On average, what percentage of infants born to 45-year-old mothers have down syndrome
insens350 [35]
Probably 3 %. a mother could give birth to a child with Trisomy 21 at any age because Trisomy 21 is a mutation and mutations happen all the time. Not all mutations are as Down Syndrome. A child born to two homozygous brown eyed parents could be born with blue eyes even if no one in the family had blue eyes. The child would develop blue eyes due to mutation.

Which advance in biology resulted from developments in cell technology?
Mariulka [41]

Answer:

Immortal cell line

Explanation:

An immortalised cell line is a population of cells from a multicellular organism which would normally not proliferate indefinitely but, due to mutation, have evaded normal cellular operation and instead can keep undergoing division. The cells can therefore be grown for prolonged periods in vitro

Immortal cell lines are a very important tool for research into the biochemistry and cell biology of multicellular organisms. Immortalised cell lines have also found uses in biotechnology.

Character displacement differs from resource partitioning because character displacement _________. A. is a fundamental differen
mr_godi [17]

Character displacement differs from resource partitioning because character displacement  is directly linked to the evolution of genotypes that have allowed alternate resource use

<h3>What is genotypes ?</h3>

An organism's genotype is made up of all of its genetic components. The alleles or variations that an individual carries in a specific gene or genetic region are also referred to as the genotype. The number of copies of each chromosome found in that species, also known as ploidy, determines how many alleles a person can have for a certain gene.

In diploid organisms like humans, there are two complete sets of chromosomes, which means that each person has two alleles for each gene. Homozygous refers to a genotype when both alleles are the same. Heterozygous refers to a genotype when there are two distinct alleles.

Phenotype, the observable qualities and attributes of an individual or creature, is influenced by genotype.

The issue of high cholesterol can sometimes run in families. If an individual has two normal alleles, then he is phenotypically
statuscvo [17]
In the case of the gene that determines high cholesterol in the blood, the two alleles express incomplete dominance.
What this means is that the dominant allele is not completely dominant over the recessive allele. If the allele was completely dominant, even one allele would be enough to determine the individual's trait as dominant. But in the case of incomplete dominance between the alleles, the heterozygous individuals that have one dominant and one recessive allele are an ''in between'' phenotype.

kumpel [21]

Answer:

Answer is D.

Explanation:

The first cleavage division can be explained or described as the series of first cellular division of the zygote after fertilization.

In this case, the process of recoiling of the shell of the snail can not be categorized as one of the examples at this stage.
