Question

Question 13 (1 point)

If a gene is haploinsufficient, a heterozygote containing only one fully functional allele does not express enough gene product for a normal phenotype.

Question 13 options:

	True
	False

Question 14 (1 point)

For a gene with complete dominance, the recessive allele has no effect on the phenotype of a heterozygote.

Question 14 options:

	True
	False

Answer 1

Answer:

Q13) True

Haploinsufficiency – a locus shows haploinsufficiency when a single normal allele is unable to generate a sufficient amount of its gene product to produce a normal phenotype (when half of the normal amount of the gene product is not enough). When the heterozygous state manifests an abnormal phenotype, the disease trait is considered dominant.

Q14). True

Ex:

A-   Dominant; a- recessive

“a” allele has no effect on phenotype in heterozygote. It effects on phenotype when it is on homozygous condition
