Answer:
1 black : 1 orange
Explanation:
This is a typical monohybrid cross involving a single gene coding for eye color in MendAlien. The allele for black eyes (B) is dominant over the allele for orange eyes (b). In an heterozygous state, Bb i.e. combination of both dominant (B) and recessive (b) alleles, the MendAlien will be phenotypically black.
In a cross between a heterozygous MendAlien (Bb) and an orange-eyed MendAlien (bb), two of the offsprings will have a Bb genotype and be phenotypically black-eyed which the other two will have a bb genotype and be phenotypically orange-eyed. Thus, a phenotypic ratio of 2 Bb : 2 bb will be obtained.
This is also equal to 1:1 i.e. 1 black-eyed : 1 orange-eyed.
Answer:
There are two main types of stem cells: embryonic stem cells and adult stem cells.Stem cells provide new cells for the body as it grows, and replace specialised cells that are damaged or lost. They can divide over and over again to produce new cells.
