The correct answer is D) production of a zygote with a complete set of chromosomes with genetic material from two parents

The nucleus of a cell is <em>haploid</em> if it has a <em>single </em>set of chromosomes, diploid if it has two sets of chromosomes etc.

Gametes are haploid cells in sexually reproducing organism. During fertilization (conception) in organisms that sexually reproduce, two gametes (haploid cells) fuse with one another which results in a production of a zygote with a complete set of chromosomes with genetic material from two parents. In this case, the zygote is going to be diploid.

The right answer is D.

A gamete is a generally haploid reproductive cell specialized in fertilization, or gamy (that is to say, able to fuse with another gamete, complementary type if necessary), in eukaryotes.

The process that carries out the fusion of two gametes is called fertilization or gamy, it is the complementary event of meiosis. Fertilization produces a new single cell, called a zygote, whose chromosome number has doubled to 2n.

In a flowering plants species, red flower color is dominant over white flower color. What is the genotype of any white-flowering
katovenus [111]

Explanation:

<u>C. A red allele is present on both homologous chromosomes</u>

<u></u>

Homologous chromosomes are pairs of chromosome of similar lengths, banding patterns, and centromere positions, with genes at the same loci. For dominance, gene copies are present on both of the chromosomes; the dominat variant overrides the effect of the other recessive allele.

Further Explanation:

DNA molecules contain chromosomes that may have different forms called alleles. DNA, which is the genotype, is transcribed into mRNA and later translated into amino acids which are connected together by rRNA to form proteins which constitute the phenotype of an organism. DNA sequence mutations form new alleles, impacting the associated mRNA, and thus the encoded protein.

Homozygous individuals have a chromosome containing two variants of the same allele. Dominant homozygous individuals bear two copies of the dominant allele, whereas recessive homozygous individuals hold two copies of the recessive allele.

What is this an example of:
Karolina [17]

Answer:

A) a cow who's coat color is roan (red and white) : Co- dominance

B) A red flower and a white flower produce a pink flower: Incomplete dominance

C) In rabbits there are 4 different versions of the gene for coat color- Multiple alleles

Explanation:

Co-dominance can be described as a phenomenon in which the two different phenotypes of the parents can be seen in the offspring produced by them. For example, In the option A, the cow had a parent with red coat colour and a parent with a white coat colour. Both these traits were seen in the offspring.

Incomplete dominance is a phenomenon in which parents of two different phenotypes give rise to a new phenotype in the offspring which is not present in both of the parents.
