Are caused by mutations in genes on the X chromosome, one of the two sex chromosomes in each cell.
X-linked diseases
What is a characteristic of viviparous?
The embryo develops inside the female body
Type of reproduction that happens when two parents make gametes that combine at fertilization to produce offspring with gene combination unlike their parents.
Sexual
A reproductive strategy that involves development of a female gamete without fertilization (“female power”).
Parthenogenesis
What is a characteristic of ovoviviparous?
The embryo develops inside an egg that remains inside the females body
Embryonic stage in which three germ layers of the embryo form in a process called histogenesis.
Gastrulation
Starts with a single cell that copies its DNA and then splits into two identical cells. Most bacteria reproduce this way.
Binary Fision
The female part of the flower called the __________
Pistil
One mutated copy of the gene in each cell is sufficient for a person to be affected.
Autosomal dominant disease
Mention an example of an organism that reproduces by fragmentation
Starfish
Embryonic stage in which the neural tube is formed
Neurulation
Two different versions (alleles) of a gene are expressed, and each version makes a slightly different protein
Codominance
Locus is defined as:
Specific location of a gene
In which trimester kidneys start to work.
1st trimester
Embryonic stage that happens in the first 10 days.
Germination
The male part of the flower called the __________
Stamen
In which trimester occurs the formation of heart and blood vessels.
1st Trimester
In which trimester you can Identify the baby’s sex.
2nd trimester
Is a form of asexual reproduction in plants, in which multicellular structures become detached from the parent plant and develop into new individuals that are genetically identical to the parent plant.
Vegetative reproduction
In elephants, allele for long trump(L) is dominant to the allele for no short trum(s). A mother with the genotype Ls and a father with the genotype Ls produce an offspring. What is the percent chance that the offspring will have short trump
25%
Phenotype refers to the ______________________ of an individual.
