nondisjunction.

As a result of the meiosis one, the cell gets divided into two cells and each will carry 23 chromosomes each. At this stage, These chromosomes are connected in the form of sister chromatids. During the meiosis two, these sister chromatids will pull apart and form four cells. Each one will be haploid cells. In meiosis one, chromosomes will undergo crossing over so this separation of chromosomes in the second meiosis is know as disjunction. However, in this process of separation, the chromosomes do not need to get distributed correctly. The errors that happened in this process are known as nondisjunction.

In humans, meiosis will happen and form sperms or eggs( gametes) which are haploid cells and later they combined to form a zygote which is the diploid cell.

What is the function and an example of a muscle(tissue)?

ella [17]

The function of muscular system is to move our body, so if I had no muscle in my fingers I wouldn't have been able to type this answer.

For muscle tissue there are three types of tissues: skeletal, cardiac, and smooth muscle. They provide posture and body support, locomotion, and heat production.

Hope you understand what I said

Where do the instructions for making protiens come fron

borishaifa [10]

Answer:

Messenger RNA (mRNA) carries the instructions for making proteins. Like DNA, proteins are polymers: long chains assembled from prefab molecular units, which, in the case of proteins, are amino acids. A large molecular machine* called the ribosome translates the mRNA code and assembles the proteins.
