Answer: B
Explanation: Most mammals have only one pair of sex chromosomes in each cell. Males have only one Y chromosome and one X chromosome, while females have two X chromosomes. In Mammals, the Y chromosome contains a gene, SRY, which triggers embryonic development in a male.

The answer is mitochondria
Answer:
The correct answer is "high heritability".
Explanation:
Concordance, is a term used in genetics to describe the probability that one of the twins have certain trait if his brother certainly has it. A high percentage of concordance, such as 75%, is translated into high heritability since monozygotic twins have identical genomic sequences. Additional information to determine heritability will be to study the exposure to similar environmental conditions, since environment can also affect the presence of certain traits.
Answer:
(Fill in the blank) When comparing DNA and structural characteristics between plant species, the similarities that appear can indicate a genetic adaptation to a particular environment, between them.
Explanation:
The evolution of the spice indicates that there were changes in the environment where these plants were able to adapt genetically, and not only that but they transmitted it in their generations, that is why many manifest the same genetic code, if this gene was inherited among them it means that the species EVOLVED.
Otherwise, those genes that generate benefits for the plants but are not transmitted in the parent plants will not be considered as an evolutionary change of the species but individual of the plant.
The genetic changes produced by modifications in the environment translate into phenotypic changes, thus generating a more suitable species with a greater chance of survival.
