Question

Connecting the concepts: genetics concept map can you correctly organize these terms associated with mendelian genetics?

Answer 1

A- Gene- it's a sequence of DNA that code a protein with a certain function.
It determines a certain trait and  is passed from parent to offspring

B- Chromosomes- a long sequence of DNA that contains multiple genes and is structured like an X; has a centromere in the middle.
Chromosomes can be autosomes( when they are not carrying sex-related genes) or allosomes (the X or Y chromosomes) 

C-allele- it's a variant or alternative form of a gene (for example, in the gene that codes the color of the eyes the alleles possible are: blue, green, brown). For every gene, we have two alleles- one inherited from the father and the other from the mother.

D- homozygous- When the two alleles are the same we say homozygous. That can be either both dominant alleles (AA) or both recessive alleles (aa).
Since they are the same variant, they code the same trait.
When these variants are different they have another term.

E- Heterozygous- When the two alleles are different from each other, we say heterozygous. Most of the time, it's represented by one dominant allele, and a recessive allele (Aa).
They code different traits.

F- Dominant- Mendel concluded that some alleles are dominant and others are recessive. When one dominant allele is present, it's enough to make the recessive allele unexpressed. In other words, it 'hides' or masks the recessive allele.

G- sex-linked traits
Sex chromosomes contain genes that determin the sex of a person. Two X chromosomes result in a femal and one X plus a Y result in a male.

In those chromosomes, there are genes specific for each gender, and in those chromosomes, there are genes that code for certain traits- the sex-linked traits.
