In fruit flies, the allele for red eyes, R, is dominant. Which genotype represents a white-eyed male fruit fly?

Answers

It would be "rr". This is due to the fact that recessive genes, like white-eyed, have to have a genotype with both recessive to show up.

The following choices are given;

A. XrXr. B. XrY. C. XRY D. XRXr

The answer is B. This is because the presence of the Y chromosome determines gender- which is male. In addition, it carries few genes than the X sex chromosome. Therefore, in this case, the X chromosome brings in the receive allele for eye color while the Y chromosome has no corresponding allele.

In most diploid organisms, they are two types of alleles for most genes which each on each set of chromosomes and at the same loci. In most cases, one allele is dominant over the other meaning that its presence masks the effect of the recessive allele. In the absence of the dominant allele, the recessive allele is expressed . Usually, the recessive gene is disadvantageous to the individual.

A young man wants to determine if he is a descendant of Henry of Navarre and Eleanor of Aquitainetwo of his favorite historical characters. He sends a cheek swab to a DTC company and is offered a choice (due to funding): The company can assess either the sequence of the man's Y chromosome or his mitochondrial DNA. Which should he choose?

Answers

Answer:

He should get his mitochondrial haplotype sequenced, given the genetic variation in mitochondrial sequences compared to Y chromosomes.

Explanation:

A haplotype is a group of genes within an organism that was inherited together from a single parent. The word "haplotype" is derived from the word "haploid," which describes cells with only one set of chromosomes, and from the word "genotype," which refers to the genetic makeup of an organism.

Genetic variation is a term used to describe the variation in the DNA sequence in each of our genomes. Genetic variation is what makes us all unique, whether in terms of hair color, skin color or even the shape of our faces.

The typical metazoan mitochondrial DNA (mtDNA) is a double-stranded circular DNA molecule, which encodes a conserved set of 37 genes, including 13 protein-coding genes (PCGs) plus the two ribosomal RNA (rRNA) genes and 22 transfer RNA (tRNA) genes.

This, together with other special characteristics such as faster evolutionary rates than nuclear genes, presumed maternal inheritance, and absence of recombination makes mitochondrial DNAs one of the most popular targets for population genetics studies and accurate identification.

Do venus fly traps have to be in direct sun light or shade

Answers

The Venus Fly trap requires a lot of sun to grow healthy and create the energy it needs through photosynthesis. The preferred conditions are to keep it in an area where it will get direct sunlight. If indoors I would recommend placing it by a window or under a heat lamp.

I hope this helps!

you want them in the sun. but at the same time not to much sun. 50/50
