Answer:the plants u are correct
Explanation: I remember it from last year
Sex chromosomes contain genes that determine the sex of a person. Two X chromosomes result in a female 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.
These traits will be inherited according to the sex chromosomes they receive from their parents. Women recieve one X from the mother and the other from the father while men recievethe X from the mother and the Y from the father).
This will cause a <u>difference</u> in the expression of genes because women can become carriers of a certain disease while men either manifest it or don't (there are no carriers since the X chromossome is different than the Y)
In autosomal genes, the expression doesn't depend on the gender since the autosomal chromosomes contain genes that code for the same trait, and so the expression on autosomal genes in men and women are <u>similar</u><u>.</u>
The first geneticist has identified an obese allele that he or she believes to be recessive. We will define his or her allele as o1 and the normal allele as O1. The obese allele appears to be recessive based on the series of crosses he or she performed.
Cross 1 with possible genotype:
Obese (o1o1) × Normal (O1O1) F1 All normal (O1o1)
Cross 2 with possible genotypes:
F1 normal (Oo1) × F1 normal (O1o1) F2 8 normal (O1O1 and O1o1)
2 obese (o1o1)
Cross 3 with possible genotypes:
Obese (o1o1) × Obese (o1o1) All Obese (o1o1)
A second geneticist also finds an obese mouse in her colony and performs the same types of crosses, which indicate to her that the obese allele is recessive. We will define her obese allele as o2 and the normal allele as O2.
The cross of obese mice between the two different laboratories produced only normal mice. These different alleles are both recessive. However, they are located at different gene loci. Essentially, the obese mice from the different labs have separate obesity genes that are independent of one another.
The likely genotypes of the obese mice are as follows:
Obese mouse 1 (o1o1O2O2) × Obese mouse 2 (O1O1o2o2)
F1 All normal (O1o1O2o2)
