Autosomes space chromosomes that recognize traits that the organism and a sex chromosome identify the sex that the organism.

You are watching: Is the cell that results from fertilization a haploid or diploid cell explain


Diploid due to the fact that the mix of 23 chromosomes indigenous the mother and also 23 chromosomes native the father restores the diploid variety of chromosomes, which is 46.
Mitosis occurs throughout one organism"s lifetime in many cells in the whole body, compared to meiosis, which just occurs at particular times and only in the reproductive organs.
Do friend think the Y chromosome includes genes that are an important for one organism"s survival? define your reasoning.
Homologous chromosomes have actually the exact same genes, but have different versions of castle while sisters chromatids duplicates each other and also are produced by DNA replication.
An egg demands to provide the nutrients and also building blocks because that life come begin and also a sperm cell only demands to with the egg and deliver its DNA, so the is streamlined and also small.
If, during metaphase 1, all 23 maternal chromosomes space lined up on one next of the cell, would genetic diversity increase? Explain.
Genetic diversity would certainly not increase because the maternal and also paternal chromosomes would not arrange in new combinations.
Meiosis 1 starts a diploid cell and also the homologous chromosomes separate. Meiosis 2 starts with two haploid cells and also the sisters chromatids separate.
Mendel had actually no knowledge of DNA together the genetic material, however he was able to properly predict just how traits to be passed between generations. What does Mendel"s job-related in genetics show around the worth of scientific observation?
Careful observation deserve to lead to consolations also though the underlining factor or system behind the phenomenon is unknown.
Self-pollination of purebred plants always yield the same traits, for this reason Mendel can be certain that any kind of changes he witnessed were the an outcome of the crosses he made.
Mendel saw purple flower in the F1 generation, but both purple and also white flower in the F2. Just how did this help him view that traits room inherited as discrete units?
The devices of shade (purple and also white) were both personal present. They had neither blended tighter nor vanished.
If Mendel had actually examined just one trait, execute you think he would have emerged the regulation of segregation? Explain.
Most likely no, because by exploring with lot of traits, he could see that the proportion of leading to recessive traits in monohybrid constantly crosses ways.
All of this terms have actually something to do with a certain segment that DNA, of nucleotides. A gene is an ar of DNA, a collection of nucleotides that code for a protein. It can come in various forms, referred to as alleles, that code for the exact same general type of information, however the specifics vary. The locus tells wherein a details gene or allele is situated on a chromosome.

Explain why an organism"s genotype may be homozygous dominant, homozygous recessive, or heterozygous, but never heterozygous recessive?
Suppose you space studying a fruit fly"s DNA and also you discover a gene for antenna size on chromosome 2. What word explains its location, and also where would it be found in other fruit flies" DNA?
It is situated in the locus and also is discovered on other fruit flies" DNA on chromosome 2 at the very same locus.
If a recessive allele helps an biology reproduce, but the leading allele hinders reproduction, which will be an ext common in a population?
