The correct option is d) When ICM cells from a gynogenetic embryo are injected into a normal embryo, embryonic growth is retarded.
.
The injection of ICM cells lead to failure in development of normal embryonal cells leading to small sized embryo when compared with test embryos.
Gynogenesis is a parthenogenic process of production of progeny which require only maternal genome.
The production of progeny require only maternal genome. The genome of paternal cell is destroyed by different processes including UV radiation.
It can occur in female only.
It is a form a asexual reproduction.

D Question 22 Identify a FALSE statement about X chromosomes: a) X chromosome inactivation occurs in all somatic cells of females. b) Xist inactivates only the maternally inherited X chromosome.

(1) A Drosophila male from a true-breeding stock with scabrous eyes and normal bristles was mated with a female from a true-breeding stock with normal eyes and javelin bristles. Both scabrous eyes and javelin bristles are autosomal recessive mutant traits. The F1 progeny all had normal eyes and normal bristles.

Question : The CDKN1C gene is a maternally imprinted gene that is important for fetal development. Mice that are homozygous null for CDKN1C, meaning no expression of the CDKN1C gene, have an overgrowth phenotype during fetal development and are large. a. ) A female mouse is heterozygous for a null allele of the CDKN1C gene. The null allele was inherited from her paternal parent and the allele inherited from her maternal parent is the wildtype DNA sequence of the CDKN1C...
