Why are genders different

Biology
1 answer:
sp2606 [1]3 years ago
7 0
I think from my personal conclusion genders are different because If there was only one gender no new humans or babies could come into the world at all because there wouldn't be any way for them to be created so if we have a boy and girl gender then we can easily make more and more people to come into the world everyday. Hope this helped

A wolf's diploid number of chromosomes is 78. How would the number of chromosomes in the wolf's body cells compare to the number
dimulka [17.4K]

Answer: The number of chromosomes in the wolf's body cells is 78 while the gametes has 39

Explanation:

Since each body cell under only mitosis to yield two daughter cells with equal number of chromosome as the parent cell (i.e diploid number, 2n) while sex cells undergo meiosis to yield four daughter cells with half the number of chromosomes as the parent cell (i.e haploid number, n); thus, the wolf's body cells has 78 chromosomes while the gametes has 39 chromosomes.

The domestic cat genome contains 2.9×109 base pairs. The length of linker DNA in mammals is 50 base pairs. Approximately how man
IgorLugansk [536]

Answer:

Number of nucleosomes in 2.9 * 10^9bp is equal to 1.47 * 10^7

Explanation:

For wounding one nucleosome, total length of DNA required is equal to 146 bp

The length of  linker DNA in mammals is equal to 50 bp

Thus , the total length of DNA that confides between two nucleosome is equal to the sum of wounding length of DNA and the linker length

= 146 + 50\\= 196bp

Thus, in 196bp length of DNA, the total number of nucleosomes is equal to 1

Thus, number of nucleosomes in 2.9 * 10^9bp is equal to

\frac{2.9* 10^9}{196} \\1.47 * 10^7

Which of the following describes the ability of a single gene to have multiple phenotypic effects?
bija089 [108]

Answer:

A, pleiotropy.

Explanation:

Pleiotropy - genes that have multiple phenotypic effects. Remember that phenotype means a physical characteristic caused by a gene, such as eye color or fur patterns.

Incomplete dominance - when neither allele is dominant and they mix together in the phenotype. A popular example is a red flower crossing with a white flower and resulting in a pink flower.

Epistasis - when two genes contribute to the phenotype, but one gene completely masks another gene. An example would be labrador fur colors.

Multiple alleles - 3 or more alternative forms of a gene, but only 2 alleles can occupy an organism. An example is blood type.

Hope this helps!
