Teratogens affect the fetus and not the mother because teratogens are "environmental exposures" done by the mother. It is an agent that can disturb the development of an embryo of fetus such as drugs or ingestion of harmful substances such as smoking and drinking. What happens is that the toxins are being ingested by the fetus through the umbilical cord where they are being supplied by oxygen and nutrition and instead of providing nutrients harmful substances are being ingested by a growing fetus.

TACATCCATCAGTTACGC A guanine replaced the 1st Thymine in the original DNA strand above, how many amino acids would be changed as
Julli [10]

Answer:

One amino acid

Explanation:

This question is describing the occurrence of the process of mutation, which is the alteration in the genetic sequence of a gene. In this question, a DNA sequence was given as follows: TAC-ATC-CAT-CAG-TTA-CGC. However, a SUBSTITUTION MUTATION took place in such a way that the thymine base was replaced by a guanine base to have mutated sequence: GAC-ATC-CAT-CAG-TTA-CGC.

Since the mutation is a kind of substitution mutation, only the codon affected by that mutation will change. This DNA sequence will be transcribed into a mRNA sequence. The mRNA will be read codon by codon (a group of hree nucleotides) to produce amino acid. Since one codon will be involved, one amino acid will be affected.

If two orange heliodors have a child, what is the probability their child would be red?
Stels [109]

Answer:

25% or 1/4

Explanation:

The gene for colour in Heliodors is controlled by two contrasting alleles that codes for Red (R) and Yellow (Y) colours. However, these two alleles exhibit incomplete dominance, which is a phenomenon whereby a combination of both alleles gives rise to a third intermediate phenotype that is a blending of the other two parental phenotypes. In this case, both colours gives rise to a heterozygous Orange coloration (RY) in Heliodors.

However, if two orange Heliodors (RY) are crossed, four possible offsprings will be produced with the genotypes: RR, RY, RY, YY. This shows a phenotypic ratio of 1 red: 2orange: 1yellow. Hence, the probability of having a child with red coloration is 1 out of 4 possible offsprings i.e. 1/4.

Expressing this in percentage, we have 1/4 × 100 = 25%.
